ITIS Majorana Brindisi Chemistry course The effects of human activity on the ecosystem Teacher Gioacchino Margarito
Nature as an inseparable whole Nature is not only the species that inhabit particular ecosystems. It is an ever-changing system in which these organisms are connected with each other.
Ecosystem The Earth behaves as a single self-regulating system that includes physical, chemical, biological and human components. James Lovelock Water cycle

Flooding of a creek due to heavy monsoonal rain and high tide in Darwin, Northern Territory, Australia.
