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.
Explore the concept of biodiversity, its importance, and the ecosystem services provided by nature. Learn about the variety of life, the traits within and between species, and the impact of changes on ecosystems. Discover how the loss of biodiversity can affect the ability of nature to provide products like food, medicines, timber, and freshwater.
