3.The definition of an environmentalist is a person who is concerned with protecting the earth's environment, solving environmental problems and preserving natural resources.
4. The human population requires resources to survive and grow, and many of those resources are being removed unsustainably from the environment. The five main threats to biodiversity are habitat loss, pollution, overexploitation, invasive species, and climate change.
5. Sustainability is most often defined as meeting the needs of the present without compromising the ability of future generations to meet theirs. It has three main pillars: economic, environmental, and social. These three pillars are informally referred to as people, planet and profits.
6.A sustainability policy should outline your commitment to practices and standards designed to promote environmentally responsible operations.
7. Biodiversity is usually explored at three levels - genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.
