7.3.5-6 - Global Warming & Maintaining Biodiversity

What is causing global warming?

The increase in levels of greenhouse gases e.g. carbon dioxide and methane, causing the temperature on Earth to increase.

State the consequences of global warming.

• Rising sea levels.

• Melting polar ice caps.

• Changing weather patterns.

• Migration of animals to find suitable habitats.

• Tropical diseases becoming more common.

• Extinction of species.

Describe the steps taken to maintain biodiversity.

• Breeding programs for endangered species.

• Protection and rebuilding habitats.

• Replanting field margins and hedgerows.

• Reduce deforestation.

• Reduce carbon dioxide emissions.

• Recycling rather than disposing in landfills.

What is the purpose of replanting hedgerows and field margins?

There is higher biodiversity in the margins than the fields that they surround.
