The reef isn't our only worry either. We are losing fresh water supplies, forests, and even land everyday due to pollution. Look at the Aral sea for example, It used to be the 4th largest lake on earth. In 20 years it is hardly anything. The impact is devistating to the region causing massive climate changes. It's irritating to know that the technology is there and its just money, low priority, and lack of interest by governments around the world that keep "green" from being implemented. There is something like close to or over a million jobs i heard recently that could be created just in america by implementing some of these green economic strategies. Everything has a breaking point and everything dies. So i guess the real question is, What is earth's breaking point. At what point will earth cease to support life? How close to that point is earth? Can we continue to waste supplies and pump fossil fuels into our atmosphere for 10....20....50 more years before it's a serious problem? I guess it's kinda like smoking....no offence to anyone....Everyone knows that for the most part smoking kills, there are a few people out there that it won't kill, but, for the most part it will kill you. People know this, there are commercials, ads in magazines, it's even printed on the packaging. But how many people read all that media and quit right on the spot. Many people will try to quit multiple times and fail, some the next day they quit smoking and never smoke again. Some slow down and get to the point where they just don't anymore. I just wish there was a patch we could use that would help allieviate the dependency on polluting the earth.
