Study Notes
Biodiversity
- Biodiversity refers to the variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole.
Ecosystem Services
- Provisioning services: providing food, water, and other resources
- Regulating services: maintaining climate, air and water quality, and soil health
- Cultural services: providing recreational, spiritual, and educational benefits
Conservation
- Conservation involves the protection and preservation of natural habitats, ecosystems, and species to maintain their diversity and integrity.
Importance of Biodiversity
- Biodiversity is important for humans as it provides essential services, ensures food security, and maintains human health.
Regulating Services
- Regulating services include climate regulation, flood and drought prevention, and pollination.
Climate Change
- The primary cause of Climate Change is the increasing levels of greenhouse gases in the atmosphere, mainly due to human activities.
Natural Threats to Species Survival
- Habitat destruction, pollution, climate change, and overexploitation are natural threats to species survival.
- NOT a natural threat: alien species invasion.
Greenhouse Gases
- Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, trap heat in the atmosphere and maintain the Earth's temperature.
Methane Emissions
- Methane emissions are caused by the decomposition of organic matter in landfills, agriculture, and natural sources.
Industry Sector Emissions
- The agriculture sector emits Carbon Dioxide and Nitrous Oxide.
