How does not conserving energy effect the earth? & How does conserving energy help the earth?

failure to conserve energy means that more energy will have to be produced. Since most of that energy comes from the use of currently non-replaceable fossil fuels we will eventually run out of that resource. In addition to that, the fossil fuels tend to be burnt which puts more pollution into the environment. Each individual has a miniscule effect however since there are estimated to be somewher around 6 to 8 billion people in the world it adds up to quite a bit in a cumulative effect.
