Question

A.Contamination of groundwater
B.Air pollution
C. Increased use of land for landfill
D.None of the above

Answer 1

Hint: Water pollution is one of the major types of pollution that is happening in the world. As the majority of the land mass is made by water, it is easier to get polluted and the consequence of water pollution will be high in volume given the fact that all the organisms on this planet are connected to the water system directly or indirectly. The key sources of water contamination are domestic and industrial waste that are dumped in water bodies and pollution from water reservoirs.

Complete answer:
As the world is exposed to fast growing developmental aspects within multiple fields using modern solutions, the outcomes of that will be impressive. But every positive factor comes with a negative underlying problem that will grow out of control. Pollution is one of these factors which took over the world at an accelerating rate that affected millions of people and the environment itself.
Pollution is the slow or immediate spread of pollutants and contaminants into the environment that can be dangerous or bring discomfort to humans or other living organisms, or that damage the environment. The pollutants can appear in the form of chemical substances, or energy. Pollutants occur naturally or they are man-made.
Pollutants can affect all the important resources. One of the main resources that is accessed by multiple organisms on this planet is the groundwater. It is one of the major sources covering more than quarter of the surface area of the Earth, used for irrigation and drinking. By contaminating the groundwater by hazardous wastes can cause serious environmental effects as well as health issues.it can also destroy the organisms that are living in the water.

Hence, the correct answer is option (A).

Note:There are multiple sources from which the water system can get polluted and can cause discomfort. Contamination from septic tank waste can cause illnesses such as hepatitis and dysentery. Toxins that have leached into well water sources may be caused by poisoning. Contaminated groundwater can also affect wildlife. Exposure to contaminated water can also result in other long-term consequences, such as some forms of cancer.
