Do Something or We're Screwed

Roberts' "Do Something or We're Screwed" article at grist.org: http://grist.org/climate-change/climate-change-is-simple-we-do-something-or-were-screwed/

This is a great article and video. I get so tired of the arguments that arise about climate change. It doesn't matter if it is human-caused or a result of the climate naturally changing. Either way, we have to adapt in order to survive. My personal opinion is that even if the Earth is naturally warming, we are contributing to and accelerating that process at unprecedented rates. An introductory geology course taught me how the various cycles on this planet work, most notably the hydrological cycle, carbon cycle and the nitrogen cycle, all of which effect the atmosphere. We are certainly changing these cycles drastically, especially the carbon cycle. I don't understand how people can believe that our actions do not have a negative impact on the delicate balance on this planet that allows life to survive. Just the fact that we have not found life on any other planet that we have been able to study, goes to show how amazing, miraculous and delicate life is. Period. The conditions have to be so precise. We have become so consumed in our daily lives that we often fail to look at the larger picture, including how amazing and wonderful this planet and all of life is. We often take life itself for granted. It makes me sad to think about what kind of future we are leaving for future generations and inhabitants of this planet. If we are wrong about our impacts on the Earth, that's fine, but if we are correct, it's ridiculous that we are not doing more to change that. It doesn't seem like something worth taking a chance on. It seems best to err on the side of caution; that we are causing damage. It's obvious in some ways, such as deforestation. We need to quit putting ourselves at the center of everything. Without the health of the planet, our health suffers. There are many things that are in our control, in the power of our own hands, and like David Roberts says, we need to do something or we're screwed.
