Human Activities

Review the graph showing marine fishing rates.If the fishing rate in Asia continues to grow, what will most likely happen as a result?

• The fish population will continue to rise.

• A wide range in ocean temperatures will be seen worldwide.

• The U.S. human population will decline.

• The overfishing will cause an imbalance in marine ecosystems.

Which of these human activities is most likely to cause the excessive growth of phytoplankton in the world's oceans?

• The use of chemical fertilizers that are carried by runoff into rivers

• The logging of old-growth forests, which results in erosion

• The spraying of chemical herbicides that reduce carbon dioxide in the air

• The mining of fossil fuels, which requires digging underground tunnels

If fossil fuel usage were unlimited, what effect would this have on Earth’s biosphere?

• It would create more nutrient-rich soil, which would increase the biodiversity on Earth.

• It would pollute natural habitats, which would decrease the biodiversity on Earth.

• It would add more oxygen to the atmosphere, which would cause plants to increase their rates of photosynthesis.

• It would produce warmer climates, which would cause fewer plants to live in the polar regions.
