The Canada Pine Beetle
For some time now, the extremely destructive Pine Beetle ( Dendroctonus ponderosae ) is ravaging huge areas of Canada’s forestlands and its destruction is so virulent, that it is leaving massive and easily visible scars across otherwise green foliage landscapes. In numerous areas where the pine beetle is active, various solutions for its eradication have been tried and some of these in themselves, are so toxic in nature that they would normally be classed as being a larger risk than the beetle they are attempting to destroy.
These beetles have an average life span of about one year and generally, their eggs are laid through the bark of a tree where they develop into larvae that stay under the bark all through the winter months. During the spring the larvae continue to feed under the bark and then they will change into pupae during the months of June and July. During the rest of the summer and into fall, the new adult pine beetles leave the infested tree through emergence holes they create and after drying themselves in the warm sunshine, they take off to mate and commence a new cycle by laying the next generation’s eggs under the bark of new trees.
During the time they remain under the bark of a tree, they are known to transmit a fungus type substance that stains the sapwood of the tree a blue colour. Other than discoloration, this blue colouring appears to have no adverse affects on the actual structural integrity of the tree. However, we must not forget that the damage has already been done and like a rolling snowball, it gather momentum and range of spread with each summer that comes. These beetles prefer mature trees such as lodge pole pines which are considered mature after eighty years of growth and in the Province of British Columbia, current statistics show that there are three times more mature lodge pole pines than they had over ninety years ago. Hot and dry summers make the trees more stressed and thus more susceptible to attack and infestation by this ravenous little creature. Trees which have been attacked will turn red roughly one year after the infestation and then, between one and two years later the affected trees will turn grey and all of their needles will fall off.
Another interesting fact about these little guys is they do not like it too cold! Their eggs, larvae and pupae are very susceptible to very cold temperatures and if these temperatures remain below minus 35 Celsius for a prolonged period of maybe a week, then this will kill off the eggs, larvae, pupae and generally sizeable portions of the beetle population in that area of cold weather. This being said, unless we suddenly enter the start of a new ice age all across Canada, these sporadic cold spells are unfortunately not enough to rid us of this continually spreading plague of destruction. Yes, there are action plans prepared and in place and yes, the Canadian Ministry of Forests and Range are really trying to get to grips with finding a solution to this costly problem but to date, the efforts and methodology being used has had little or no effect on the overall problem.
The good news is that an answer to this massive problem does exist and better still, it is an answer, which consists of no chemicals, no toxins, no poisons and no danger to either the forest or to the people who would apply the solution. This answer can be found right now in the form of a golden all natural organic fluid formulated around a cedar oil base. This fluid can totally eradicate the pine beetle and a few other nasty insects at the same time. It is not cheap but then again it is not as expensive as some of the other treatment that have been tried. It is non hazardous and will not harm the environment in any way and it is here and available right now. Unfortunately, for now it appears that here it must stay as the Ministry of Forests and Range are continuing their quest with what they feel they know best. Maybe someday, hopefully soon, they will realize that we can defeat this natural pest by using a totally natural substance.

Water Efficiency - Water Used in Generating US Electricity
In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.
You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.
You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.
Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.
Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.
For a simple reason. It takes a lot of water to produce electricity.
How much? 5% of all US water? 10%? Can’t be as high as 25%?
Electricity and water?
I thought the issue was fossil fuels and greenhouse gases
The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.
Their grand total: 408 billion gallons per day withdrawn for all uses.
The number 1 spot, weighing in at 48%, was thermoelectric power.
Irrigation earned the runner-up prize at 34%.
The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.
How much water is used in generating electricity?
Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.
Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.
According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.
The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.
Nationally:
- Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
- Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
- Geothermal power plants add another 2 billion or so gallons a day.
- Most renewable energy technologies require little or no water for cooling.
These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.
Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.
How much is 3 billion gallons per day?
The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.
Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.
How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.
Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.
48% of all water use: We’re Number One!
How much is 195 billion gallons per day?
Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.
How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.
So, let’s get a higher-level view to help us.
Lake Erie holds 116 cubic miles of water.
Nationally, thermoelectric power uses 195 billion gallons a day - or 64.2 cubic miles a year.
We drain Lake Erie every 22 months.
But the water used is returned to its source.
So what’s the issue about water use?
Power generation returns 98% of the water back to its source (bay, lake, river, ocean).
It’s the environmental consequences.
