"I’ve crunched the numbers on how much land we would need to support our **current population of 8 billion people** using different foraging and farming regimes. Remember: **the amount of habitable land on Earth** – that’s all our ice- and desert-free land – is **around 100 million km2**, and we currently use half of it – 50 million km2 – for farming. "**To support 8 billion through hunting and foraging we would need 8,000 to 800,000 million km2 of viable land. That’s 100 to 10,000 times the amount of land we have on Earth**. That’s also ignoring the inconvenient reality that we’d wipe out all mammals along the way.
