Pollution
What is Pollution?
Pollution is a harmful change to the environment caused by contaminants
How can poor farming practices negatively impact the environment?
They can damage soil, water, air quality, biodiversity and food quality
Why are fossil fuels considered non-renewable resources?
They are used faster than they can naturally be replaced
Why are rain forests important for Earth's atmosphere?
They remove carbon dioxide from the air and release oxygen
What is the greenhouse effect?
The greenhouse effect happens when gases in Earth's atmosphere trap heat and keep the planet warm
Which parts of an ecosystem can pollution affect?
Pollution can affect the air, water, and soil
How can clearing land for agriculture impact wildlife?
It destroys habitats and forces many animal species to leave or die out
What harmful gases are released when petrol is burned?
Nitrous oxides, carbon monoxide, and carbon dioxide are released
Why does cutting down forests contribute to climate change?
Fewer trees means less carbon dioxide is absorbed from the atmosphere
Which three greenhouse gases are mentioned in the slides?
Water vapor, carbon dioxide, and methane
What is one major cause of air pollution in large cities?
Car exhaust and factory smoke are major causes of air pollution in large cities.
How can too much farming hurt the soil?
It can remove nutrients from the soil and make it less fertile over time
How can burning fossil fuels affect animals in the Arctic?
It increases global warming, which melts sea ice and destroys habitats
How can deforestation affect the water cycle?
Fewer trees release less water vapor into the air which can reduce rainfall
How can climate change affect animal migration patterns?
Changing temperatures can force animals to move to new habitats to survive
How can pollution contribute to climate change?
Pollution releases greenhouse gases like carbon dioxide that trap heat in Earth's atmosphere
How do pesticides and fertilizers impact the environment?
Why does coal burning cause major environmental damage?
Burning coal releases large amounts of carbon dioxide and air pollution
Why is deforestation harmful to indigenous communities?
Why does climate change increase the risk of wildfires?
Hotter temperatures and droughts dry out forests and grasslands, making fires spread more easily
How does plastic pollution harm ocean animals?
Many animals accidentally eat plastic or get trapped in it causing injuries and even death
How can raising large numbers of livestock affect the environment?
Livestock produce methane gas, which contributes to global warming
How can using public transportation help the environment?
It reduces the amount of fossil fuels burned by individual cars
How can deforestation affect air quality?
Fewer trees means less air is clean and more pollution stays in our atmosphere
How can climate change impact food production?
