Global biodiversity
What is biodiversity?
different kinds of organisms in a given area
how to measure
count total number of species in a area
how many kinds of species
closer to the Equator the more species
in the sea?
many species of fish and corals
endemic species
species that only live in that area
these area's are called "hotspots"
ecosystems
communities of living things and their environments
genetic diversity
how many different genes there are in a area
pro's:better resistant to diseases and species can better adapt to environments
connections between species: all species depend on eachother for survival if one goes extinct the others wil expierince the effects of this
importance for mankind
oxygon food clothes medicine fertile soil prevention floods
medicin:many medicin are made from plants and there are still people researching every species
natural process
extinction and evolution are a natural process but because human activity this process is going to fast because species do not get time to evolve before going extinct
habitats getting destroyed
species that survive have less breeding partners
how?:by human activity and introduction af new species
not only plants and animals
fungi are also effected by these changes in biodiversity habitats and ecosystems peopple can forget that fungi decompose orgfanic waste
prevention
organisations around the globe have taken action to conserve biodiversity(MPA's)
(MPA's):area's in the sea that have special rules to preserve biodiversity
