Salt water is an abundant resource but unusable for irrigation and drinking. As demands on freshwater sources increase, the use of desalination processes to remove salt from ocean water is increasing. A concern of desalinating water is the large amounts of recovered salts that are returned to the ocean. Which of the following describes the most likely impact of desalination on the surrounding ocean environment?
Alteration of habitat
methane pollution from dead organisms
depleting of nonrenewable resources
overpopulation of bivalves
The northern elephant seal was almost hunted to extinction in the 1800s. By the late 1890s, approximately one hundred seals were left, reducing the gene pool of the population. What will be the consequence of this reduction?
competition within the population will increase
the surviving elephant seals will be better able to adapt
Inbreeding will be less frequent among the remaining population
the elephant seals will be more vulnerable to environmental changes
