From user @forkranger on TikTakTok. [continuation of post text] "... In other regions, the grasslands are overgrazed because the number of ruminants is too high. In both cases, grasslands are optimized for meat and dairy production instead of biodiversity. Our World in Data does notes that there is some uncertainty regarding 'rangeland' and how much of that is used for grazing. "Despite this uncertainty, most analyses conclude that nearly half of habitable land is used for agriculture.” The WRI also explains that one-third of all pasture used to be forest. And because the native grasslands are already in use, increased demand for beef and dairy leads to deforestation to create more pasture.

Video clip of showing Neil deGrasse Tyson, American astrophysicist and writer speaking, transcript: Climate change will not make earth uninhabitable. Climate change will make earth a living hell. In fact, I live in New York city where in our harbor we have the statue of liberty and she is holding the declaration of independence in her left arm and her right arm has the torch. The melting ice on land? The ocean level will rise to reach her left elbow. So that takes out all of New York city and basically every other coastal that we've spent tousands of years building since the dawn of civilization. So life will be very very different. So the way I look at it there is people who want to colonize other planets, give us an escape route. We trashed earth, let's move elsewhere and hope we don't trash that. Well, there aren't many places to move. You'll vaporize on Venus, so you're not going to Venus. Mars rotates once every 24 hours. That's kind of interesting. It's tipped on its as earth is, which means it has seasons, it has polar ice caps the way we stil do at this moment, and there is evidence of running water on its surface. So there's a chance we could terraform Mars. My favourite word over the past few decades. You turn something that is not Earth to something that's like Earth. Then you just move there. So here's the catch. If you have the power of geoengineering, to turn Mars into Earth, then you have the power of geoengineering, to turn Earth back into Earth.
