By the term 'This World', I presume you mean this 'age' or this world's system that is going down hill rapidly and of course you are right.
The thing is, it has been going down hill ever since the Garden of Eden and the birth of Cain for it is Cain's world in which we live. Cain's descendants rule this world, not Adam's descendants.
As for recycling you need to understand that recycling causes more pollution than making things from new.
The only constructive thing man can do is plant more trees, for trees are more than capable of dealing with man's pollution. Trees love carbon - period!!
In the end though the only answer to man's problems is the return to this earth of the Lord Jesus Christ, which won't be long now, for we are now in the closing stages of Cain's (the Devil's) age.
