It's not about fixing what has already been destroyed and what will be destroyed regardless at this point, but about minimizing the losses.
We should do whatever is in our best ability to slow down global warming and limit it's impact on the ecosystem.
I agree this is not about fixing it because it is really hard to do we should just minimize the damage,
We should do something to prevent it for being worst,Just think about what the future would be how would we live our life with just less natural resource around us being destroyed?
Tree's and plants being cut down ,Polluted water every where how could the next generation enjoy their life ?
