For example, rather than giving control to the fisheries in determining how they use the land, regulations should determine what practice can be used to protect the ecosystems around aquaculture facilities. The facilities should also not cause destruction of any key habitats, such as the mangrove swamps that commonly get destroyed. Aquaculture also results in increased pollution, which sometimes threatens the native wish in the area. To encourage cleaner fish farm production, the government could provide subsidies to companies that pollute less while fining those with high levels of pollution. These types of policies and regulation in conjunction with the Endangered Species Act would promote population stability or group in threatened fish
Oceans are vast water bodies, and large quantities of wastes have been dumped into them under the assumption that its not a serious problem. But recently many reports show that ocean waste is accumulating at remote sea shores causing problems to the local people there. This has brought into light that dumping waste in oceans is not sustainable. Earlier, the wetlands used to help filter out a major share of the pollutants from the runoff before it joins the surface water. As cities expanded, most of the wetlands got converted for construction
This will result in more infrastructures and waterways that were supposed to be natural are now used to drain off the run off water. In urban areas that are highly-urbanized, the rain becomes surface runoff. This run off from these urbanized areas can cause channel erosion, habitat damage to the animals, and clogged stream channels. These changes in the water cycle have great effects on the atmosphere. For example, clean water will be harder to find for fish, humans, and other wildlife.
Poldering is the provision of a ring bund surrounding the area to be protected. This is normally carried out for an area which has high damage potential but for which the cost on overall basin-wide protection would be prohibitive. It includes the provision of internal drainage for the area to be protected and the evacuation of flood water by pumping during periods of high river flows. Canalization also suitable in overcome flash flood. Canalization works include the widening and deepening of channels as well as lining the banks and beds of the channels.
The use of chemical control also poses a challenge especially when it is to be applied on a shared resource e.g. Lake Victoria. This then warrants a joint agreement from all countries that directly or indirectly depend on the resource. 2, 4-D and Glyphosate are examples of herbicides that can be used as they can kill the weeds fast. It should however be noted that the huge mass of dead plant material can lead
Due to the saltwater transition, and the filth within the water, the water was the reason for many diseases. These were diseases that the English were not used to. For the English to be infected, it must have been awful with the lack of resources the English collected. “The Lost Colony and Jamestown Droughts,” represents the amount of rain received every year based on the average amount of rainfall. It also shows the droughts that happened in those few years.
These were mainly of two kinds: the tsunami of open-ocean sea wave, generated by large-scale motion of the sea floor; and the local wave, generated by underwater landslides in bays of fiords. The 1964 Alaska tsunami was the second largest ever recorded, again following only the one caused by the 1960 Chile earthquake (4 meters at Sitka). Of the 119 deaths attributable to the effects of the ocean, about one-third were due to the open-ocean tsunami: 4 at Newport Beach, Oregon; 12 at Crescent City, California; and about 21 in Alaska. Local waves claimed at least 82 lives. Maximum height reported for these waves were 70 meters in Valdez Arm.
Many shoreline businesses got ruined and many seafood businesses had to be temporally shut down due to loss of sea life around the coast of Samoa. After the tsunami hit Samoa, as well as Tonga, it receded back into the Pacific Ocean, taking a great amount of rubbish along. This polluted the ocean a lot, it was responsible for many deaths of various sea animals. As well as land
The Great Pacific Garbage Patch is a gyre in the Pacific Ocean which has been collecting marine debris for many years, forming a trash vortex of astounding size in the middle of the ocean. The majority of the trash collected is plastic, or microplastics, due to their extremely resistant nature based on their chemical composition. They are bonded so tightly that it is incredibly difficult to break the plastics down, so instead, they remain in the Great Pacific Garbage Patch for indefinite periods of time, damaging aquatic life and polluting the waters. The Great Pacific Garbage Patch has been portrayed to the public as a growing, urgent issue, which can be solved if we work together to remedy the problem. This general presentation is fair to the problem, as the trash vortex does pose a great threat to aquatic life, and its pollution of the sea is far from desirable.
