The document defines an ecosystem as including all living and non-living elements in an area along with their relationships. It describes the biotope/physical environment and biocenosis/living things. Relationships between elements include those within and between species, as well as trophic levels with organisms grouped by their food source. Ecosystems are classified as natural without human intervention or humanized with human impacts such as pollution, loss of biodiversity, fires, and deforestation. The document advocates sustainable development, water and energy saving, recycling, and respecting nature.
