Understanding Our Environment

What are some major effects of climate change?

• Decreased global temperatures

• Increased availability of freshwater

• Enhanced crop yields worldwide

• Major effects of climate change include rising sea levels, increased frequency of extreme weather events, loss of biodiversity, and impacts on agriculture and human health.

How does air pollution affect human health?

• Air pollution only affects animals, not humans.

• Air pollution has no effect on human health.

• Air pollution negatively impacts human health by causing respiratory and cardiovascular diseases, reducing lung function, and increasing the risk of cancer.

• Air pollution improves lung function and overall health.

What is biodiversity and why is it important?

• Biodiversity is unimportant and has no effect on human life.

• Biodiversity is the study of animal behavior and its impact on ecosystems.

• Biodiversity refers to the number of species in a single habitat.

• Biodiversity is the variety of life on Earth, and it is important for ecosystem health, resilience, and services.

Name three sustainable practices individuals can adopt.

• Waste more food

• Drive alone everywhere

• Reduce waste, conserve water, use public transportation.

• Increase plastic use

What are the main causes of water pollution?

• Natural evaporation

• Water temperature changes

• Rainfall patterns

• Industrial waste, agricultural runoff, sewage and wastewater, plastic waste, oil spills.

How do ecosystems contribute to the environment?

• Ecosystems are solely responsible for human health.

• Ecosystems provide essential services that support life, regulate climate, and maintain biodiversity.

• Ecosystems only provide food for animals.

• Ecosystems have no impact on climate change.

What is the significance of conserving natural resources?

• Conserving natural resources is significant for ecological balance, sustainability, and future generations.

• Conserving natural resources has no impact on climate change.

• Natural resources should be consumed as quickly as possible.

• Conserving natural resources is only important for economic growth.

How does deforestation impact climate change?

• Deforestation decreases carbon dioxide levels, helping to cool the planet.

• Deforestation increases oxygen levels, promoting a healthier atmosphere.

• Deforestation has no effect on climate change or local weather patterns.

• Deforestation increases carbon dioxide levels, contributing to global warming and disrupting local climates.

What role do renewable energy sources play in sustainability?

• Renewable energy sources are not cost-effective and hinder economic growth.

• Renewable energy sources are essential for sustainability as they provide clean, infinite energy, reduce environmental impact, and enhance energy security.

• They primarily contribute to increased pollution and waste.

• Renewable energy sources are limited and deplete over time.

Why is it important to protect endangered species?

• It is important to protect endangered species to maintain biodiversity and ecosystem health.

• To increase the population of invasive species.

• To promote hunting and fishing activities.

• To reduce the number of animal species in the wild.
