Air fresheners contain many harmful chemicals such as dichlorobenzene, naphthalene, and formaldehyde. They are both detrimental to us and the environment. Instead of using them determine the source of the odor and eliminate it by throwing it away, hanging it on the clothesline, opening a window, or washing it.

This solar house can be found at Parc Jean-Drapeau in Montreal. It was designed by students from McGill University, the Universit?? de Montr??al and the ??cole de technologie sup??rieure for the 2007 Solar Decathlon, which is an international competition that took place in Washington, D.C. If you go see this house you can get a guided tour and learn about the construction of the building and other new environmental innovations.

The U.S. EPA estimates that 75% of our waste is recyclable. However, in many municipalities it is very common to only see garbage bins. If your town or city is one of them you can contact your local town hall and suggest they adopt a recycling program where recycling and waste bins are placed side by side, such as shown in the figure. When there is only waste bins, citizens have little choice but to toss any waste, even if it is recyclable in the garbage. These garbage bins will then be emptied and sent to a landfill, where the waste will sit and very slow decompose.

By using a laptop instead of a desktop computer you can reduce the electricity used by a whopping 75%. However, don't forget to turn off your laptop at night.

According to National Geographic, you can increase your fuel efficiency up to 23 percent by reducing your speed from 70 mph to 55 mph (or approximately 110 km/h to 90 km/h).

I love to bike. Here in Canada we have a long winter which means no biking for about 5 months of the year. So when April 15 comes around each year and the bike paths open I can't wait to hop on my bike again. Not only is biking an environmentally friendly activity it is also great exercise and you get to explore new uncharted territory. Many cities are now becoming more bike friendly by building new bike paths, so check out what your city has to offers. Maybe there is even a bike path that connects where you live to where you work. It is also fun to just get on a bike path a see where it leads you. Maybe you'll end up at a beautiful lake or park. You will be amazed at the new places you can discover by just getting on a bike path and seeing where it leads, just don't forget to bring your camera and some water.

Your carbon footprint is a measurement of the impact that our daily activities have on our environment and climate change. It allows us to better understand the amount of greenhouse gases we are generating by the way we are currently choosing to live. It takes into account all the greenhouse gases we are individual generating through the burning of fossil fuels for our electricity, heating, transportation, and so on.

The average footprint for people in United States is 20.40 tonnes
The average for the industrial nations is about 11 tonnes
The average worldwide carbon footprint is about 4 tonnes
However, the worldwide target to combat climate change is 2 tonnes.

Damon Matthews who is a professor in Concordia University's Department of Geography, Planning and the Environment has just completed a study with another group of scientist from Victoria and Britain concerning carbon dioxide emissions. Their results which will be published today in Nature, reveal that for every tonne of carbon dioxide released into the environment, there will be a 0.0000000000015 degrees of global temperature change. Furthermore, the findings indicate that it does not matter over what time period the emissions occur.

So what is the volume of 1 tonne of CO'?

1 tonnes = 1 000 kg = 1 000 000 g
1 m?? = 1 000 L
1 mole of CO' = 12 g + 2 ( 16 g ) = 44 g
1 tonne contains 1 000 000 g / 44 g/mole = 22730 moles of CO'
According to Boyle's law, at 25??C and 1 atm, 1 mole = 24.47 L
Therefore, 1 tonne of CO' = 22730 moles ?? 24.47 L/mole = 556200 L = 556.2 m??

According to the American Forest and Paper Association, the US uses approximately 10,000,000,000 paper bags a year.

Now, how many trees does that equal?

Answer: Well, the California Energy Commission estimates that one 15 year old tree produces 700 paper bags. Therefore, approximately 14,285,715 trees are cut down each year to fufill the demand for paper bags in the US.
