There's been many years with no wars. However we're still arguing over land and resources. We somehow don't realise the irony of what we're doing, even though we have done it for thousands of years. So my answer is no clue.

In our lifetimes, I think it's safe to asy probably not. Although I think it's worth noting that, even though it doesn't quite seem like it, I think we are making progress towards that goal. Just a little. Will we ever? That I don't know. Historically, I don't think there has been a time where humans have ever been at peace amongst ourselves, and with the planet. We've always been fighting something or someone, and I don't know if the human species, especially with how large we've grown, is really capable of finding peace fully. Still, I hope we do. Maybe, one day, in the far future, we will. And I hope that everyone gains that hope, too, because hope is usually the kickstarter of progress.
