5.3 mindmap
Biodiversity and why we should protect it
species proide vital ecosystem services that keeps us alive
Insects polinate, tress produce oxygen, earthworms recylce nutrients etc
economic services
Food crops, wood for fuel and construction, medicine
Ecotourism
These species also have the right to live
How are we damaging the Ecosystem? :
HIPPCO
Habitat Destruction and degradation
Destruction of forests for cattle or crops
Wetlands for residential developments
Degradation due to pollution caused by human activities
Invasive species
Non native
Introduced for benefit
No natural predators so they take over niches and dirupt ecosystems
How to control them?
Biological control: fight invasive species with invasive species
Mechanical Control: manually remove them from ecosystem
Chemical control: herbicides and pesticdes
Some introduced by accident
Can even spread new diseases
Population growth
Inefficient use of our resources and a growing population causes depletion of resources
Over explotation
legal but unsustainable use of wild organisms
Poaching
Exotic pets
Bushmeat
Traditional medicine
Persecution
Decoration
forestry
fishing
Climate Change
Temperatures rise too fast for animals to adapt
Habitat loss
loss of species
Pollution
Chemicals that damage the atmosphere and the everything around them
Can make some animals infertile
Contamation of water bodies
Burning of fossil fuels causing global warming
