Footprint calculator can be carbon footprint calculator or ecological footprint calculator, which can give data about your impact on environment.

Depending on the environment, it may be possible for a footprint to last more than 30 years. If an environment is exposed to consistent changes and elements, such as rain, wind, etc., then it is just about impossible for a footprint to last that long. In an environment where virtually no elements are present, in a cave for instance, then it could be possible for a footprint to last that long.

We can effect many lives by our carbon footprint and many ecosystems. Because of humans carbon footprint the Earth has effects. The biggest one would be global warming.
