I agree, what we should do is apply even greater amounts of pesticides to certain countries while letting others try to fight ecological collapse. then in a hundred years we can see who is right and who is dead.
The idea that we need more data is lazy, shortsighted, and used as a primary argument to justify doing nothing.
The neighbor's house is on fire, Sparks are falling on your roof because of a breeze and you are holding of fighting the fire because the wind might change and we might be able to do nothing except high five each other about how smart we were.
In life, you never know enough to make the perfect decision. You have act on the existing data, not wait until the choice you should have made becomes clear.
I'm not saying we should not act. I'm asking if we know what we are up against.
