We need to think wisely as a society.
People don't realize that every individual decision they make has an impact on a social and historical level. If someone eats a snack and throws the package / wrapper[?] in the street, he or she might not realize the impact of that little action, because he/she doesn't see anything big and bad happening at the moment. The package doesn't catch fire, start an earthquake or cause something catastrophic. It just stays there and then later it moves to somewhere else.
But these insignificant[small] actions have caused many problems on our planet on a big level [large scale], [such / so that] we actually have climate problems at the earth. The person who throws a little package in the street is now part of an historical and collective negative force that is changing the natural way the earth has worked for many years. That little action is part of a catastrophic force, so big and so bad that it modifies something that seemed to be permanent/immutable.
