If we can turn the world around and prevent it's collapse from all the damage done to it by boomers and genXers, then yes. If the world Collapses, then no.
The damage is non-reversible, we can only slow it down (enviromentally speaking).
The growing disparity between rich and poor countries will also be a big problem.
And what can "we" do anyway? Millenials don't have a say in anything.
The powers that be are politicians of old age and heads of huge corporations...
