And who didn't know this?
Climate
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

How much each change to the atmosphere has warmed the world:

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Ban cow farming
Slash and burn ag is so stupid...
From Wikipedia:
The productivity of the soil following forest removal for farming lasts only a year or two before the fields become infertile and farmers must clear new areas of forest to maintain their income. In 1995, nearly half (48%) of the deforestation in Brazil was attributed to poorer farmers clearing lots under 125 acres (0.51 km2) in size.
They typically grow crops on the land at first, then due to poor soil management it becomes useless for crops so they put cattle on it and burn down more forest to grow more soy or whatever.
Then again. Big picture time.... We're globally releasing enough GHGs that it's equivalent to burning down the entire Amazon rainforest every two months.
Those who trade forest for steak will eventually have neither forests nor steaks.
Unfortunately, it won't be them in most cases. It will be future generations and people in poorer countries that suffer first and the hardest.
Let the future generations eat cake! Heh. Happy cake day!
Have you seen the price of beef? The future is now! ;)
I haven't, but I'm more than happy if the market proofs me wrong. IMO the price can't be high enough if that's what it takes to reduce the demand.
The demand is insatiable, and unmet. Price based demand destruction is only part what were seeing here. Whatever can be made will be sold. We can't supply enough to meet demand so we ration by price.
It's not the victory you probably hope for.
Glad I stopped eating beef years ago. I'm not the problem.
Cows aren't a problem.
People are.
Are you not a person?
