Increased amounts of vegetation is NOT a long-term effect of mining in the Picher Mining District   (Option D)

Explanation: However, these mines as much as they contribute, they are destroying our environment and contribute in global warming.

There are many long-term effects of mining:  

- Due to mining, many of the resources may run out in the next ten years  

- Mines can cause erosion  

-causes Loss of bio-diversity  

- Pollution in the soil, water and air  

- Machines that are used in mining also produce large amount of greenhouse gases

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
