I'm just going to put the first thing that comes to mind here and I have really no knowledge about this other than the basic idea of some of the elements you mentioned and some alleged pros and cons of their effects.... and stuff
So I'm just going to throw this out there and then I'm a go looking and then I'll be back to check if any of you want to help we can cross things off as to where I'm wrong or even other obvious things that we can exclude.


I am going to assume you're telling the truth only because I have had a silent thought that the bugs are getting bigger year to year, but idk if this is true or recorded, we may have to check....anyway, If it is true, and if the truth of the greenhouse effect is raising the carbon dioxide and if we are losing vegetation in certain areas then that would put more in the air to take up by the remaining plant life and that could increase growth. I say this because the climate change thing (but i don't agree with them on its cause or that there is one aside from a natural cycle of the earth) and their destruction of land and farms to prove their point which isn't about being green.
