Water pollution is a very prevalent problem throughout the world. It affects ecosystems, deters the natural food chain, and can cause disease in both animals and humans. But is water pollution affecting natural lakes and ponds in local areas? In this experiment, Daphnia magna will be used in a bioassay to find if water from local areas is habitable for aquatic organisms. Daphnia magna are small freshwater invertebrate organisms.
This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem. Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold.
The quality of the water you fish also makes the difference in your bass fishing tactics. In muddy water, for example, the bass uses their sonar to locate food. So choose lures that vibrate well and maybe make noise. In clear water, however, the basses are very cautious and suspicious of something unusual. So you need bright lines and lures that look a lot like local food sources.
Therefore the fish die. Not only does fishing equipment cause these deaths, but so does trash. I live in Ghana which happens to be on the Atlantic ocean. The people here dump their trash in the Atlantic ocean. So many of time what happens is fish get all caught up in the peoples mess, and they die as a
Luther King says in "9 Interesting Facts and Statistics about Littering", 1.9 billion tons of litter end up in the ocean. The ocean is another ecosystem made up of many diverse animals and plants. In “ 5 Ways Pollution Is Killing Animals”, Abigail Geer tells us that there are many things that can pollute the water ranging from noise, chemical and acid runoff, waste water and oils. All of these types of pollutions are affecting the marine life drastically. Abigail tells us that noise pollution is hurting animals that use sonar to get around are becoming closer to extinction.
Lake Michigan is home to very diverse populations and species. The introduction of Asian carp into the Great Lakes has had an adverse effect on native fish and could jeopardize the fishing industry, particularly lake perch and trout populations. The Asian carp eat many tiny plants and animals, which are food for many native fish. This will eventually affect the population and growth of the Great Lakes native fish. The Asian carp should be removed from the Great Lakes as shown in the following paragraphs.
mainly talked about the Illegal, Unreported and Unregulated (IUU) fishing both in US domestic waters as well as high seas. IUU fishing impacts sustainable global fisheries, food security, marine ecosystems, and conservation and management measures that protect marine resources. According to NOAA, IUU fishing significantly affects multi-billion dollar US fisheries industry. Therefore, I think the speaker is addressing an important issue. I learned a bunch of new things from this presentation.
The sharks have a major role in the ocean and people do not know that's why we have to save sharks. Plus they have many predators that can kill them in the ocean. One of the threats is humans, the reason is that countries are fishing them. They fish sharks and they take off their fins for an Asian food that's supposed to be a delicacy. There are high demands for shark fins and it's really
Agriculture immensely adds to the nutrient and chemical pollution due to the fertilizers used on crops. When rains or winds come through the fertilizer is carried from the fields into the rivers and streams that then lead into the ocean(Effect of Runoff). Red tide had been a huge issue that is unpreventable and caused by dinoflagellates (Red Tide). Red Tide is a type of algal bloom that takes up oxygen in the water. When the oxygen levels in the ocean are lowered it can kill many plants which is very unfortunate for the manatees considering they are herbivores and with their food supply being depleted they may suffer from starvation.
