Climate change - what are we afraid of, exactly?

Climate change is a real thing, and I'm not going to say that I don't care about it. But I will say that I don't worry about it to the extent that it feels like we're asked to. I don't see it as the biggest crisis of our time, and in fact, I think that mindset can be quite dangerous. I'm more just confused why we don't appreciate our ability to master our environment, and aim to harmonize with the planet, instead of remorsefully deify it. I don't relate to the worship of this earth goddess concept - nature is amazing, but it's also terrifying. Our ability to control and coexist with it should be commended and encouraged, not demonized and shamed. And indeed, it is the poorest of humans who pay the price for our seemingly virtuous environmentalism. How arrogant are we to shill these sorts of ideas to the less fortunate?
