We live within the environment. So that directly relates with our survival, our life. So through that way, more concern of well being of humanity, then naturally concerned about environment.
All of us living in today's world are facing an enormous crisis - arguably the greatest that humanity has ever faced - in the form of man-made global warming; one can't be neutral at such a moment. It's like claiming to be neutral if you're living in Germany in 1933.
Humanity can live without science, it can live without bread, but it cannot live without beauty. Without beauty, there would be nothing left to do in this life. Here the secret lies. Here lies the entire story.
Every idea has to become broad till it covers the whole of this world, every aspiration must go on increasing till it has engulfed the whole of humanity, nay, the whole of life, within its scope.
The intelligible forms of ancient poets, The fair humanities of old religion, The power, the beauty, and the majesty That had their haunts in dale or piny mountain, Or forest by slow stream, or pebbly spring, Or chasms and watery depths, all these have vanished; They live no longer in the faith of reason.
