Study Notes
- Biodiversity is a critical concept in ecology with local and global significance.
- Scientists measure biodiversity at genetic, species, or ecosystem levels.
- Global biodiversity is high in tropical regions like rainforests, while local biodiversity can be low.
- Biodiversity is dynamic, influenced by factors like climate change and human activities.
- There have been five major extinction events in Earth's history, and we're currently experiencing the sixth (Holocene extinction).
- Human activities contribute to biodiversity loss through introduced species, hybridization, over-harvesting, and climate change.
- Humans are responsible for a significant portion of the current extinction events.
- The loss of biodiversity could lead to catastrophic consequences, such as the loss of food crops and ecosystem services.
- Actions to protect and increase biodiversity include managing land, growing multiple crops, and creating urban habitats for other species.
- A healthy biodiverse ecosystem provides essential services like pollination and waste decomposition.
- We need to act collectively to protect biodiversity on both local and global scales.
