There are many practical applications of ecology in conservation biology, wetland management, natural resource management (agriculture, forestry, fisheries), city planning (urban ecology), community health, economics, and applied science. It provides a framework for understanding and researching human social interaction.
Ecology starts many powerful philosophical and political movements - including the conservation movement, wellness movement, environmental movement, and ecology movement we know today. When these are combined with peace movements and the Six Principles, they are called green movements. In general, these put ecosystem health first on a list of human moral and political priorities, as the way to achieve better human health and social harmony, and better economics.
People with these beliefs are called political ecologists. Some have organized into the Green Parties, but there are actually political ecologists in most political parties. They very often use arguments from ecology to advance policy, especially forest policy and energy policy.
Also, ecology means that it is the branch of biology dealing with the relations and interactions between organisms and their environment, including other organisms.
