Environmental effects

Environmental effect is the beneficial or adverse impact of human products, services, or activities on the environment. For example, the release of volatile organic compounds negatively affects the environment and causes smog formation. On the other hand, collecting litter and putting it in bins positively affects the environment.

When blue crabs living in full-strength seawater swell duringmolting, they take on the H2O that bloats their bodies from theseawater in which they live. They obtain some of the H2O bydrinking. In addition, data show that the activity of Na+–K+-ATPase in their gills increases as they start to swell duringmolting. This rise in ATPase activity suggests that the gillsincrease active transport of ions from the surrounding seawaterinto the blood of the crabs. How could this process help accountfor uptake of H2O?
