We humans often imagine too much, the earth is polluted of course it is, we accept but somehow it's managed to sustain itself beyond reasonable measure. We won't be here to see if it's destroys or doesn't. We just have to find it in us to do better for our world
And better for ourselves as a species. Too many people take the, I won't have to live it as I'll be dead, approach.
Exactly however it is we need to develop a positive mindset and preservation because we have to do better for the next generation else they might not have a world to live in
I think one of the paths of innovation we take is to improve life for those to come.
