Yes the site is good for me and younger kids, it's very easy to work with and anyone can figure out how many earths they would use. You can do a more complex questions or simple questions.
My foot print is 5.2 earths
Myself 1. Walk more 2. Eat more localized food 3. Grow my own food
The School 1. Turn off lights to save energy 2. Turn of computers 3. Turn off any unused electrical sources
The Community 1. Have people walk instead of driving 2. Have people switch to natural gas 3. Start a community garden
The connections that the video has to our footprint is that in the movie it talks about how much resources we waste and how much out earth actually have. We are using so much resources without even thinking about it. We are killing our earth and we should change the way we live.
