how does de - icing roads with salt negatively impact the environment?\na. the road salt attracts deer that are then hit by motor vehicles.\nb. it removes necessary salt from the local water courses.\nc. the high salinity of the surface runoff is harmful to freshwater ecosystems.\nd. the salt harbors salt eating bacteria that are toxic to animals.\nplease select the best answer from the choices provided\no a\no b\no c\no d
Answer
Brief Explanations:
When salt is used for de - icing roads, it dissolves in water and runs off into water bodies. The high salinity of this surface runoff can disrupt the osmotic balance in freshwater organisms and damage freshwater ecosystems. Option a is not the main environmental impact related to salt's ecological effects. Option b is incorrect as road salt adds salt to water courses rather than removing it. Option d is not a common environmental impact of road salt; there is no significant issue of salt - harboring toxic salt - eating bacteria.
Answer:
C. The high salinity of the surface runoff is harmful to freshwater ecosystems.
