Environmental laws regulate the impact of human activities on the environment.
Environmental law covers a broad range of activities that affect air, water, land, flora or fauna.  It includes laws that relate to:
• Protection of animals and plants • Planning for the use and development of land • Mining, exploration and extractive industries • Forestry • Pollution • Fisheries • Land and fire management • Agriculture and farming • Waste management • Climate change and emissions • Water resource management (lakes, wetlands, rivers and oceans) • Chemicals and pesticides • Weeds and invasive species • Marine life
The main objective of Environmental Law is to assure that the environment be protected against both public and private actions that failed to take account of costs or harms inflicted on the eco-system.
It ranges from widespread regulatory systems developed by the Environmental Protection Agency to generally accepted common law principles dealing with liability for the release of substances into the environment.
