The rule is: If something bad happens: blame Global Warming/Climate Change. So, is the decline of bees bad? Yes, they do a vital job.
They help to keep our food growing. So bees are good. Their decline is bad so it must be caused by Global Warming.
Now the stage is set to try and get some research funding to try and demonstrate it. If your research does not show a relationship then, more research is required - send more money.
Where I live they are declining because of farmers spraying insecticide on everything. The guy up the road sprays his apple trees about once a week, if it wasn't for the bees he would have no apples but he just keeps spraying away and killing them and then there are big sprayers and airplanes spraying all the fields . They don't stand a chance.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
