All 6 cards in this deck

What term describes methods used to increase the population of an endangered species, such as the white-clawed crayfish?: Conservation.
Give two methods used in animal conservation projects to increase numbers of endangered species.: Controlled breeding programmes and maintaining (protecting) habitats; also reduction in poaching, allowing re-introduction into the wild.
Give two benefits to an ecosystem of conserving animal species.: It maintains the food web and maintains genetic diversity.
How does reforestation affect the composition of the air?: More photosynthesis removes carbon dioxide and releases oxygen, reducing greenhouse gases and global warming.
Give two benefits of reforestation other than changing the composition of the air.: It provides habitats, increasing biodiversity; trees take up water from the soil, preventing erosion and reducing flooding.
True or false? Income from zoos, animal parks and ecotourism can be used to fund conservation projects.: True. Generating income in this way helps pay for conservation of endangered species.
