Do you want this to be
the world surrounding you?
if no, then behave!
When I watch doom day movies, this is the thing that scares me most, to see this beautiful planet like this- without trees, birds, animals…
I dont even like to think about any chances of seeing such a sight.
But, if we human beings act the way we are acting at present, we wont need any catastrophe, we will slowly turn this earth into a desert planet.
Stripping away greenery, then paving that place with concrete. Is not it so wise!
Then, when the time comes, most probably their offsprings will try to digest that concrete as food.
