The Amazon rainforest in South America has large quantities of copper, tin, nickel, bauxite, manganese, iron ore and gold, making it attractive to mining companies all around the world.
How does mining affect the forest?
The indirect impacts of infrastructure development for large-scale mines, particularly in previously unexplored forest areas, pose a significant threat to forests: the construction of transport infrastructure may open up remote forests to other activities, such as logging, hunting and agriculture.
Is there gold in the Amazon River?

Why is mining bad for the environment?
Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local ...
How dangerous is mining?
Mines are often home to many dangerous gases including carbon monoxide, hydrogen sulfide, methane, and carbon dioxide. Due to the confined spaces, these gases are not always able to escape, building up within the mine. And due to their combustible, explosive, or toxic qualities, this is a very serious issue.
What type of mining is most harmful to the environment?
Although the effects of coal mining take a long time to impact the environment the burning of coals and fires which can burn up to decades can release flying ash and increase the greenhouse gasses. Specifically strip mining that can destroy landscapes, forests, and wildlife habitats that are near the sites.

Health impacts due to inhalation of PM emission from surface mines—medical evidence. PM exposure to surface mining workers lead to some common diseases such as asthma, black lungs, silicosis, asbestosis, inflammation, bauxite fibrosis and siderosis (Singh et al., 2009).
What are two kinds of pollution caused by mining?

Does mining use a lot of water?
Mining uses water primarily for mineral processing, dust suppression, slurry transport and employees' needs. ... In many cases, especially with underground mining, water needs to be pumped away from a mine site, which can reduce the levels of ground water, deplete surface water or cause pollution to local rivers.
How does copper mining affect the environment?
The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people's skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage nearby buildings. The acid dust both smells and tastes bad.
How open pit mining affects the environment?
Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular.
