DDT and other pesticides used over 50 years ago are still affecting the environment today. Scientists have found these substances in recent glacier runoff. Glacier runoff occurs during the summer, when precipitation that has fallen on glaciers during the winter is released. Ice layers from existing glaciers have been analyzed. The results of this analysis show that the concentrations of DDT and other pesticides were highest about 10 years after the use of these substances was banned. This information shows that

• DDT and other pesticides cause glacier runoff during the summer.
• it takes humans over 50 years to analyze a glacier.
• precipitation helps to break down pesticides.
• the decision of one human generation may have an impact on future generations.

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 change.
