Answer and Explanation:
The ecological footprint is an indicator of sustainability at an international level that integrates all the human impacts over the environment, considering the necessary resources and the generated residues to maintain the modern consumption model. It refers to the productive ecological surface needed to produce resources to consume by one person and to absorb the residues that are produced.
By constant contamination and indiscriminately use of natural resources the impact generated by human in the earth is unmeasurable.
The tragedy of the commons refers to how some people, acting by their own needs or interests, may exceed the use of natural resources, affecting their population and, therefore, other users. These individuals over explode resources thinking only in the present, but not in the future.
The ecological footprint as an indicator makes visible the unsustainable lifestyle of human beings, especially those of the first world.

More developed countries are over contaminating and over exploding natural resources, affecting other countries of the third world, and even themselves.
