Sometimes I think that biggest thing that we could do to help our beleaguered planet is to impose term limits! Corruption at the top is becoming deadly especially at the bottom. Ehrlich highly says that with our current crop of legislators that he isn't hopeful. They don't believe in science he says. I think they just don't care instead. They don't have to. Being in congress is long term employment and a cushy job at that.
Once back when I was young and still had reason to own a comb, the 1964 World's Fair (do they still have those?) was a big deal. The future was there on display in front of our eyes. One exhibit talked about population in the future. There was a digital clock showing over 3+ billion people were alive at that very moment with more being born every few seconds.
Much was made about how future populations would be fed by the green revolution, modern agriculture and ... the astoundingly bountiful richness from the sea. Endless supplies of fish year after year forever! Hundreds of millions of tons of fish which modern technology could now access easily.
No mention was made of waste, by catch, over fishing and sheer avarice and stupidity. We would eventually give a license to one boat to catch herring but it wasn't allowed to keep the other fish it caught and had to throw them back into the sea dead. Nearby another boat had a license for cod but couldn't keep any herring it caught etc.
Until now we find that up to 90% of the fish that we eat are gone. Many food fish species are endangered. Salmon runs on the west coast right now are dying from fungus diseases caused by river water too warm for their species. Once yearly salmon catches were tabulated in millions of tons. Salmon was cheaper than canned cat food. How expensive is salmon now?
The oceans are becoming devoid of fish and instead are filled with jellyfish and dead zones. Our economic system of unregulated exploitation was too subject to corruption and has made our species ... fools.
We were smart enough to know better but we over exploited our food supply and damaged its ability to regenerate.
We have met the enemy and he is ...
...just as stupid as we are.
