When humans die out because of climate change, they may be the biggest and most widespread animal left, thereby inheriting the planet.
‘After humans started migrating out of Africa, the largest land mammals have died out in each territory that humans have spread to. It’s somewhat of a human hallmark, making other species extinct, although we’ve kept cows around for both food and leather. We’ve actually prioritized cows over other species, leading to a 1.5 billion total cow population across the globe. That’s more than cats and dogs combined: there are only 500 to 600 million dogs in the world and about as many cats.
If global warming keeps going at its current pace, Stephen Hawking estimated last year that humanity has about 100 years left to find a new planet to live on and only 1,000 years left on this planet before the heat completely kills all life. Pre human-kind meddling, larger animals simply adapted to climate change. But at this accelerated pace, species go extinct at an astronomical level. Between 24-100 species every day become extinct, and that’s a conservative estimate. Because there are so many cows on the planet, it’s fairly safe to say that even if all humans died out tomorrow all cows would have to do is graze and slowly move north as the planet got hotter. That’s conjecture, sure, but from a strictly numerical standpoint, there’s a good chance that cows will enjoy a very short time at the top of the food chain before the planet becomes completely uninhabitable except for cockroaches….’
