This is why I don’t believe people when they say “we don’t have an overpopulation problem, we have a distribution problem”
Because if everyone in the world had my lifestyle, we would be emitting an insane amount of carbon. And I don’t want my standard of living to go down, and in fact I want everyone to live as nicely as I do. So clearly we need fewer people.
Assuming you live in North America, travel is highly inefficient with personal cars and high airplane usage.
Meat consumption on the other hand is a lifestyle choice. Personally, if be willing to reduce mine if we stopped subsidizing the industry and therefore stopped incentivizing such high consumption.
I'm on a budget. I eat less meat than the average North American, but I still need protein and meat is a lot less expensive than many of the alternatives, partially because we subsidize the meat industry so much.
It makes jack shit of a difference to the environment if there is one billion or two billion starving people. They're not the ones burning carbon or eating steak.
Only when assuming that it's necessary to pollute as much as the 1% do to achieve a similar standard of living. It doesn't have to.
Looking at energy production, developing nations can and are skipping several decades of advances. They don't have to go through the same phases where they chop down all the trees, dig up all the coal and burn all the oil. They can go directly to renewables, because the technology already exists, and they do.
In regards to food, it's obvious that we need to advance our agricultural technology. Even just the 1% isn't sustainable. We will need to fix it regardless of whether we "want" to feed 1% or 100%, because it's a massive problem already. The times of Ol' McDonalds self-sustainable farm are long gone. It's a meat factory, and it's taking all of our resources and all of our land, and it simply shouldn't.
Unfortunately, it's very difficult to address this politically because most of the population are still oblivious to how food is actually produced and how damaging it is to the environment. With how few people are actually employed in agriculture these days, it's absolutely amazing how much political support they have for their business.
