You should know there surely is climate change happening, the things we have from our civilization like all the transport of ourselves and everything for us and all the agriculture with so much for the animals for feeding us are causing it to happen. We in fact need to live in very different ways to not be giving our contribution to that or the others destructive things happening in the world, it would be with simple ways not using things from civilization still and growing what we want and need to use, ourselves, along with any involved in that with us. Ice melting in the Arctic is showing this happening and how critical it is.
