Understanding Our Environment

What is pollution and how does it affect our health?

• Pollution is the introduction of harmful substances into the environment, negatively impacting health by causing various diseases.

• Pollution is a natural process that improves health.

• Pollution only affects animals and not humans.

• Pollution is the absence of clean air and water.

Name four types of pollution and give an example of each.

• Noise Pollution: Loud music from concerts

• Thermal Pollution: Heating water in swimming pools

• Light Pollution: Excessive street lighting

• 1. Air Pollution: Smog from vehicle emissions; 2. Water Pollution: Oil spills; 3. Soil Pollution: Pesticide contamination. 4.Noise Pollution: loud noise of machines

How does air pollution impact the environment?

• Air pollution solely benefits urban development and infrastructure.

• Air pollution has no effect on wildlife or habitats.

• Air pollution harms ecosystems, reduces biodiversity, and contributes to climate change.

• Air pollution improves air quality and promotes plant growth.

What are some common sources of water pollution?

• Common sources of water pollution include industrial discharges, agricultural runoff, sewage and wastewater, oil spills, and plastic waste.

• Desalination plants

• Rainwater collection systems

• Natural mineral springs

Why is recycling important for the environment?

• Recycling depletes natural resources.

• Recycling has no impact on pollution levels.

• Recycling is important for the environment because it conserves resources, reduces pollution, and minimizes waste.

• Recycling increases waste production.

List three materials that can be recycled.

• fabric

• metal

• paper, glass, plastic

• wood

How can we reduce plastic waste in our daily lives?

• Use more plastic bags for shopping.

• Buy products with excessive plastic packaging.

• Throw all plastics in the trash without sorting.

• Adopt reusable items and reduce single-use plastics.

What is the greenhouse effect?

• The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

• The greenhouse effect refers to the increase in Earth's surface temperature due to volcanic activity.

• The greenhouse effect is caused by the depletion of ozone in the stratosphere.

• The greenhouse effect is the cooling of Earth's surface due to the reflection of sunlight.

How do greenhouse gases contribute to global warming?

• Greenhouse gases contribute to global warming by trapping heat in the atmosphere, preventing it from escaping into space.

• Greenhouse gases cool the Earth by reflecting sunlight away.

• Greenhouse gases only affect the weather in specific regions.

• Greenhouse gases have no effect on the Earth's temperature.

What are some effects of global warming on wildlife?

• Effects of global warming on wildlife include habitat loss, altered migration patterns, changes in breeding seasons, and increased disease vulnerability.

• More stable weather patterns

• Decreased competition for resources

• Increased food availability for all species
