Overpopulation, Invasive Species, and Overfishing are just three large environmental problems we face today.
Overpopulation is happening in a lot of species on Earth today, including humans, and can be a problem for all levels of civilization from the whole biosphere to a small community. Overpopulation is when the population becomes too large for what the environment’s resources allows. Overpopulation is a major issue to humans because we don’t know what the carrying capacity is yet, and how it will affect us. With 7 billion people on this Earth the capacity is approaching quickly. Humans already face many problems because of our population size, with a shortage of water and food. A good example of how we are being affected right now is on this site here. ” Each day 40,000 children die from malnutrition and its related diseases. we do not address this problem, we may begin to see a battle for survival against ourselves.” Addressing the problem is a big struggle, and may not become apparent to people until the carrying capacity is reached. One major difference between the human race carrying capacity and a different organism’s is that with advances in medicine we have worked around problems that normally contribute to slowing growth.
Will there ever be a point where the advances in technology aren’t fast enough to counter the many struggles us humans face?
Invasive species offer another large environmental problem. Invasive species are organisms that are foreign to an area. These organisms disrupt the environment and can set the ecosystem off balance by using resources, or destroying food chains. Anexample in our area of an invasive species is the Zebra mussel. The Zebra mussel (Above) was passed by the transition of boats between water bodies. A solution to stopping the spread of Zebra mussel is to stop the spreading at its source by washing
boat hulls (Left), which is one thing the Minnesota DNR is trying to do. It is often human activity that causes species to move from their area, so before we take part in something that might disrupt nature, research is key. An organization that is already taking their part to stop invasive species is the Nature Conservancywith a 6-step plan that goes beyond one problem. If problems are not addressed environments can be destroyed by an overwhelming species. It is difficult to realize how invasive species can happen, so education is vital to encourage people to think about how they may be affecting an environment by proceeding with an activity as simple as fishing.
Since human interaction in nature cannot be eliminated without removing humans, how can we balance out the impact of the interactions we have on the environment?environment by proceeding with an activity as simple as fishing.
Overfishing is another environmental problem caused by humans. Overfishing is caused by the ever-expanding fishing industry. Overfishing can cause ecosystem imbalances much like invasive species, but overfishing can be monitored much easier. In our area, overfishing is big problem because of the many lakes that surround us. Action is already established to control fishing, but not all water bodies can be supervised. Not all people think about how they are affecting the environment so education on the subject is a key solution, making people acquire their fishing licenses after a test would slow down overfishing. A site that is already creating materials for educating the public is located here. There are other solutions, like fish farming but in small lakes this method isn’t very practical.
How could we make fish farming practical to all of the world?
