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?

why reuse bottles
It is always a good idea to reuse water bottles because you will not have to pay for a new one and you can save it for a mother time. over 50 billion bottles are bought each year. Plastic water bottles are destroying are world. Bottles that are dumped in the ocean get washed in to a big floating wast land. The wast land is bigger than Texas. I think we should all bring are water bottles every were we go so we will not have this happen.
I completely agree with what you are saying. I also think that even if someone just got a plastic bottle, it is just as important to reuse that as it is to bring a reusable bottle with you. So when using a plastic bottle, instead of throwing it away, refill it.
Reusable water bottles last a long time and can be very helpful. They are usually a lot more convenient now, as they can keep your water cold for longer and store more water. Also, reusable water bottle cost less than single use water bottles and give you more in the long run.
