They have. Most of the motivation for there being an EPA and things like the Clean Air and Water act had nothing to do with climate. They were motivated by things like smog days in major cities because of unbreathable air or entire generations of children in some places having cognitive deficits thanks to lead poisoning and toxic waste being dumped in water sources, or fears of cancer rising thanks to industrial contaminants. Even with respect to fears of biodiversity collapse, factors like farming monoculture, overfarming, overfishing, and overhunting, encroachment of human habitats, roads blocking migration paths, have all been and remain larger factors than anything climate-related, and environmentalists have historically raised and continue now to raise concerns about all of these things. The largely successful global effort in the 80s to put an end to commercial whaling was because the largest threat to whales continuing to exist was humans killing them on purpose, not oceans getting warmer. To the extent that all of these efforts were resisted anyway, it had nothing to do with general population climate alarmism fatigue. It's that people resist any restrictions whatsoever on freedom of commercial activity and think of everything in nature as either a resource that can't be exhausted or a resource that doesn't matter if it gets exhausted because it can either be replaced with something else or they'll have gotten rich enough by the time it's gone that it won't affect their personal ability to profit and the portion of future generations they care about (their own descendants) can simply inherit their wealth and not need to continue the activity that generated it.
