The universe created this world as a perfectly healthy place to live for all in co-existence with nature but greed of the man/woman kind  has converted this heaven in to a living hell merely by asking for more all the time. We are still far from extinction provided we take steps now and reduce our needs in all types of formats.
It will be a great day when all of us commit ourselves to do something to make it better but if that is too difficult let us start in a small way by reducing our physical needs.
