The Sixth Extinction: Human Impact on Earth's Biodiversity

The video discusses the 6th extinction, a human-caused mass extinction event. It highlights four major causes: climate change, industrial agriculture, pollution, and overhunting. Human activities like fossil fuel consumption, monocropping, and poaching are driving species to extinction. The video emphasizes the need for urgent action to reverse these trends and protect biodiversity.

What is the primary cause of the 6th extinction according to scientists?

• Volcanic eruptions

• Alien invasion

• Human activity

• Natural disasters

How does human-induced climate change contribute to the 6th extinction?

• By increasing rainfall

• By reducing sunlight

• By cooling the planet

• By warming the planet to unsustainable temperatures

What is a major environmental issue caused by monocropping?

• Reduction in pesticide use

• Depletion of soil nutrients

• Improved water quality

• Increased biodiversity

What is a significant consequence of plastic pollution in the oceans?

• Increased fish populations

• More coral reefs

• Cleaner water

• Toxic seafood for humans

Which practice is an example of overhunting?

• Building dams

• Recycling waste

• Poaching endangered species

• Planting trees

What is one of the effects of overfishing?

• Increased fish diversity

• Decreased fish populations

• More marine habitats

• Cleaner oceans

What is a potential solution to reverse the trends of the 6th extinction?

• Ignoring the problem

• Increasing fossil fuel use

• Changing human relationships with nature

• Continuing current practices
