Biodiversity and Environmental Impact

The video explains biodiversity as the variety of species within ecosystems and its importance for stability and human benefits. It highlights the negative impact of human activities, such as population growth and resource consumption, on biodiversity. The video also discusses environmental degradation, pollution, and their effects on ecosystems. Finally, it suggests solutions to mitigate biodiversity loss through changes in attitude and technology.

What is biodiversity?

• The number of people in a city

• The amount of trees in a forest

• The variety of species in an ecosystem

• The number of animals in a zoo

Why is high biodiversity considered beneficial?

• It causes more diseases

• It reduces the number of plants

• It increases the number of predators

• It makes ecosystems more stable

How does biodiversity benefit humans directly?

• By reducing the need for agriculture

• By increasing the number of natural disasters

• Through pollination and medical resources

• By providing more space for cities

What is one major factor contributing to the reduction of biodiversity?

• Decrease in global temperatures

• Increased demand for consumer goods

• Decrease in human population

• Reduction in industrial activities

What is a consequence of using natural resources faster than they can be replaced?

• Increase in biodiversity

• Extinction of species like the western black rhino

• Increase in renewable resources

• Decrease in pollution levels

What is a common result of waste production and pollution?

• Increase in biodiversity

• Improvement in air quality

• Harm to ecosystems and reduction in biodiversity

• Decrease in global temperatures

How can industrial processes affect the air?

• By increasing rainfall

• By releasing harmful chemicals like sulfur dioxide

• By reducing carbon dioxide

• By releasing oxygen

What is one way pollution can indirectly harm organisms?

• By increasing food supply

• By reducing water levels

• By increasing sunlight

• By changing ecosystems

What is a potential solution to environmental issues mentioned in the video?

• Increasing fossil fuel usage

• Implementing new technologies and changing attitudes

• Relying solely on natural processes

• Ignoring the problems

What is the role of greenhouse gases in environmental issues?

• They reduce biodiversity

• They directly harm organisms

• They contribute to global warming

• They increase rainfall
