Fine. You can live in idleness and continue to believe what you may. Predictions may be exaggerated but the message is clear - humans need to change living behavior or there will be consequences.
Think about the things you throw away and know that they are going to sit in a landfill - never to degrade until a nuclear explosion. For example: plastic grocery bags, plastic cups, deodorants, aerosol containers, broken glass, waxed food containers, electronic equipment, broken light bulbs, kitchen appliances, the list goes on. If you think that nature can handle all that then I'd like to move into your world.
Sorry if i offend anyone but I strongly believe in making a difference.
