For most countries around the world, sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 would reduce their energy needs and costs, improve air quality, and help slow climate change, according to a study in Environmental Science & Technology.
This is just false. The biggest source has long been fossil fuel burning, not agriculture, and that remains true even when you include fossil fuel use by agriculture.
On top of that, meat and dairy are only part of agriculture; a big chunk of methane emissions from agriculture come from rice farming.
A huge cut in meat (and dairy) consumption is going to be needed to get to net zero emissions, but it’s not a majority of what is needed. People recommend it strongly in large part because ending meat consumption doesn’t cost people money, so everybody can do it.
Please don’t repeat false claims here.
