The U.N. estimates that human being No. 7,000,000,000 (that's seven BILLION) was born on October 31, 2011. That means that the human population on earth has doubled since 1965…..and this dangerous growth rate continues.
The lifestyles and commerce of affluent Westerners squander energy and generate greenhouse gases that are cooking our planet. Everyone else on the planet wants the goodies we enjoy, and they're moving quickly to get them. Some degree of harsh climatic change and seasonal disruption of agriculture and desperate disruption of life on our seacoasts is already guaranteed, because we and our elected representatives have dithered in our pathetic national and international efforts to come to grips with the very expensive changes we're going to have to make in our lifestyles and commerce if we want to keep the good times even modestly rolling.
The science on global climate change is well-grounded and indisputable….some radio talk show hosts, and a couple presidential candidates, and some doctrinaire political partisans haven't figured it out yet, still, they're going to sweat just like everyone else. Some companies and industries are cravenly and criminally trying to delay implementing costly changes that will protect the environment.
Not so long ago I privately reassured myself that "I'll be dead before worldwide climate change and global warming starts to cause the really bad stuff." I was concerned, but in a rather abstract way. My first grandchild was born 11 months ago. Very sadly, I expect that she'll be alive when the really bad stuff starts to be unavoidably obvious. Abstract concern isn't good enough for me anymore. How about you?