The Pace Energy and Climate Center explains it neatly:
Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.
Examples include:
- The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
- At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
- The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)
The diversion of water out of the river removes water for healthy in-stream ecosystems:
- Stretches below dams are often completely de-watered.
- Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
- A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
- By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
- The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
- This often eliminates native populations of fish and other wildlife.
- Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
- As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.
The cleanest kilowatt is the one never used:
Back to those compact fluorescent lamps and LEDs
PowerScorecard.org explains the solution:
By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.
They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.
In short, reduce your use of electricity.

Save the Plastic Bag or Ban the Plastic Bag?
As part of the conservation and environmental movement worldwide there are several campaigns aimed at banning the plastic bag. These fit in perfectly with going green at home and with our longer term life styles.
A quick search on the web will take you to the San Francisco Bay Area, “Bay vs Bag”, to the Daily Mail’s (UK) “Banish the Bags” as well as similar situations in Canada, Holland, China, elsewhere in the US and even Zanzibar.
A lot of the focus is based on the damage done to wild life, including sea mammals and birds; the effects on waste and the average number of bags used per person in different countries. In one of the lists I saw, Singapore was topping the list at 625 bags.
One of the targets is to reduce by 10% the yearly consumption of these bags.
On the other hand there are also “Save the Plastic Bag” campaigns, with the plastic industry behind it. Their main focus is highlighting what they call misinformation. Their points are based on “exaggerations” on the damage done to wild life; errors in how plastic bags are made (from ethane gas that would otherwise be burnt and not petroleum); effects of co2 vs methane; potential job losses and so on.
On the banning side of the argument, there can be exaggerations as well as questionable scientific data - questionable as in anybody can question it, after all to have an argument you must always have at least two points of view.
From the “saving” the industry point of view, there can be many counter arguments to the data that is presented. And this is quite understandable, after all their industry could be hit very badly. (This just reminds me that all businesses have a life time curve that goes from birth, to growth, to maturity and finally to demise. The time scale can be as short as a year to as long as a hundred years or more, but the end result is that it is replaced by something else).
Some of the arguments are saying that nets and not plastic bags are causing marine life casualties, that paper bags are a worse alternative (side stepping the plastic bag issue) and basically attacking the “plastic bag misinformation campaign”.
Very probably both sides are looking to make their points by reducing or ridiculing their opponents point of view. But the overall issue is still there - are plastic bags affecting our environment?
To get back to the plastic bag banning situation, where paper bags have the negative effect of more trees cut, the information that is being retrieved is very important. But it must also be as objective as possible. Having said that, we know that it takes literally centuries for plastic to degrade and this should be the foremost argument.
Just to expand a little on the paper bag argument, which is totally reasonable, the option is not to cut more trees. The options are to recycle and use bio-degradable alternatives.
In the old days, when plastic bags hadn’t been invented but grocery shops had, natural fiber bags were used and the customers were the ones who brought their own to the shop.
With just a little effort on the individual front, these campaigns wouldn’t be necessary.

Antarctic Peninsula Climate
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Aqueduct For Florida A Modern-Day “Roman” Germ of an Idea
The west coast of Florida remains trapped in an ongoing drought. In Pinellas and Hillsborough Counties (Tampa and St. Petersburg/Clearwater) severe restrictions on water use are in place. Even the use of reclaimed water for lawns and gardens is now restricted. The rainy season is not yet here; but in past years the amount of rainfall received during the wet months was far below the historical average, so that reservoirs and ground water supplies have never had a chance to recover.
The situation is quite different in northern Florida, in the Panhandle and all across the State close to the Georgia border. The weather in those parts of the State is generally wetter, and more consistently so, than the weather farther south.
Yesterday, our local St. Petersburg Times carried a story (with photographs) of the damage which is now being inflicted in Madison County (which borders Georgia) by floodwaters from the Withlacoochee and Suwannee Rivers. The storms which produced the rain moved from west to east across the Panhandle over the past week, to the point at which the Withlacoochee crested at 89 feet, four feet above the record set in 1948. So far, the rising floodwaters have destroyed or caused severe damage to almost 200 homes and lesser damage to 500 more, all areas combined. Two people are known dead, and one person is missing.
