what is biodiversity important for
food, potential foods, industrial MATERIALS, new medicines, human well-being (STABLE ECOSYSTEMS)
what is causing animals to become extinct and what does this lead to
man destroying their habitats
decrease in biodiversity
how are habitats being destroyed
land being used for building, industry, agriculture and landfill
How can biodiversity and endangered species be protected? (6)
CITES, SSSI, Captive breeding programmes, National parks, seed/sperm banks, local biodiversity action plans
CITES
convention on the international trade in endangered species
(Prevents trade in endangered species)
SSSI
Sites of special scientific interest
Legally protected sites protected because they contain rare species or habitats
Captive breeding programs (e.g zoos)
Increasing numbers of rare species through breeding programmes then releasing them back into the wild
Seed banks
A way of Maintaining genetic biodiversity in case a species of plant or animal become extinct
why is a stable ecosystem important
regulate atmosphere, water supply, nutrient cycles and provide fertile soil
alien species
An animal or plant that has been introduced into a country that it does not originate from
what problems can invasive species cause
they can grow faster than native species and upset the natural ecosystem
