  2. Ecology provides scientific understanding of living things and their environment; environmentalism is more about conservation and preservation of life on Earth.
  3. Environmentalists are only involved in politics and advocating for protecting nature; ecologists are only involved in scientific investigations of the environment.
  4. Ecologists   study   organisms   in   environments   that   have   been   undisturbed   by   human   activities; environmentalists study the effects of human activities on organisms.