Quite apart from the possibility of reducing the tally of deaths, personal injury, and property damage which even a partial remedy for river flooding in these areas might entail, it boggles the mind just to consider the sheer waste of so much fresh water. Most of that damaging flood water will be gone forever as it eventually finds its way to the Gulf of Mexico. That’s a shame, because so much of it could be put to good use in the west coast, central, and other parts of the State where it is so desperately needed. The waste is not just limited to damaging flood waters, either. The “top of Florida” is blessed with more rainfall, on average, than it needs. Obviously, the flow of river water into the Gulf represents a volume of water which has not been put to good use.
In passing, we acknowledge that the flow of a certain amount of river water into the Gulf is said to be necessary for the health of the shellfish beds near the coastline.
Even so, it seems inadmissible to stand by and do nothing but watch a surfeit of water in the northern counties lay waste and then go to waste while there is such a great need for water in other areas of the State. Surely there is a partial remedy which might ameliorate the problems in the affected sections.
The Romans found a way to move big volumes of water over considerable distances. Surely we can build on their success - and on successes over the centuries since that time - by constructing an Aqueduct system to bring excess water from the northern Florida counties to drier areas to the south.
The best part is that the right-of-way is already in place! It’s called Interstate 10 and Interstate 75. Take a peek at a map of Florida. Find the intersection of I-10 and I-75. The Suwannee and Withlacoochee Rivers are close by, as are other rivers. There are others to the west, and I-10 probably crosses every one of them.
Excess water could be fed into the Aqueduct lying above-ground or underground in the median of I-10 at various points along its route, and then fed south toward Tampa and St. Petersburg/Clearwater in that part of the Aqueduct lying within the median of I-75 and I-275. Do you see how obvious that is?
If ever there was a perfectly-planned right-of-way for a particular purpose, although not part of the design at the outset, this is it.
There would be hurdles. There always are. Will and determination were invented for the purpose of overcoming hurdles.
It seems to me that the construction and operation of The Florida Aqueduct is an undertaking which private capital should undertake. It need not cost the State a penny.
Let’s see whether anyone steps up to the plate.

Get Rid of Junk Mail - Go Green
Four million tons of junk mail is sent every year…at least half of which is never even opened. You probably are aware that your name, address, and spending habits are regularly being traded and sold on the open market. By investing half an hour now, you can rid yourself of most of the junk mail for up to five years…and save a few trees while you’re doing it.
So here are a few tips that you can work on to lessen the load of junk you get every day:
- Product warranty cards do not register your product…that was done when you purchased it. They are used to fin out about your interests and your income for the sole purpose of junk mail.
- When ordering something on the phone, tell them specifically to not give your name and address to other companies for any reason.
- Any time you donate money or order a product or service by mail, write on it in large letters, telling them not to sell your name and address.
- When the junk come by first class mail, cross out the address and bar code, circle the first class postage and write “refused: return to sender”.
- Your credit card companies are the worst offenders and probably sell your name and address more than anyone else. Stopping them is easy; you just need your address and social security number. One call does it all for agencies Equifax, Trans Union, Experian and Innovis. Dial 1-888-5 OPT OUT (or 1-888-567-8688) 24 hours a day.

Yahoo Vs Google - Who’s Greener?
Silicon Valley is known for both innovation and hype. Recently, this pool of innovation has extended beyond bandwidth to the protection the environment. Google and Yahoo, the search engine giants, are both headquartered in the Valley and have been making headlines by greening their offices, reducing energy consumption, and carbon trading. The PR motivations are obvious, but are the green benefits really there? To set apart the hype from reality, we have analyzed the green value of both Google and Yahoo’s headquarter facilities.
We looked at the ecological services provided by green landscape features such as trees and open space (i.e. grass). Grass and trees are pervious surfaces, meaning they allow water to permeate into the ground. Roofs, sidewalks, patios, and asphalt parking lots are examples of impervious surfaces, where rainwater drains into the public storm drains. Heavy metals, oil, and other pollutants are carried off parking lots in rainwater, which often lead directly to open water habitats, where fish, birds, and reptiles live.
In terms of ecological services, trees and grass have been proven to:
1. Remove and store carbon from the atmosphere,
2. Remove certain airborne pollutants,
3. Permits rainwater to seep into the ground as opposed to draining into the stormdrains, and
4. Remove certain waterborne pollutants.
Here is a look at how green Google and Yahoo really are and how the measure up against each other.
