Answer:
Give or take maybe the next 1000 years.
Step-by-step explanation:
We will ultimately go extinct in the next 1000 years due to climate change and water resources. We keep cutting down trees and trees to make all this stuff, when the last tree is cut down we lose oxygen supply and most likely 100% of humans and animals will die. Another is war that can make us go extinct, if we keep going to war and if we all end up launching nukes humanity will cease to exist. Lastly, the same way dinosaurs died, a giant meteor. If a meteor hits earth and its bigger than earth thats another way we may end up dying. So give or take 1000 years.
