How do protected areas help conserve forests?
They restrict activities that damage forests.
What do tree-removal quotas limit?
The number of trees that may be removed.
How does replanting help conserve forests?
It replaces harvested trees so the forest can continue to grow.
How does education support forest conservation?
It encourages people to understand the effects of forest loss and support practices that allow forests to persist.
How can habitat destruction and degradation cause populations and biodiversity to decline?
They reduce the places where organisms can live, feed and reproduce.
How does protecting rare habitats help prevent damage to them?
It limits damaging activities.
What is the aim of regenerating damaged habitats?
To help them recover and support their characteristic communities again.
How does removing field margins and hedgerows affect agricultural areas growing a single crop?
It reduces habitat variety.
What three resources can reintroduced field margins and hedgerows provide for organisms?
Food, shelter and breeding sites.
How can hedgerows help organisms move between habitats?
They connect areas of habitat.
How does burning fossil fuels affect atmospheric carbon dioxide?
It releases carbon dioxide, increasing its concentration in the atmosphere.
How does carbon dioxide contribute to climate change?
It contributes to the greenhouse effect.
How can climate change affect species’ habitats?
It can alter habitats and the conditions species need to survive.
How can climate change reduce biodiversity when species cannot adapt or move?
Those species may decline, reducing biodiversity.
Why can governments reduce carbon dioxide emissions to protect ecosystems?
To limit their contribution to further climate change and its effects on ecosystems.
What is recycling?
Processing discarded materials so they can be used again rather than sent to landfill.
How can recycling help protect biodiversity through its effect on landfill?
Less waste needs landfill, reducing land use and potential habitat damage or pollution.
How can recycling help protect biodiversity through its effect on raw materials?
It reduces demand for newly extracted raw materials, limiting habitat damage caused by obtaining them.
