It's not surprising that some of the greatest human minds such as the late Stephen Hawking believe humanity will destroy itself with greed ignorance and stupidity. Personally I've felt this conviction for decades. The idea that the earth has unlimited resources and that we can keep taking from it and killing the animals within it forever without paying the ultimate price is incredibly stupid. Our planet is our home a precious wonderland that was once filled with so much of beauty, a magical universe of diverse animal and plant life that is now under increasing threat of total destruction. This world can't go on indefinitely and survive without humanity making some effort to value what we have and look after it. Greed is killing our own existence as we pillage and plunder whatever the nature can supply as if we don't need it, that it's only use is to make money or exploit in in some way. But we are wrong. The air we breathe the water we drink the rainforests the oceans every bit of it is part of a whole that enables us to survive. Without it we will perish and sadly it seems perhaps too late already.