Google Green Report
Google’s headquarters, the Googleplex, covers 44 acres, nearly 50% of which is grass or tree canopy. This is an impressive paved to open space ratio. The grass and trees on the Googleplex remove roughly 2 tons of carbon from the atmosphere per year, or 0.04 tons per year per acre. In addition, 530 lbs. of air pollution are removed per year (e.g., ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter), or 12 lbs. per year per acre. It was assumed that the parking lot of the Googleplex is asphalt, and not a type of porous pavement, so the cost of managing rainfall runoff from the Googleplex is $4,474 per year, or $103 per year per acre. The abundance of grass and tree canopy on the Googleplex go a long way to offset the water quality impacts of the paved surfaces (mainly the parking lot). On average, the grass and trees reduce water pollution by 6%, as opposed to the entire property being paved.
Yahoo Green Report
The Yahoo headquarters, Yahooplex, covers 28 acres, a third of which is grass or tree canopy. This is a classic ratio of paved to open space for large office complexes in California. So far, par for the course. The Yahooplex removes 0.36 tons of carbon from the atmosphere per year, or 0.01 tons per year per acre. 114 lbs. of air pollutants are removed per year, or 4 lbs. per year per acre. In terms of rainfall, the cost associated with runoff is $9,219 per year, or $331 per year per acre. The grass and tree canopy help offset the paved areas with a 2.3% reduction in water pollution as opposed to the entire property being paved.
The final green analysis?
Google kicks Yahoo’s butt, largely due to the forethought, or luxury, of the Googleplex having 50% of its property surface providing green services. The good news for both Google and Yahoo is that over time, as trees grow, so will the tree’s canopy and mass, thus storing more carbon and removing more air pollutants.
Green next steps for both Google and Yahoo is to:
- Install porous parking surfaces, allowing up to 80% of rainwater to seep into the ground,
- Install green roofs, absorbing rainwater while reducing cooling costs and energy consumption, and
- Planting larger trees on the south and west sides of the buildings to reduce cooling costs and energy consumption.
While we crunched the hard numbers to settle the Google vs. Yahoo green debate, this report illuminates the great opportunity that awaits these two Silicon Valley giants to harness the ecological services of green surfaces.

The sun is shining across the hills of West Cork as I listen to the story of Earthday told by a team of evangelists with nothing but Earthday business on their minds. In 2008, visionary Simon Ford started a group to bring like-minded, positive people together in socially conscious activities. He called the group Social Traffic and right now that group has Earthday business on its mind.
The group’s first major campaign centers around Earth Day with an event named, Earthday Birthday a global birthday party for Mother Earth. Earthday 2009 and the celebrations that will go with it is all set to clamor its way across the social media landscape like some all embracing vine, covering the sometimes harsh elements of the online world with a softer, greener facade which many hope will last for more than a lifetime.
Earthday 2009 is a global celebration and a day to spread awareness of people’s destructive impact on the planet. But before you jump right in there and start changing the world on a massive scale here’s a few simple things you can do to make a difference right now, tomorrow and every single day after that.
Here’s my list of top five things to do to celebrate Earthday 2009 and reduce your impact on our planet;
1. Plant a tree or two. If you’re feeling energetic plant a whole field full.
A tree will absorb CO2 and other forms of pollution, provide a home to hundreds of creatures, help to create and retain soil and performs a whole host of other ecological functions. And, in case you needed a reminder, will leave a lasting legacy of your time on the planet.
2. Walk to work for a day, a week or a whole month. You’ll feel better and the earth will be a much healthier place to live too.
You might even want to think about joining a car sharing scheme and make it a permanent part of your work life balance to drive to work only one day a week and sleep the other four in the passenger seat while someone else does all the hard work!
3. Dry your dishes naturally. Turn off the dishwasher at the dryer stage of the cycle and leave your plates and cutlery to dry themselves for a change!
4. Turn off all your plug sockets before bed. Maybe spend the evening in the dark for one day a week and treat the kids to a few ghost stories before bedtime!
5. Don’t be a water importer.
Get rid of your supply of bottled water, keep a jug of fresh tap water in the fridge and reduce the damage we do to the environment by producing plastic bottles to hold gallons of mineral water that tastes no different to the clear, fresh water that is piped through your home.
So, if you’ve got business on your mind this Earthday, perhaps you should take a few minutes to look around you and realise how precious our planet is and how beautiful that small piece of turf is right outside your window.
If you want to know more about this subject and how you can make a difference take a look at this great squidoo lens all about Earth Day Birthday right now.
