Biodiversity and Its Importance

The video explores Earth's biodiversity, highlighting its genetic, species, and ecosystem diversity. It discusses the importance of biodiversity, patterns of distribution, and the threats it faces, including mass extinction. Biodiversity hotspots are identified as critical areas for conservation. The video emphasizes the need to protect biodiversity for environmental services, food supply, and potential medical resources.

What is biodiversity primarily concerned with?

• The number of planets in the solar system

• The variety of non-living things on Earth

• Human activities

• Natural disasters

What are biodiversity hotspots?

• Regions with low biodiversity

• Regions with high biodiversity under threat

• Areas with no human habitation

• Places with extreme weather conditions

Why are biodiversity hotspots important for conservation?

• They cover most of the Earth's surface

• They contain a significant portion of Earth's biodiversity

• They are easy to access

• They have no human impact

What human activities threaten biodiversity hotspots like the Amazon?

• Renewable energy projects

• Uncontrolled urbanization

• Sustainable farming

How does biodiversity benefit humans?

• By causing more diseases

• By reducing food supply

• By increasing global temperatures

• By providing environmental services

What is a potential consequence of continued biodiversity loss?

• Longer lifespans

• More natural resources

• Human extinction

• Increased biodiversity

What role does biodiversity play in medicine development?

• It has no role

• It is a barely explored resource

• It decreases the effectiveness of medicines
