Everything has an interrelating function, a purpose of equal importance. Some call this understanding Deep Ecology. I like the principles of Deep Ecology, and not only because it makes me care for the environment and the future of the planet. It also gives meaning to my life. For some, meaning is not a problem.
Mothers often live for their kids.
Corporation types live for their companies, patriots live, and often die for their countries. But for many, finding the meaning of their existence is difficult. A good way to show the interconnectedness of all things in our environment is through the Gaia hypothesis . When the U.S. space program prepared its Mars probe, one of its objectives was to find whether there is life on Mars. They hired a British scientist named Lovelock to design a detection system.
