America and pollution

I recently read a blog post about global warming by Archie Richards. This is my response to his ridicule of everybody who is worried about the way we destroy this planet.

The Vikings never grew grapes in Greenland or in Newfoundland. The temperature in the year 1000 was just slightly higher than 50 years ago. The ice in the Arctic is receding in a much higher speed then expected, which leaves the polar bears in that area in a dire situation. The ice on Greenland is also receding at a very dangerous speed. The ozone layer is getting thinner and even has holes in it, especially where I live. I could go on, but there is no doubt that man made pollution is the cause if these changes. —-

The worst polluters are the US and China, but despite this, they refuse to sign any international agreement to reduce the pollution. Many Americans argue that the effects of the pollution are NOT man made, but a “natural” part of a cycle. This has been disproved again and again, but America and China are continuing to spew out all the destructive gases that are so dangerous to all of us.
