Global and Local Threats to Biodiversity

Global

Climate change - sea level rises, migration of species, habitat loss, increase in tropical storms

Habit destruction - linked with pop growth and economic development. Deforestation, land needed for cultivation (25%), increased soil erosion and flooding

Pollution - mainly human activity, acid rain caused by fossil fuel burning damaging lakes and forest

Desertification - 10-20% of drylands already degraded, caused by climate change, over grazing and poor farming

Over-exploitation - using recourses faster than being…
