Sometimes, I must admit, it is difficult to convince myself of the scientific basis for global warming and alternative energy. The data seems too easy to manipulate. Can scientists really predict temperatures 100 years into the future when it is so difficult to predict this year’s hurricane season? Perhaps with some probability of error.
What is clear, however, is that the thinning ozone layer isn’t getting any smaller around the Antarctic. Instead the hole has gotten bigger since the late 70s. And that is not good.
We know that biodiversity is important for our survival. Learning how different organisms and animals live and breath provides valuable, sometimes lifesaving, insight into our own lives. So we should do what we know we can while we can to protect the species that we have — perhaps not to protect against cataclysmic global collapse in the distant future per se, but to address the dramatic change that’s happening now.
