Aquatic organisms need to be conserved because their environment is very fragile. If water is polluted it could kill a lot of organism and could even cause the extinction of species. There are many different types of organisms that live in an aquatic environment. Of these organisms some may spend their whole lives in water, and other may only spend part of their life in water. But both are affected greatly by their aquatic environments. Aquatic organisms can be found in either fresh or salt water varying from rivers, streams, lakes, ponds, marines, and estuaries. Organisms can die or be mutated if their aquatic environment is polluted. Amphibians for an example are aquatic organisms living in rainforests or wetlands, and some in cities. The amphibian population has decreased, and some species have become extinct because of polluted water. There are many types of other aquatic organism that depend completely on their aquatic environment and right now are very threatened or endangered because of human carelessness destroying their environment with pollution. The fish we eat, mammals, amphibians, invertebrates, reptiles, and aquatic plants need to be in conservation because their delicate environment is being threatened, there are groups such as the IUNC (World Conservation Union) who are trying to conserve as many species as they can.

Scientists at UCLA were able to trigger special parts of the brain in a middle aged study group with little experience surfing the web. The scientists gave the study group, all between the ages of 55 and 78, functional magnetic resonance imaging scans to see what parts of their brains were working. During the first internet browsing session, the participants were using parts of their brain controlling language, reading, memory and visual abilities. After being sent home and web surfing an hour a day, the participants came back for another scan. The second scan showed activation of the same regions as the first scan, as well as triggering of the middle frontal gyrus and inferior frontal gyrus. These areas are important in the brain for working memory and decision making. The study shows that searching on the internet may be a simple form of brain exercise.
