Sustainability and Environmental Impact

The video explores human impact on the environment, focusing on sustainability, resource management, and the role of technology. It discusses renewable and non-renewable resources, the greenhouse effect, and global warming. The impact of agricultural, alternative, and industrial technologies on sustainability is examined, highlighting both benefits and challenges. The video also addresses human effects on biodiversity and ecosystems, emphasizing the importance of balancing human needs with environmental preservation.

What is the primary goal of living sustainably?

• To maximize human resource consumption

• To balance human needs with Earth's resources and other species

• To eliminate all carbon emissions

• To focus solely on renewable resources

Which of the following is a renewable resource?

• Coal

• Oil

• Sunlight

• Plastic

How does technology contribute to sustainability?

• By eliminating the need for renewable resources

• By increasing pollution without any benefits

• By only consuming more resources

• By providing solutions like cleaner energy and waste management

What is a major benefit of agricultural technology?

• It decreases the need for irrigation

• It reduces the need for fertilizers

• It increases food productivity and speed

• It eliminates the use of fossil fuels

What is a downside of using fertilizers in agriculture?

• They are too expensive to produce

• They create excess nitrogen, altering soil chemistry

• They completely eliminate soil erosion

• They are not effective in increasing food productivity

What is the main goal of alternative technology?

• To increase fossil fuel consumption

• To focus solely on nuclear energy

• To provide clean energy with minimal atmospheric impact

• To eliminate the need for any form of energy

What is a significant drawback of industrial technology?

• It completely eliminates greenhouse gases

• It produces chlorofluorocarbons that deplete the ozone layer

• It relies heavily on renewable resources

• It has no impact on the environment

What is the greenhouse effect?

• A phenomenon that decreases Earth's temperature

• A method to cool the Earth by releasing gases

• A way to eliminate all carbon emissions

• A process where gases trap heat in the atmosphere, warming the Earth

How do invasive species affect biodiversity?

• They always improve the ecosystem's health

• They enhance the native species' growth

• They have no impact on the ecosystem

• They can harm native species by disrupting ecosystems

What is a consequence of increased greenhouse gases?

• Complete elimination of the ozone layer

• No change in Earth's temperature

• Increased Earth's temperature due to trapped heat

• Decreased Earth's temperature
