I do, in fact, realize just how deep down we are in the proverbial hole. But that doesn't mean that solutions can't continue to be found and worked on; although to be perfectly fair, I can admit that, those few things alone, while helpful in both the short and long terms, aren't going to be the end all, be all by any means.
Climate change will continue, and it will get worse. That, unfortunately, is certain; what is also inevitable is that many, many, millions more lives will be adversely affected by this disaster in the coming decades. Water shortages will continue, and wars will continue to be fought over that and other resources, which will contribute to the death toll. Dictatorships may arise in various places, including quite possibly some parts of Europe, should the far right be particularly successful there. And there is even the possibility of terrorists using WMDs against various countries, including perhaps the U.S. & Canada! How our future will develop over this next century, on the other hand, will largely rely on what actions are taken then.
But even if some of us may have given up hope, there are many more who haven't. Do keep in mind that Rachel Carson didn't throw in the towel when things looked bleak. Neither did the people who supported CFC banning and the Clean Air Act. It's because of perseverance that we have made progress over these past 50 years, and it's been significant. If anything at all, the latest problems tell us that action is needed more than ever, and that there are many who are willing to rise up to the challenge in whatever manner possible, large-scale or personal.
