All 10 of the largest U.S. meat and dairy companies have lobbied against environmental and climate policies, resisting climate regulations, including rules on greenhouse gases and emissions reporting. This is according to a study by New York University, which examined the political influence of the 10 largest meat and dairy companies in the United States.
Well it appears to be the top 10 companies, so it is almost certainly quite close to 100%. Still not 100% though so it's wrong of course, there's no point saying something incorrect even if it's pretty close to the truth.
Not really. Small farmers generally couldn't care less about lobbying, and represent over 90% of the meat and dairy farms in the US. Literally, they cherry-picked Big Ag and the clickbait headline extrapolated conclusions about a completely different demographic.
