Sounds like enough to pay some people for some months or a year or two - a combination of experts, part-time specialists, cotractors, etc. - to do things like gather some data via their contacts, hack together a meta-study, put out a glossy report andsome press releases, etc.
I think the bigger point is that there's an overwhelming amount of money going to push the opposite narrative. A quick search revealed that Tyson alone spends well over a million annually on lobbying and I am sure the industry at large spends significantly more on this issue alone.
Ah, I was more focused on the effectiveness as opposed to the quantity, i.e. if you have a million dollars, that could be decent way to spend it, given the world we live in.
I see what you are saying - that it's not enough compared to what the other side spends.
