It’s impossible to give a definitive numerical answer, but it’s likely to be far higher than the impact of any other species. No other animal changes its environment as much as we do, and our activities have knock-on effects that impact thousands upon thousands of other species.
According to a paper published in 2014, extinction rates are 1,000 times higher than they would be if we weren’t around. Take a look at the UK, for example. Thousands of years ago, the land was covered in thick forest, and bears, wolves, lynxes and even woolly mammoths roamed the land. We stripped out the trees, hunted the animals, and turned natural landscapes into farms and concrete jungles.
