Understanding Environmental Issues

What are the main causes of biodiversity loss?

• Natural selection

• Seasonal changes

• Urban development

• Habitat destruction, climate change, pollution, overexploitation, and invasive species.

How does renewable energy contribute to reducing carbon emissions?

• Renewable energy contributes to carbon emissions by using non-renewable resources.

• Renewable energy increases carbon emissions by relying on fossil fuels.

• Renewable energy reduces carbon emissions by providing cleaner alternatives to fossil fuels, which do not emit greenhouse gases during electricity generation.

• Renewable energy has no impact on carbon emissions during production.

What is the impact of plastic pollution on marine life?

• Plastic pollution improves marine life by providing new habitats.

• Plastic pollution has no effect on marine ecosystems.

• Marine life thrives due to the presence of plastic materials.

• Plastic pollution harms marine life by causing ingestion, entanglement, and habitat disruption.

Name three renewable energy sources and their benefits.

• 1. Solar Energy: Reduces electricity bills and is abundant. 2. Wind Energy: Lowers greenhouse gas emissions and is cost-effective. 3. Hydroelectric Power: Provides reliable energy and helps with flood control.

• Geothermal Energy: Limited to specific locations and has high initial costs.

• Fossil Fuels: Contributes to air pollution and is non-renewable.

• Nuclear Energy: Produces large amounts of waste and is expensive.

How does deforestation contribute to biodiversity loss?

• Deforestation contributes to biodiversity loss by destroying habitats, leading to species extinction and disrupting ecosystems.

• Deforestation has no impact on species populations.

• Deforestation increases biodiversity by creating new habitats.

• Deforestation helps maintain ecosystem balance.

What are the health effects of air pollution on humans?

• Air pollution only affects animals, not humans.

• Air pollution has no impact on human health.

• Air pollution causes respiratory diseases, cardiovascular problems, and can lead to premature death.

• Air pollution improves lung function and overall health.

Explain the concept of ecological footprint.

• The ecological footprint measures the number of species in an ecosystem.

• The ecological footprint is a method to calculate the average temperature of the Earth.

• The ecological footprint quantifies the demand on Earth's ecosystems and compares it to the planet's ability to regenerate resources.

• The ecological footprint refers to the total area of land required for urban development.

What role do fossil fuels play in pollution?

• Fossil fuels have no impact on climate change or air quality.

• Fossil fuels are a renewable energy source that reduces pollution.

• Fossil fuels are primarily used for water purification processes.

• Fossil fuels contribute to air pollution and environmental degradation through emissions and spills.

How can individuals help reduce pollution in their communities?

• Ignore recycling programs

• Drive more frequently

• Use public transport, recycle, conserve energy, reduce waste, and participate in clean-up events.

• Use disposable products

What are the long-term effects of climate change on biodiversity?

• Increased rainfall leading to more habitats

• Long-term effects of climate change on biodiversity include habitat loss, increased extinction rates, shifts in species distribution, and altered ecosystem dynamics.

• Stable ecosystems unaffected by temperature changes

• Higher biodiversity due to climate adaptation
