The introduction of harmful materials into the environment
What are fossil fuels?
Fossil fuels are a non-renewable source of energy, that release greenhouse gases when burned

What is it called when waste is converted into something new?
Recycling
There is also Reusing which is slightly different
Is climate change natural or caused by humans?
Mainly caused by humans
What is a greenhouse gas and where do they come from?
Gases that increase the temperature of the planet, such as CO2 or Methane
Almost 80% of greenhouse gases are made by burning fossil fuels
Name 2 types of pollution
Water, Air, Light, Noise, Soil, Radioactive, Thermal
What is overfishing
When fish are caught at a faster rate than they can reproduce
What is an alternative to driving that is better for the environment?
Walking, Public transport
What causes climate change?
Human activities such as burning fossil fuels
Is there an alternative to using fossil fuels for energy? Can you name it
Yes, Renewable energy
Or Nuclear energy
What is water pollution?
Contamination of water, this causes negative impacts
Over 3.5 million people each year die because of water pollution
What is deforestation
Destruction of forests by cutting down trees
What are some things you can do to use less water and electricity at home?

What type of energy could people use to release less greenhouse gases?
Renewable
Why is climate change bad?
Climate change threatens life all over the earth, due to direct consequences and then a chain of effects
Eventually climate change will cause all life on earth to go extinct
Why is renewable energy not used more?
It is unpredictable and creates less energy
For it to be efficient would need lots of money to build infrastructure
What is light pollution, why could this be bad?
It is the excessive use of light at night compared to what it would be naturally
It is harmful for animals, disrupts their patterns
The 'Tragedy of the commons' is when people exploit a shared resource for personal gain and eventually destroy the resource for everyone. Can you name an example?
Overfishing, Water, Fast fashion, Traffic
Who is really responsible for climate change and global warming?
