I am a bit upset about all the downvotes,i know it's bad etiquette to complain about that but I just wanted to say how questions of curiosity shouldn't be looked down upon. This isn't my field but climate change is concerning, so I simply wanted to know why certain solutions (however naive) were not being pursued.
Don't let it worry you. Downvoting is essentially a thoughtless act so you can pretty much ignore them. It just means some people dislike what you wrote without considering the substance of it.
In reality it's a good question and it prompted some good answers.
Cheers.
