Crayfish need calcium in order to maintain a healthy exoskeleton. However, when a lake’s pH decreases, most of the minerals diminish as well. Affecting the crayfish in the process as they are weak and their source of food is being limited as well. Crayfish can be found in Australia and many other parts of the world but most commonly in North America, specially U.S.A. Due to the EPA foundation, they are not extinct. EPA has used liming in many lakes in order to save many aquatic animals. If EPA didn’t exist, many aquatic animals would be classified as extinct, as they cannot survive in a toxic environment. In 30 years, we believe crayfish are not going to be classified as extinct, as there are many programs trying to solve the problem, and some of their solutions have already worked. For instance, the lake in New England. It’s pH level is neutralizing due to liming and many other chemical solutions. If all lakes respond as well to all the chemically different aspects, there won’t be any extinct crayfish. Clams are also being affected. Clams can’t live in a lake in which it’s pH level is less than 5, as they need different nutrients the water can’t provide at this point and …show more content…
It has been proven over time that mayfly are affected by the acidification of water. For example, lake Erie. This lake provides many myfly to the environment but when acid rain starts to affect the water, the population of myfly decreases. When this lake went through liming, the number of myfly increased. However, when acid rain struck again, the myfly would die and would only make a comeback after a second liming of water. Myfly won’t be extinct in 30 years, because when they are in the verge of becoming, the government or other organizations will start the process of liming in order to increase the population
