Generally speaking, people as individuals are simply not willing to change and will always point to someone else as being the problem.
The only thing that has a chance at "solving" climate change and environmental collapse is individual action and individual change.
This nonsense-belief of "individual change" as a necessary precursor to societal adaptation of necessary policies is an absurdity most likely cooked up by industry spin-doctors.
Of course, it is exactly the other way around. Abstract insight into a problem and its solution needs to be implemented into policy by the government. That is it's primary function.
That's all well and good if you live in a dictatorship, but those of us under democracy are lead by the same individuals that who won't act. Only once they have decided to act and feel the need to clean up the outliers who continue to go against the grain will they use their governmental powers.
This has nothing to do with democracy per se. The constituency in the US isn't directly involved with legislature. They vote for "representatives" who supposedly defend their interests in a role of mediation.
In reality, long-term interests of the public are of little import. Public perception is easily swayed, what counts more than votes is, who has money and knows how to use it.
Those responsible steal themselves out of accountability.
Pro-animals and vegan movements have different roots. Dairy & meat industry is trying its best to discourage individual actions ... their concern with plant based alternatives and naming of stuff is a clear indicator. Even terms like almond milk (1000 years old term) is somehow a problem.
Plastics are very visible within our environment, that was the reason behind population accepting recycling.
Animals do not have the voice and the horrors of their lives are generally hidden from the consumers. If most of the population remains ignorant incl. politicians, we cannot expect that anything will change.
The driving factors of climate change: * industrial * end of list
Individuals changing their behavior will not do a single thing to solve, reduce, or delay the climate crisis. It’s a feel-good thing for individuals to do, yes, but it doesn’t help in the slightest.
