living organisms
biotic
nonliving organisms
abiotic
Major contributing factor is the inhibition of human beings and the use of land for economic gains
Habitat loss and destruction
Alterations and sudden changes, either within species groups or within the environment, could begin to change entire ecosystems. Alterations in ecosystems are a critical factor contributing to species and habitat loss
Alterations in ecosystem composition
Over-hunting, overfishing, or over-collecting of species can quickly lead to its decline. Changing consumption patterns of humans is often cited as the key reason for this unsustainable exploitation of natural resources
Over-exploitation
Biological systems respond slowly to changes in their surrounding environment. Pollution and contamination cause irreversible damage to species and varieties
Pollution and contamination
Both climate variability and climate change cause biodiversity loss. Species and populations may be lost permanently if they are not provided with enough time to adapt to changing climatic conditions
Global climate change
