Yes it would be great if humanity just used resources at the rate the earth can produce them. But we don't. We use way more.
At the current rate, by August 1 we consume a year's worth of Earth's resources. This would be OK if we had 1.75 Earths - but we don't.
What's worse is that they've also calculated the Earth Overshoot day, and how many earths we'd need, based on the consumption of each country.
If everyone consumed like Australians, we'd need 4.7 Earths (our overshoot day would be 5 April). For the USA it's 5 Earths (an overshoot day of 14 March).
