Geography: THE DOWNSIDE OF MINING

Original post by @eghe21

Mining has obviously improved the economic growth and development of Nations and even individuals,but it also has the negative effects on man and his environment.

Perhaps,the most significant impact of a mining project is it effects on water quality and it's availability within the project area.

When mined materials are excavated and exposed to oxygen and water,acid can form if iron sulfide minerals are abundant and there is an insufficient amount of neutralizing material to counter the formation of acid.

The acid will dissolve metals and other contaminants and form an acidic solution. If uncontrolled,the acid mine drainage may runoff into streams or rivers or into groundwater. Plants,animals are unlikely to survive in these conditions.

This was todays selection of post. Make sure to check out other authors and upvote this post to support the project!

Transparency

The project tries to be as transparent as possible. For any questions you can reach out to the discord channel.

The initiative and actual selection of posts is done by me, @samve. For sake of convenience I will never upvote my own posts, but since I put effort in writing as well, please give my blog a look and follow me if you would like what you see 😉.

Upvoting and resteeming posts of Geopolis allows us to grow which will results in larger upvotes flowing back to the people creating quality posts = you. All rewards from posts by Geopolis will be used by the community to grow.
