Increased environmental awareness & Eco-travel destinations have begun to emerge

When our planet started to exist, only plants and animals inhabit our world. We humans would wait millions of years to begin our evolution and eventually emerge as the supreme and most dominant species in our territory. It would take a combination of natural calamity (asteroid impact killing all dinosaurs) and a rational mind (that which sets us apart from other life forms) to seal our fate as rulers of the earth.
