Actually Welcome to the Concept of the Genes.
Basically a Polygenetic trait is controlled by two or more genes.
Examples of human polygenic inheritance are height, skin color, eye color and weight. Polygenes exist in other organisms, as well.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Also Humans may destroy natural landscapes as they mine resources and urbanize areas. This is detrimental, as it displaces residing species, reducing available habitats and food sources. ... This can negatively effect an ecosystem because the introduced species may outcompete native organisms and displace them.

Answer:
Salt lowers the freezing point of water via freezing point depression. ... When salted ice melts, the water can't refreeze as readily because the saline isn't pure water anymore and because the freezing point is colder. As more ice melts, more heat is absorbed, bringing the temperature down even lower.
