No. We should be proud that we are mastering metal and machine. We should be happy that we are learning to mould the environment to our needs. We should be proud that the evidence of our existence will not dissipate the second we are gone.
It will, cause when we will get erased, it will be or from nukes, or from the sun, or from the poison we produce everyday that will consume everything, or it will stay and all the creatures that live on earth will mutate/get extinct/die from hunger/die from heat/die from poison-smoke/die from us =D
Best solution - Venus Project, we have the resources to live more then 10k years in a much better and stronger environment with less crime and pollution =D
