How does air pollution affect human health?

• It only affects animals, not humans

• It can cause respiratory problems, heart disease, and other health issues.

• It can improve human health

• It has no impact on human health

What are some measures to reduce air pollution?

• Increasing industrial emissions

• Cutting down more trees

• Using public transportation, carpooling, reducing industrial emissions, planting trees, and using clean energy sources

• Using more fossil fuels

Explain the concept of acid rain

• Acid rain is caused by the excessive use of air fresheners in households

• Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.

• Acid rain is a result of excessive consumption of carbonated drinks by the population

• Acid rain is caused by excessive use of sunscreen by humans

What are the main causes of climate change?

• Agricultural practices, urbanization, and waste management

• Nuclear power plants, wind turbines, and hydroelectric dams

• Volcanic eruptions, solar radiation, and ocean currents

• Greenhouse gas emissions, deforestation, and industrial processes

How does deforestation contribute to climate change?

• Reduces the number of trees available to absorb carbon dioxide from the atmosphere.

• Leads to the release of oxygen into the atmosphere.

• Increases the number of trees available to absorb carbon dioxide from the atmosphere.

• Has no impact on the carbon dioxide levels in the atmosphere.

What are the effects of climate change on wildlife?

• Increase in wildlife population

• No impact on migration patterns

• Decreased risk of extinction

• Habitat loss, changes in migration patterns, and increased risk of extinction

Explain the concept of the greenhouse effect

• The greenhouse effect is the process by which radiation from a planet's atmosphere has no impact on the planet's surface temperature.

• The greenhouse effect has no role in climate change and does not affect the Earth's temperature.

• The greenhouse effect is the process by which radiation from a planet's atmosphere cools the planet's surface, causing a decrease in temperature.

• The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

What are the different methods of waste management?

• Recycling, composting, landfill disposal, waste-to-energy facilities

• Burning waste in open fields

• Leaving waste on the streets

• Dumping waste in rivers

How can individuals contribute to effective waste management?

• By throwing waste in the streets

• By using single-use plastic and not recycling

• By burning waste in open areas

• By reducing, reusing, and recycling materials, properly disposing of hazardous waste, and participating in community clean-up efforts.
