We are just dust wainting to be cleaned...

Is human activity a substantial cause of global climate change? Well i consider that we can't do that much to make a big diference in the climate change. Yes we are polluting the seas and chopping trees as maniacs, but, we are too small to think that the global warming is our fault.

First of all, climate changes had happen from the start of this piece dirt. The dinosaurs and other kind of species went down to extintion because of climate changes, the earth got freezed several times with out the help of any living been. It is an inevitable cicle.

Another reason is that the earth it's to big to think that we are doing something to provoke such changes. It is too egocentric to have the idea that we are making colapse an entire planet. The thing that are we doing is helping in a fraction to this changes. Polluting the air and the seas, making the earth less fertile, and so. It's no even meaningful, we are just too small. If we ever stop to use fosil fuels and go full green using bicicles. The global warming will continue his way, the ice would melt anyways.

I think that we should be prepared to this changes, making more efficent ways to produce energy, food, water and tecnology. Because we can't stop the climate change, it'll come more early than late. The annihilation it's a barrier that every living creature has to overcome and we are not going be the exception.
