One of the drawbacks of suddenly having time on your hands in what is a busy life is that you tend to think.
Not all, possibly any, of your thoughts are any good, indeed cogent or even rational thought is a difficult time consuming and thankless effort.
Time I have had though and thoughts appear.
Apparently they are proposing to release GM mosquitoes in Florida to combat the upsurge in Dengue Fever. These beasties have a suicide gene which means they die if the don't get a certain chemical and will pass this on to their offspring.
It sounds brilliantly simple. Less Mozzies, Less Dengue. What could possibly go wrong?
I live in a country where two positives can make a negative. Aye Right!
Lets start with the understanding of complex systems. Big fleas have littler fleas upon their backs to bite them. Do we understand the full ecosystem that could be affected here? What would be the effect on smaller organisms seeking a new host? Is it possible there is a substance sufficiently similar to the required chemical to fill the gap?
If anyone answers other than "We don't know" to at least 2 of those questions then they are blatant liars.
Bill Gates et al are apparently proposing geoengineering to overcome the climate change problem.
We can't even agree there is a problem, never mind have the hubris to think we can fix it with technology, is the first and starting issue.
If we ever agree there is a problem we then look at the fixes and have to consider the career of Thomas Midgely. Lead in petrol was an awfy good idea in the 1930's. Freon would change the human race.
Yep they did by causing the Ozone holes we are now affected by.
Science is so fascinating and can do so much good it is a great pity it is rapidly becoming the new religion. While great strides have been made we still have so many unknown unknowns. Humans tend to look for definitive answers. If God didn't do it Science will. Not the best maxim on which to gamble the only planet we have.
We do have a simpler way of starting to combat climate change. Use less.
Unfortunately this interferes with 3 holidays a year, new this and that, and most importantly of all consumerism. It is much easier to expect a Deus ex machina to just wave a wand and make it all go away, than suffer the least inconvenience in our lives.
Something to think about if you have the time.
