This becomes the breeding ground for water-borne diseases causing insects and organisms like mosquitoes to flourish.

Loss of Biodiversity 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 that dwell in the forests.

Examples of the Environmental Impact of Mining Rainforests are the biggest source of oxygen, wood and medicines on this earth. Amazon rainforest is known for its alluvial gold deposits.


Gold is found both in river channels and at the banks of the river after floods floodplains. Hydraulic mining techniques are used for mining gold. The method involves blasting at the banks of the river. This has caused irreversible damage to trees, birds and animals.

While separating the sediment and mercury from the gold-yielding gravel deposits, small-scale miners who are less equipped than industrial miners, may ignore release of some mercury into the river. This mercury enters the food chain through aquatic animals and their predators. Highly poisonous compound ‘cyanide’ is also used to separate gold from sediment and rock. In spite of all precautionary measures, it sometimes escapes into the surrounding environment.

Those who eat fish are at greater risk of ingesting such toxins. Inin Guyana, more than four billion liters of waste water that contained cyanide, slipped into a tributary of the Essequibo; when the tailings dam, which was filled with cyanide waste, collapsed.

How Are We Destroying the Environment?

All the fish in the river died, plant and animal life was completely destroyed, and floodplain soils were heavily poisoned, making the land useless for agriculture. The main source of drinking water for the local people was also polluted.
