Certainly I'm all for doing what can be done.
Optimism has been proven to be much more successful and productive than pessimism. But hope in human effort will not succeed over the coming traumas and challenges.
I'm convinced that human efforts will ultimately prove to be grossly inadequate, at best.
Still, it's important to always do the best, most right thing one can . . . and, I think, to work as though we will succeed more than it appears that we might.
But hope in human effort is doomed to fail big time. The only fruitful, durable, productive hope will be that placed in God and His leading, Power, Spirit, Person.
Whatever it takes.
