Pollution and exploitation of Marine ecosystem: 2
Answer a
Pollution is contamination of natural environment that causes adverse effect on the
environment and biodiversity. Majorly, the classified types of pollution are water pollution,
air pollution, noise pollution, soil pollution, and marine pollution. Marine pollution ruins the
marine mammals such as fishes, sea lions, and dolphins. The ethics are the moral principles
that motivate a person to conduct an activity. Today`s ethical issue of marine pollution is lack
of environmental responsibility. The discharge from industries, pesticides, and fertiliser from
agriculture, the sewage system of municipals are diverting their waste to oceans and seas.
Oceans cover almost 70% of the total surface on earth. Reportedly, ocean covers around 70%
of the planet are with the marine ecosystem as compared to terrestrial (Tupper, Asif, Garces,
& Pido, 2015, 33). In the phase of environmental change, there is a huge loss of marine life
species and the remaining species have weaken the ability to reproduce. The major threat to
marine life is exploitation and destruction of coastal habitats. A large number of sea creatures
depend on the seashore for the process of breeding. The marine species suffer from use of
plastic bags to a major extent.
Answer b
Due to contamination of seawater, the people who use seawater to perform their
routine activities affect their health. Unsafe drinking water is one of the major cause of child
mortality. Reportedly, over 1.9 million kids lose their life due to unsafe drinking water. The
prevention step can be either stopping the contamination of drinking water or finding new
ways to clean the water before drinking. Plastic is the major fabricated debris in the ocean.
Reportedly, 839 marine plastics are the small fragments of large materials made up of
polyethene and polypropylene such as packaging and fishing objects. Meanwhile, the
concentration of plastic is 4256.6 pieces km-2 and it has been increasing after adding the
