 Every one of us leaves behind an ecological footprint. It is the amount of land and water that is needed to support our given lifestyle using the current technology available. We need natural resources to survive, and using any natural resource will have some sort of impact on the natural environment. While we all need to use natural resources, we do have a choice on how we use them, how much we use, and what we do to preserve them. These choices help determine the size of our ecological footprint.
You often hear of people mentioning the word sustainability when talking about environmental resources. If a population's lifestyle is sustainable, that means that they could keep living that way forever without running out of resources. The size of your footprint is a good way to determine whether your lifestyle is sustainable. |
