I love it! This puts the beauty of the earth and stuffs it into one feeling of tranquility and peace. Great word choice and sentence flow, which varies in appropriate spots.
The only tip I have, in order to keep a feeling of abstract beauty, is to refrain from more literal terms. "In constant search of food and shelter" seems very Nat-Geo documentary sounding, and those two terms could be replaced with "home" and "opportunities". Something like that.
