The meaning of Ecology is “the science about all living beings in relation to their environment”. The ecosystem is the complex connections between plants, animals, people, micro-organisms, water, wind, minerals, and so on. The ecological ground rules are:

  • Everything exists in conjunction with each other
  • Everything is a cycle of exchange (there is no final)
  • Nature knows best
  • There are no free lunches
