Humans killing their selves?

I have thought and thought and found that humans are killing them selves. Everyone cutting down the trees is making it so the carbon dioxide doesn't get turned into oxygen. and all these companies releasing carbon dioxide into the atmosphere just doubles that. The Earth is not meant to have so much carbon dioxide in the air as it is today. I believe it is going to trigger another ice age and kill off the humans for good. The earth needs to be treated as if it were a treasure, we are not treating it like this.. Look at our oceans all polluted oceans are not meant to run with all this shit in them floating around. We are like viruses eating up all the resources on earth. Look at all the animals that are disappearing off the Earth. We are destroying the Earth day by day and we need to stop. What we need to do is use the technology we do have and switch to solar/wind power for energy and use hydrogen/electric cars and stop polluting the Earth if we want our children's children to be here. In the future what we need to do is design a giant Island type structure over an ocean and live inside that structure of course it would take 100's of years to build it would be ran by the sun with solar power on the roof. At least that way our children have a better chance to keep the species going until yellow stone erupts and blocks the sun light from heating the Earth and throwing us into an ice age that way or a meteor/comment hitting Earth but what is the odds of that happening any time soon. Anyways if we stop polluting and cutting the trees the earth needs and eventually move into a structure like that reserving the land we should survive for far longer. All these wars are destroying Earth as well we all need to just unite and save the human race from killing it self. We need to stop going to space we do not need to be going there we are not meant to leave Earth that is just hurting the Earth and space. That is all I got for now... What do you guys think?
