I think there's plenty of denial on both sides frankly. There are people who think there's nothing to worry about and it's all a hoax. There are also people who insist that everything is getting worse by the day and the world is going to come to an end. And there are people who are too young to know any better, that never heard of every car burning lead, every block in places like Pittsburgh having a smoke stack spewing out toxins, companies dumping in the rivers and lakes, Indians on commercials crying about litter on the road, and never experiencing actual smog. In many ways the environment is the cleanest it's been in my lifetime. Other ways not. And then there are those that think having the strictest regulations on Earth will magically fix everything, when in reality, jobs and production will seek the most profitable source in countries that don't give a damn and increase net global pollution. Full disclosure, I recycle, I car pool, I walk when I can, my next vehicle will likely be an EV and I've done cleanup dives. But as is true of nearly every debate in existence, reality is usually somewhere between the extremes.
