Maintaining Biodiversity Flashcards

All 6 cards in this deck

What is a breeding programme for endangered species?: Breeding a species at risk of extinction in captivity to increase its numbers, then reintroducing individuals to the wild.
Why are field margins and hedgerows reintroduced where farmers grow only one type of crop?: They provide habitats and food for many species, so biodiversity increases.
What is meant by regeneration of a rare habitat?: Restoring a damaged habitat, e.g. by replanting, so that its species can return.
How does recycling resources rather than dumping waste in landfill help biodiversity?: Less land is used for landfill and less pollution is produced, so fewer habitats are destroyed.
True or false? Governments reducing deforestation and carbon dioxide emissions helps to maintain biodiversity.: True. It preserves habitats and limits global warming.
Give one conflicting pressure that can act against maintaining biodiversity.: The need for land or money — e.g. land is wanted for farming or housing, and protection schemes are expensive or cost jobs.
