All this "Save the earth" projects or themes won't make sense if a random asteroid came from nowhere and hit our planet, wiping out everyone. I think our priorities are misplaced. We should be looking at saving each other, avoid pointless wars and survive peacefully.
You're right to an extent, we can save the world by living a peaceful life together with our brothers, neighbors and everyone at large, most problems encountered today were as a result of our individual differences that stirs up conflict amd we should count it a privilege not being struct by a natural epidemic that could cause a massive loss of lives, also we must be conscious of the environment we leave in to make it a better place for a living and the activities we do on it determine the reactions we get from the nature itself either good or bad.
In other words, what you seem to be saying is that the world isn't for itself, right? I mean, the world is a really wonderful thing... the way it all works together, people included or not. But what value is there to having a wonderfully working world?
I mean, doesn't all the value have to do with people's perception of the value of the world? Sure, some of the animals might have a tiny thought for their ability or inability to find food. But isn't it really the people who take deep though on such things?
If there weren't any people, what good is the world? Nobody else cares much about the world at all.
The most ironic thing is that people can't save the world. All they can do is talk about it. And when they talk about it, they base their talk on some things other people told them, even though the other people don't really know what they are talking about.
I wonder who is manipulating the talk, and why?
