Firstly as we all known the melting of glacier not only bring negative impacts toward the earth but also jeopardizes human lives on earth. The negative impacts such as animal habitat losses, fresh water shortage, minimize the ability to generate the electric power, and excessive flooding incident.
No doubt that the melting of glacier will effect the amount of fresh water storage, this is because almost all the water available on earth is contain 70% of salt water, which is unsuitable for human usage, and only 2% make-up of earth glacier. The sources of fresh water are from the melting water from glacier which flow into the rivers or lakes, and the melted water gets renewed as ice on the glacier went through a process known as precipitation. In addition many part of the world relay on this source to obtained fresh water. Therefore, the melting of glacier mass will only cause shortage of fresh water supply.
Next is the shortage of electricity. Electricity is important for our daily uses, and the demand of electricity is increased day by day as the human population increased. In order to generate this power source it needs constant flow of water from the melting water of glacier. And when the melting water from glacier is reduced due to the melting of glacier, certainly it will stop the production of electricity. Absolutely no nation can do without electricity, and this leads to adopt different sources to produce electricity, where most of them will pollute the earth, and possibly even help increase global warming.
Finally, the flooding incident occurred as a result of meting of glacier. Places with ice glacier on higher altitude and melting rapidly will bring the sudden increase of water input to the water causing flood all over the places. And this exceeds amount of water form a new lake where it size keep increasing and the bursting of such lakes could cause a major catastrophe all around, destroying everything in its path.
