Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

Lights
I admit i have a bad habit when it comes to turning off lights when leaving a room. For now on i am going to try to remind myself every time i leave a room to turn off the lights.
I agree with reducing energy to help the environment. When you consume less power, you reduce the number of toxic fumes released by power plants, conserve the earth's natural resources and protect ecosystems from destruction. The most notable way to reducing the energy that will help the environment is by decreasing power plant emissions and going solar. To generate electricity, most power plants burn coal, crude oil or other fossil fuels. Although this method of creating energy is relatively inexpensive, our planet plays the price -- carbon dioxide, sulfur dioxide, and nitrogen oxides are just a few of the byproducts that come from traditional methods of power generation. The benefits of going solar are to use fewer fossil fuels and relying more on natural resources. Solar produces no harmful emissions that hurt the environment. It's a clean, renewable process that uses the most natural of all resources, the sun. When you opt to cut back on energy use, you also help conserve limited natural resources that would otherwise be used to power the power plants. Less demand fo r energy creates less demand for harvesting fossil fuels. Turning off the lights at night or washing clothes in cold water can save trees, coal, natural gas and more. Also, excessive energy use can harm animals and ecosystems. In conclusion, reducing energy helps the environment by protecting the air and prevent climate change.
