Illustrate the hazards to the aquatic environment (oceans, lakes, and rivers) associatedwith
environmental pollution
These nutrients are washed away from land and farms heavily riddled with fertilizers that are
nitrogenous and phosphatic. By washing these leachable nutrients from the soil into water bodies
such as rivers and streams, which ultimately end up in large reservoirs such as lakes and oceans,
rain acts as an agent for that occurrence. Via irrigation systems, these nutrients are often released
into waterways (Heath, 2018). Untreated wastewater makes its way into water bodies due to
inadequate sewage treatment. It causes algal bloom through the eutrophication process because it
is high in nitrogen compounds such as nitrates and ammonia. Water pollution, especially the
discharge into waterways of poorly handled or untreated industrial waste, contributes to the release
of raw toxic waste. The effect is the dense growth of algae since it includes nutrients and
compounds such as nitrogen, lead, and phosphorus.
The ocean, lakes, and rivers hazards associated with environmental population happen when there
is the rapid development of toxic producing algae in water which causes harmful algae bloom
(Khatun, 2017). The nutrients runoff that causes detrimental algae is washed away from the farms
and heavily riddled with nitrogenous and phosphatic fertilizers. These leachable nutrients are
washed into water bodies from the soil, and they end up in large reservoirs such as oceans and
lakes with the help of rain which acts as a transportation agent. The irrigation systems also
contribute to releasing these harmful nutrients in waterways. Besides, inadequate sewage treatment
also causes algae bloom by making untreated wastewater into water bodies (Heath, 2018). This
process of untreated sewage getting into the water bodies is called eutrophication since such waste
contains many nitrogen compounds such as ammonia and nitrates. In addition, water pollution
contributes to the release of toxic waste into waterways by facilitating the discharge of untreated
industrial waste into the ocean or lakes.
What steps can individuals take to prevent water pollution?
Water pollution can be prevented in different ways, such as using fewer plastics, cleaning
chemicals, and reusing items. Cleaning of chemicals is essential since they are hazardous when
they enter into the supplies of water. Individuals should be advised to empty containers of

household cleaning supplies in the trash and not in the sink to avoid polluting water bodies
(Khatun, 2017). Further, people are also advised to use fewer plastics to prevent water pollution
since breaking down plastics after they are produced difficult. This has made most of the plastics
used by human beings be disposed of into water bodies supplies where it is not easy to fish out and
remove them. Lastly, individuals need to reuse items that cannot be recycled like plastics to avoid
dumping them into water bodies.
