Threats To Biodiversity
Poullution
pollution is harmful gases liquids and more .
When we drive cars,buses and more and when we spill teh oil in teh water we destroy many habitats and kill wild life with it.
For example,Fertilizers are washed away to bodies of water like the gulf of mexico causing rapid growth of undesirable types of algae
the consequences are pollution in air,water can hurt/kill plants and animals
Invasive species
When species are introduced to a habitat they are called non native species,some native species can threat environments and habitats and they are called invasive species
When humans bring plants or tom one ecosystem to another and this may happen accidentally or on purpose
For example,when the brown tree snake was introduced to its new environment it started to eat a lot of the other species
the consequences native species and introduced species fight for resources and change way environment works
Climate Change
its the change of earths weather
Human burning of fossil fues release large amounts of gases into the air which cause climate/weather change
For example, in the arctic the ice is melting
the consequences are species cannot adapt with rising temuptures
Habitat loss
When humans destroy a habitat to make houses.etc they reduce it to a little bit for the biodiversity
when habitats are cleared to farm,build cities,roads and more which makes less space for the biodiversity which sometime leads to killing biodiversity .
For example,The conversion of tropical forests to palm oil plantations is placing stress on population of orangutans,tigers,elephants,and rhinos
the consequences are habitat loss reduce species richness
Over-harvesting
Humans use too much of a resource and ends up destroying them
when humans use too much of a resource they destroy it which causes damage to habitats and environments
For example,mahogany is a type of tree which makes furniture and instruments so people chop them down but this type of tree grows slowly so there isnt enough mahogany for the resources .
the consequences are leads to loss of biodiversity and environmental consequences
