Answer 1

Here are answers to your questions based on general knowledge about human impact on the environment and the themes often discussed in related videos:

1. Why was there a large increase in the human population after the Industrial Revolution?

   • The increase in the human population after the Industrial Revolution was primarily due to advances in technology, agriculture, and medicine, which improved food production, healthcare, and living conditions, leading to lower mortality rates and higher birth rates.

2. What is one problem caused by a large human population?

   • One problem caused by a large human population is increased resource consumption, which can lead to depletion of natural resources and environmental degradation.

3. What is an example of humans over-hunting an animal to extinction?

   • The passenger pigeon is a well-known example of a species that was driven to extinction due to over-hunting in the late 19th century.

4. How did humans help prevent bison from being hunted to extinction?

   • Humans helped prevent bison from being hunted to extinction through conservation efforts, such as establishing protected areas, implementing hunting regulations, and breeding programs.

5. What was the impact when humans diverted rivers flowing into the Aral Sea and used the water to irrigate farmland?

   • The diversion of rivers flowing into the Aral Sea led to significant shrinkage of the sea, resulting in loss of biodiversity, collapse of local fishing industries, and negative impacts on the regional climate.

6. What is one problem, discussed in the video, with humans using oil as an energy source?

   • One problem with using oil as an energy source is that it contributes to pollution and greenhouse gas emissions, which exacerbate climate change.

7. What are some alternatives to using oil and fossil fuels as an energy source?

   • Alternatives include renewable energy sources such as solar power, wind energy, hydroelectric power, and geothermal energy.

8. What types of items can be recycled?

   • Common items that can be recycled include paper, cardboard, glass bottles, aluminum cans, and certain plastics.

9. Explain ways in which scientists and engineers are helping to protect our planet?

   • Scientists and engineers are helping to protect the planet by developing sustainable technologies, conducting research on climate change, creating renewable energy systems, and implementing conservation strategies.

10. What is an example of something you can do to help preserve our resource of fresh water?

    • One way to help preserve fresh water is to reduce water usage by taking shorter showers, fixing leaks, and using water-efficient appliances.

11. What is one type of scientist that helps save our planet and what do they do?

    • Environmental scientists work to understand and mitigate human impacts on the environment, conducting research, analyzing data, and developing policies for sustainability.

12. How much water does Adam use every year if taking a 10 minute shower a day?

    • The calculation would depend on the flow rate of the showerhead. If a shower uses about 10 liters per minute, then:
      • 10 minutes/day * 10 liters/minute = 100 liters/day
      • 100 liters/day * 365 days = 36,500 liters/year. However, based on the provided options and typical household water use, "14,610 L" is the most plausible estimated answer if accounting for a lower usage or shorter bath times.

Please ensure that the answers are validated against the video for accuracy as some may depend on specific details presented.
