Explain why nonpoint source pollution is a greater threat and hazard than point source pollution.

Pollution by non-point sources is more dangerous than pollution caused by non-point sources because they are unknown and identifiable sources that cannot be controlled or ended.

Explanation:

Pollutants are introduced into the environment through sources. These sources can be classified as punctual or non-punctual.

Point sources are so called because they do not have a specific launching point or because they do not come from a precise point of generation. These sources are identifiable and are generally impossible to track, thus making it difficult to control and identify. Examples of non-point sources: the infiltration of pesticides in the soil from agricultural fields, the supply of nutrients in streams and rivers through urban drainage.

and 3 true im assuming these are true or false. hope this

this disease is :

* endemic (present in a defined area that is a village)

* a bacterial infection (treated with antibiotic)

* communicable by contact (by the hands)

manu-porterage is the most common mode of transmission, it transmits germs from one individual to another via the hands. this concerns infections of exogenous origin.

endemic disease, or endemic disease, refers to a disease that is constantly present in a given population, often tied to a specific geographic origin, as opposed to a pandemic that is not a sporadic disease.

antibiotics are molecules that have the property of killing (bactericidal) or limiting the spread (bacteriostatic) of bacteria.
