Would there be a way to reverse the pollution process?

Would there be a way to reverse the pollution process?
Callum Heenan from Somerset (Aged 5-14)

  1. One of the best ways to clean up pollution is to use microbes. These are single cell organisms, invidible to the eye, that can ‘eat’ just about anything.

  2. The effects of pollution are very difficult, if not impossible, to reverse. However, it is possible to limit the damage we are currently causing to Earth by substituting fossil by renewable fuels as means to produce energy. This means replacing coal, nuclear energy and above all oil by the Sun, the wind or hidrogen as sources of energy to produce, among other things, electricity.

    Unfortunately, such renewable energies are currently less effective than fossil ones and their development requires big investments. Governments are not very keen on them, since the outcomes are long term and will begin being visible after the election term.

    Examples of the poor concern with renewable energies are the recent reduction of the maximum CO2 emission quotes of the Kyoto Protocol or even the war in Iraq, to a large extent founded on oil!
