The impact of human activities on biogeochemical cycles.

Given:

Human activities alter the biogeochemical cycles.

Introduction:

A biogeochemical cycle can be defined as a pathway by which chemical elements and compounds flow through biotic (biosphere – living components) and abiotic (lithosphere, atmosphere, and hydrosphere – nonliving components) compartments of the Earth. For example, carbon cycle, nitrogen cycle, oxygen cycle, water cycle, phosphorus cycle, and sulfur cycle.
