Human Impact on Ecosystems and Conservation

The video discusses human impacts on Earth's systems: hydrosphere, atmosphere, geosphere, and biosphere. It highlights pollution, resource use, and conservation efforts, using the Florida panther as a case study. Human activities affect water, air, land, and living organisms, showing interconnected effects across systems.

Which of the following is NOT considered one of the four major parts of Earth's systems?

• Biosphere

• Atmosphere

• Lithosphere

• Hydrosphere

What is a major consequence of human activities on the hydrosphere?

• Increased biodiversity

• Scarcity of fresh and clean water

• Improved air quality

• Decreased soil erosion

What is a common source of nonpoint-source pollution?

• Sewage discharge

• Oil spills

• Rainwater runoff

• Factory emissions

Which human activity is a significant contributor to air pollution?

• Using solar panels

• Recycling

• Burning fossil fuels

• Planting trees

How can humans reduce the chance of soil erosion?

• By clear-cutting forests

• By building more roads

• By planting different types of crops

• By overgrazing livestock

What is a potential positive impact of human activity on the biosphere?

• Causing species extinction

• Destroying natural habitats

• Increasing pollution levels

• Controlling overpopulated species

What happens when a habitat is degraded?

• It becomes more biodiverse

• It increases in size

• It can no longer support its organisms

• It becomes a tourist attraction

What was a major factor in the decline of the Florida panther population?

• Increase in prey species

• Climate change

• Urbanization and habitat fragmentation

• Introduction of new predators

What conservation effort helped increase the Florida panther population?

• Building more roads

• Protecting and connecting habitats

• Legalizing hunting

• Introducing new species

What is a current threat to the Florida panther population?

• Lack of food

• Overpopulation

• Disease

• Vehicle collisions
