Understanding Biodiversity and Its Importance
- Biodiversity refers to the variety of life on Earth, including all living things, from genes to ecosystems.
- Biodiversity is essential to the wellbeing of the planet and includes human diversity and cultural links to the places where we live.
- Biodiversity is valuable for both utilitarian and intrinsic reasons, including providing basic human needs, ecosystem services, potential benefits, cultural and spiritual values, and inherent worth.
- The different values placed on biodiversity can influence conservation decisions.
- Human activities, such as habitat loss, unsustainable resource use, invasive species, pollution, and climate change, pose direct threats to biodiversity.
- The underlying causes of biodiversity loss are complex and stem from many interrelated factors, such as a growing human population and overconsumption.
- The conservation efforts of the last decades have made a significant difference in the state of biodiversity today, including the establishment of over 100,000 protected areas.
- Other types of conservation actions, such as restoration, reintroduction, and the control of invasive species, have had positive impacts.
- Environmental policies at local, regional, and global scales have improved to support conservation efforts.
- Lifestyle choices of individuals and communities can have a large effect on their impacts on biodiversity and the environment.
- Knowledge can help change the direction and shape of human impacts on biodiversity.
