The Earth's Water Cycle involves Evaporation, Condensation, and Precipitation. Evaporation purifies the water resulting to the replenishment of freshwater to the Earth.
Water pollution is a concern despite of the water being continuously cycled through Earth's systems because the source of pollution is has not been removed.
Water pollution is defined as the contamination of bodies of water. Pollutants are directly or indirectly released to the bodies of water causing the water to be polluted.
Imagine: A river is filled with garbage, it is polluted. The water from the river undergoes the water cycle but since the garbage is still present in the river, the freshwater that comes from precipitation becomes polluted.
The bloom in the population of algae might negatively affect the ecosystem because big changes to the population of one organism in an ecosystem could affect other organisms.
<h3>Effects of population change</h3>
A sudden increase in the population of a species in an ecosystem could affect the population of other species in ways we could not even imagine.
The population expansion could create several problems such as competition for space, nutrients, and even food. Another problem could be pollution.

The reason for that is the song gets imprinted on the young birds. Have in mind that birds rised alone will sing but the local pattern will not influence the singing of that bird.

Still have in mind that young birds that are alone can also sing but in a different way, not the one proposed by the environment.
