Understanding Biodiversity and Ecosystems

The video explains biodiversity as the variety of life on Earth, highlighting its importance for healthy ecosystems and human benefits like food, water, and medicine. It uses the British coastline as a case study to show how kelp forests support marine life and combat climate change. The video discusses threats to biodiversity, such as habitat conversion and overfishing, and emphasizes the need for sustainable practices to protect our planet. Viewers are encouraged to make small changes to help preserve biodiversity.

What does biodiversity encompass?

• Only animals

• Only plants

• All life forms on Earth

• Only marine life

Why is biodiversity crucial for Earth's health?

• It helps ecosystems cope with change

• It provides more food options

• It reduces the need for conservation

• It increases the number of species

What is a key feature of a healthy ecosystem?

• Lack of biodiversity

• Dependence on a single species

• Ability to cope with change

• Isolation from other ecosystems

What is the relationship between biodiversity and human well-being?

• Biodiversity is harmful to human health

• Biodiversity has no effect on humans

• Biodiversity supports resources like food and medicine

• Biodiversity only benefits animals

What role do kelp forests play in marine ecosystems?

• They provide shelter and protect shores

• They are only a food source

• They are used solely for decoration

• They have no significant role

What is the impact of kelp forests on climate change?

• They only affect local weather

• They have no impact

• They increase carbon emissions

• They capture carbon and slow climate change

What is one consequence of removing kelp from coastal ecosystems?

• Collapse of the ecosystem

• Increased fish population

• More recreational areas

• Improved water quality

What human activities are contributing to biodiversity loss?

• Planting more trees

• Converting habitats into urban areas

• Reducing waste

• Protecting green spaces

What is one of the threats to biodiversity mentioned in the video?

• Overpopulation of species

• Harvesting kelp for fertilizer

• Increased rainfall

• Natural disasters

How can individuals help protect biodiversity?

• By ignoring environmental issues

• By reducing waste and eating sustainably

• By avoiding green spaces

• By using more plastic products
