I think that the preservation of life on our planet is essentially important. Without it, we won't be able to exist. Life is a major concept of our existence, but life isn't eternal definition.
Technical progress gradually reduces some animal species, birds, plants and fishes. However, scientists work on development of more eco-friendly enterprises, treatment plants and filters. It slows down process of extinction to live a little.
In my opinion, our planet will shortly spend all the natural stocks. Population will increase to global scales. Scientists won't be able to prevent this process, but can slow it down. Also huge works on stay or creation of ways to increase Earth life time are conducted now.
But all of this will only delay death of the native planet and  soon or later we should replace the habitat.
