- degree of variation of life forms within a given species, ecosystem, biome, or an entire planet.
- it is the variety of a species or life forms within an area.
There are different ways of decreasing the biodiversity within an area. One threat is over exploitation. Exploitation occurs when a resource is consumed at an unsustainable rate. Forms like overhunting, excessive logging, poor soil conservation and illegal wildlife trade. I believe that Mining is another form of decreasing the biodiversity.
Lutopan use to be filled with a variety of forests. But mining destroyed all of this. The forests that are cleared for mining purposes are home to a large number of organisms. Indiscriminate clearing of the forests leads to loss of habitat of a large number of animals. This puts the survival of a large number of animal species at stake. The cutting down of trees in itself is a big threat to a number of plants, trees, birds and animals growing in the forests.he forests that are cleared for mining purposes are home to a large number of organisms.

Other known impacts of mining on biodiversity:
- Water quality can be negatively impacted by heavy metals and acid minedrainage, causing significant damage to ecosystems; poisoning fish and mammals through bio-accumulation.
- Water quantity can be reduced caused by draw-down of groundwater orstreamflow reduction for operational mining and use in processing facilities.
- Land change from mining activities causes profound disturbance to the landscape. Excavations for extraction, waste rock and tailings ponds all modify the shape and hydrology of the landscape.
