Globalization, logically, has the greatest impact on global issues. And the original "global" issue is nature itself. Long before humans invented "environmentalism" -- and long before humans -- the planet was chugging along as a well-balanced if brutal eco-system. Fresh oxygen was pumped into the atmosphere by huge rainforests; the big fish culled the little fish; and natural fires managed the prairies.
Now humans are increasingly aware of the way the Earth's environment has been changed by human activity. And we are also aware that nature pays no attention to national borders. While laws attempt to control the flow of capital, goods, and labor around the globe, no legislature, committee, or king can control the way winds blow greenhouse gasses or where ocean currents carry oil or waste.
One nation might pass strict environmental protection laws. But they will have little affect if neighboring countries don't pass similar laws. Only global agreements, therefore, can truly get all nations to act together to improve the environment. Because of this, some of the first truly global civil movements have been those which intend to protect the environment.
