Climate change can't possibly be a hoax because climate has always changed.
There isn't a climate emergency and there is certainly no "climate collapse," which is a phrase used by politicians to raise money from guilty rich liberals like Jane Fonda, who called covid-19 "God's gift to the Left" in 2020.
All of the computer modeling and scaremongering has mercifully turned out not to be true. The ice caps haven't melted, New York City and Miami are not underwater except financially and because their populations have rebounded, even polar bears rarely get on the news unless they catch covid.
When I was a kid it was about water and air pollution, and how you should recycle and buy organic and by those measures I've always been an environmentalist.
But even that isn't so simple.
The air quality in Los Angeles in the 1970s/80s was gawd awful, a thick brown layer of smog hung most evenings over the basin and caused sunsets of impossible colors. First lead was taken out of gasoline, and that helped.. higher fuel efficiency cars also helped. But by far the main reason that the skies in Los Angeles are clear most days of the year is because There are no factories in Los Angeles anymore. They've all been moved to where labor is cheap and lives are even cheaper. The CEOs who tell you how green and woke they are also had no choice but to move their assembly plants and factories to China, Vietnam, Bangladesh. It's just business
The vast majority of plastics that are recycled aren't. Up until a few years ago China was the major importer of plastic waste for recycling. And then it was discovered that China often was sending the plastic on these immense barges to the poorest countries on Earth to be buried or incinerated, or simply dumping it in the sea. China is also the world's worst polluter, and estimates run high for the amount of plastic in the oceans originating from China's rivers and estuaries as well as Chinese vessels and fishing fleets.
Just as there was about to be criticism China announced to the world they were not going to take plastic any longer, since plastic when it's recycled can not be reused for food or medicines and therefore there's only so many recycled plastic garments, footwear, and cheap furniture that people are willing to buy. It was a simple issue of supply and demand, and so now most of the plastic you throw in your blue container wind up in the same landfill as the trash.
Michael Shellenberger and others have suggested that plastic could be used in super efficient incinerators as a fuel, and it's an idea I suspect won't go anywhere like fourth generation nuclear power which could potentially use the huge quantities of nuclear waste being stored at aging and decommissioned powerplants as a primary fuel source. Some countries like New Zealand and Australia have actually passed laws banning nuclear power, which probably seemed like the right thing to do after Chernobyl and Fukushima. However these laws have the consequence of also stopping research and development of new technologies utilizing radioactive isotopes.
Which is a huge irony since nuclear power is essentially net zero carbon, apart from power plant construction. On the other hand solar panels contain such a dizzying array of toxic materials that they cannot be recycled and wind up in landfills. Also most of the world's solar cells are manufactured in China using prison and slave labor, mostly ethnic Muslims in China's west.
And so on
