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?

Light Bulbs
I believe one of the biggest problems that we face is how much energy we use just through the type of light bulbs in our homes. Most houses are filled with incandescent and florescent bulbs. These use more energy therefore more carbon than LED bulbs. A solution to this problem is replacing all the light bulbs in your house with LED ones. This will essentially reduce your carbon footprint levels.
I agree. Pretty much everybody has a light on wherever they go, and there isn't really a way around that, so if LED lights were used everywhere, then the carbon footprint of lighting would go way down. It is pointless to try and keep the lights off all the time, so a great way to reduce carbon emissions would be to replace all of the incandescent and florescent bulbs.
Also, tube lights (found in classrooms and shops) can be converted to LED for less than another incandescent bulb!
I agree with this because it is a simple solution and will save much more energy than the other bulbs would. LED lights have so many more uses in comparison to other bulbs on the market and using less energy is just one great benefit of people replacing some bulbs inside their home. LED lights save more energy, last longer, and are cheaper in end result because of its lifespan. Therefore, I think people should at least replace a dozen lightbulbs in their home as a start.
