How is population dynamics in animals affected by sewage water release <br> plzz helppp
Hitman42 [59]

Answer:

It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.

Explanation:

Research has shown that population size and growth are important factors in the emission of greenhouse gases. ... While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.

If sewage is only partially treated before it is disposed of, it can contaminate water and harm huge amounts of wildlife. Alternatively, leaking or flooding can cause completely untreated sewage to enter rivers and other water sources, causing them to become polluted. The consequences aren't great

Factors influencing population growth

+Economic development. ...

+Education. ...

+Quality of children. ...

+Welfare payments/State pensions. ...

+Social and cultural factors. ...

+Availability of family planning. ...

+Female labour market participation. ...

+Death rates – Level of medical provision.
