An ecological footprint is a measure of how fast we consume resources and the land needed to deal with the waste created. Our diet has a large impact on land use and on the environment. Using a device, investigate how much of an ecological footprint you have.
Australia’s average is about 6, the world’s average is 2.8, the sustainable average is 1.7
