Sinkholes one major environmental risk of underground mining because, Underground mines may collapse after mining is complete, which causes sinkholes.
<u>Explanation:</u>
The movement that occurs on the surface of the ground is known as mine subsidence. This is mainly caused due to the collapse that happens in the cola or any clay mining works that occurs in the underground surface. When anything is extracted form the underground surface, some holes are made in the underground surface which are sinkholes.
The damages that are caused as a result of this can be claimed by Mine Subsidence Insurance Policy. This type of underground mining is very dangerous as it give rise to the formation of sinkholes. This is forms when there is collapsing of the surfaces in the underground occurs after the completion of the mining work.

However, tissue culture is derived from already differentiated cells. Therefore these cells are already determined and can only produce cell type of that plant from which they were derived.
