GLOBAL WARMING + MAINTAINING BIODIVERSITY

The disappearance of dinosaurs millions of years ago is an example of?

• sustainability

• species diversity

• extinction

• bad luck

The loss of a natural habitat is called

• Habitat development

• biodiversity

• Pollution

• Habitat destruction

Why is biodiversity decreasing?

• Loss of habitats

• Government protection programmes

• Hedgerows are being introduced

• Disruption to food chains

Which of these programmes would NOT help to increase biodiversity?

• Introducing hedgerows between fields

• Endangered species breeding programmes

• Clearing more land to make landfill sites

• Protecting rare habitats

Why are some people opposed to protecting rare habitats e.g. peat bogs?

• It slows down development, the land could be used for more housing

• They don't want to increase biodiversity

• These programmes decrease biodiversity

• There are already enough habitats

Why do some people NOT want limits put on deforestation?

• It will reduce biodiversity

• Putting limits on deforestation is ethically wrong

• It could put their livelihood in danger, for example if they are employed to cut down trees

• It could increase global warming

How could governments decrease land pollution from landfill sites?

• Encourage people to recycle

• Pay people to relocate

• Put limits on deforestation

• Introduce endangered species breeding programmes

Which of these is a greenhouse gas?

• Oxygen

• Nitrogen

• Methane

• Helium

Define the term ‘global warming’

• a gradual decrease in the overall temperature of the earth's atmosphere attributed to the gas effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

• a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, nitrogen and other pollutants

• a gradual increase in the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

• a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

• rapid increase in CO2 then gradual decrease

• CO2 increasing at a constant rate

• constant levels of CO2 then rapid increase
