Biodiversity and Environmental Impact

The video discusses the importance of biodiversity for ecosystem stability and the negative impact of human activities, such as population growth and industrialization, on biodiversity. It highlights the challenges of waste management and the effects of land, water, and air pollution, including acid rain. The video also covers the impact of fertilizers on aquatic life and suggests solutions to mitigate pollution, such as using cleaner fuels and catalytic converters.

Why is biodiversity crucial for ecosystem stability?

• It promotes technological advancements.

• It reduces the need for human intervention.

• It ensures ecosystems are more resilient to changes.

• It increases the number of species in an area.

What is a major consequence of increased human population on biodiversity?

• Increased biodiversity

• More stable ecosystems

• Destruction of habitats

• Decreased technological growth

What is a significant source of land pollution?

• Technological advancements

• Increased biodiversity

• Bodily and industrial waste

• Natural disasters

How can pesticides and herbicides affect aquatic life?

• By promoting plant growth

• By causing bioaccumulation in top predators

• By increasing oxygen levels in water

• By reducing water pollution

What is bioaccumulation?

• The reduction of waste in ecosystems

• The increase of oxygen in water

• The process of increasing biodiversity

• The buildup of poisons in top predators

What role do bio-indicators play in assessing water pollution?

• They promote the growth of aquatic plants.

• They reduce the need for chemical testing.

• They help judge the pollution levels of water bodies.

• They increase the oxygen levels in water.

What is a consequence of acid rain on ecosystems?

• Death of plants and aquatic animals

• Neutralization of water bodies

• Increased plant growth

• Improved air quality

How can acid rain be prevented?

• By increasing the use of pesticides

• By using cleaner fuels and catalytic converters

• By reducing water usage

• By promoting deforestation

What are particulates and their effect on the environment?

• Particles that increase oxygen levels

• Particles that promote plant growth

• Tiny particles that reflect sunlight back into space

• Large particles that increase sunlight

What is the primary source of nitrogen oxides contributing to acid rain?

• Natural gas

• Bodily waste

• Industrial waste

• Car emissions
