Global Warming

In Chemistry, we're watching a video about Global Warming, a phenomenon where gases increase the size of the Ozone layer which keeps in more heat from the sun around the earth. This residual heat is now melting the polar ice caps and is a threat to most life on earth. This movie has informed me of information that I've never known about global warming. Things such as it will dramatically raise the water level of the oceans so that it will encompass quite a bit of land. I personally think that global warming is a threat, but not an immediate threat. Yes, it's something that could end the world as we know it, but this is still only a gradual effect that will only become critical over the next few decades. We still have time, no need to be bothering people like we're all going to die tomorrow.
