In reply to the discussion: In big climate move, EPA set to unveil tough limits on auto emissions [View all]crickets
(25,983 posts)21. Yes, that is a big part of the issue.
When it comes to resources of any kind, the earth only has so much to give, and right now the human race is likely past the carrying capacity of the planet.
https://worldpopulationhistory.org/carrying-capacity/
The ecological footprint is a measurement of the anthropogenic impact on earth. It tracks how much biocapacity (biological capacity) there is and how much biocapacity people use by comparing the rate at which we consume natural resources and generate waste to the planets ability to replenish those resources and absorb waste. Today, our global footprint is in overshoot. It would take 1.75 Earths to sustain our current population. If current trends continue, we will reach 3 Earths by the year 2050.
There is some disagreement about the attempt to reach a true estimate of Earth's carrying capacity, and world population growth has slowed but not yet peaked.

The number of people Earth can support is not a fixed figure. The way humans produce and consume natural resources affects how our environment will be able to sustain future populations. As Gerland said, "When it comes to carrying capacity, it's a matter of mode of production, mode of consumption, who has access to what and how."
One study published in the journal the Proceedings of the National Academy of Sciences(opens in new tab) found that if the population of the United States switched to a vegetarian diet, the land used to grow crops for humans rather than animal feed for meat production would feed an additional 350 million Americans. High-income countries, where females have increased access to education and family planning, tend to have lower birth rates and smaller family sizes than middle- and low-income countries, according to Max Roser, director of the Oxford Martin Programme on Global Development in the U.K., writing in Our World in Data(opens in new tab).
Put another way, there may be an upper limit on how many humans Earth could support, but we dont know exactly what that figure is. It varies based on how we produce, consume and manage our resources. For Cohen, if we want to affect how many people planet Earth can support, we will need to decide "how many people want Jaguars with four wheels and how many want jaguars with four legs."

Lucky us, Republicans are so het up about controlling women and going back to "the good old days" that they're trying to make women pop out more babies at any cost. Ugh.

End car culture, EVs only marginally better. Public transit, 15-minute cities.

There will always be cars, the difference is that we will not all be required to own one.

I don't think that, I think rural people are threated by trashing ICE's and gasoline

The biggest cut to auto emissions we can make long term is not having children.
