What is net zero?

• A state where the amount of greenhouse gases emitted is equal to the amount removed from the atmosphere

• A financial term referring to zero net profit

• A mathematical term for zero

• A type of energy source

Nuclear power is considered by some to help us reach net zero because:

• It produces no greenhouse gas emissions during operation.

• It is the cheapest form of energy.

• It is the most abundant energy source.

• It requires no safety measures.

Nuclear power is controversial because:

• It is a renewable energy source.

• It produces radioactive waste.

• It is the cheapest form of energy.

• It has no environmental impact.

The greenhouse effect is a phenomenon that involves the trapping of heat in the Earth's atmosphere. Is it considered a good thing?

• Yes, it is essential for maintaining Earth's temperature.

• No, it leads to global warming.

• It has no impact on Earth's climate.

• It is only beneficial for plant growth.

Afforestation helps combat climate change because it:

• Increases carbon dioxide levels

• Reduces greenhouse gases

• Destroys natural habitats

• Increases soil erosion

How could we reduce emissions of methane?

• By increasing the use of renewable energy sources

• By reducing the consumption of fossil fuels

• By improving waste management practices

• All of the above
