FIVE FACTS FROM THE SOURCE (Embedded):

The article brings to attention the fact that "It is important to know how a simple act like introducing sewage water or toxic waste into a lake can threaten several life species and plants in the area" which is important because many people believe small things won't have any impact, when actually they do.

The article reveals important contributing factors by stating "Pollutants like oil, detergents, nitrogen and phosphate from fertilizers and lead can have a tremendous impact on the ecosystem, especially if the water gets polluted" bringing up the fact that polluted water is one of the worst effects pollution has on ecosystems.

The article goes on to provide an example by saying, "In a lake, for example, it [pollution] can wreak havoc on the ecological balance by stimulating plant growth and causing the death of fish due to suffocation resulting from lack of oxygen" providing a real life situation that pollution could potentially cause anywhere.

The article continues by saying "The oxygen cycle will stop, and the polluted water will also affect the animals dependant on the lake water," bringing up the seriousness of the effects of the pollution, as it affects all the animals dependent in the ecosystem such as a lake.
