Environmental conservation includes taking care of the air and the earth's atmosphere, animal and plant life , humans and cultural development, and the planet's water. It shares a lot of interests with human rights, because keeping underprivileged populations healthy and thriving has a lot to do with preserving the earth. Conservation can be as little as planting a tree and maintaining it or as big as saving a species of whales. The main idea is that any progress is good progress, no matter the size.
