Question One
In my opinion, the article helped me to acquire knowledge on environmental science and get to know dangers in the environment and their cautions. Also, it helped in broadening the career choices in the field of environmental sciences giving best chances on career paths.
Question Two
Most of the earth's abundant water isn’t usable for agriculture and human consumption because of its heavy load of sea salt. Ever since chemists began to manufacture substances that nature never invented, problems of water purifications have become complex, increasing dangers to water users. Samples of drinking water from an orchard tested showed that it contains enough chemicals that are harmful to your health.

Question Three
Some earth's organisms which are highly affected by polluted water sources. Chemicals used for control of insects, rodents, and unwanted vegetation may be applied deliberately into water sources which may destroy organisms such as plants and animals that live under water such as fish.
Question Four
There are ways in which water bodies are connected to each other. It is not possible to add pesticides to water anywhere without threatening its purity. Rain falls on the land and thus, settling down through pores and cracks in the soil penetrating deeper until it reaches the zone where all the pores are filled with water which is always on the move except what enters streams directly as rain or surface runoff. All running water was one-time ground water hence frightening as pollution of groundwater pollutes water everywhere.
Question Five
Chemical pollutants can be transferred from one place to another through a chain. Underground water contains chemicals from rainwater that penetrated through the soil and may cause the growth of planktons eaten by herbivores which are later eaten by carnivores. This poisonous sequence may rest on minute plants which are consumed by human beings.
