This may even lead to primary consumers to eat plastic. Also, research shows that fish cannot detect these dead zones so once they enter them they most likely will not get out. In addition to this, contaminated fish and marine life humans consume can contribute to diseases and problems within the human body. Exposition to chemicals such as chemicals in plastic bottles and pesticides can cause hormonal problems, reproductive problems, nervous system damage and kidney damage. Also according to Planet Aid “Bacteria turn metals into its most toxic form which is then absorbed
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health.
Describe four factors that influence ocean currents. o Wind: it is the single strongest factor in the creation of surface currents. Strong winds moving across an expanse of water move the surface of the water. The strong winds are not random breezes.
Overfishing Overfishing means to deplete or exhaust a stock of fish or shellfish by excessive fishing. This may not seem like a topic that is ever worth argueing over, or worth making laws for, but little do people know that the consequences of overfishing will soon affect the entire world. This will not only affect ocean life, it will also affect humans, as well as all other living organisms lives as well. There are already several overfishing laws existing, but they are easily avoidable and is done so with so many large fishing companies.
Constructive waves are long waves and roll on to the beach rather than crashing. Ultimately, constructive waves create wide, gently sloping beaches (Figure 2). The beach profile undergoes seasonal changes due to change in wave energy. In temperate areas, summer beach profiles are characterized by: calm seas, long periods between breaking wave crests, and increased deposition thus high beach profiles.
Tsunamis can require hundreds of thousands of lives and devastate entire communities within only a few minutes after the wave reaches land. Another reason that tsunamis are so dangerous is that they are not really going to do something to prevent the massive wave power and it is very fast for a tsunami to be formed and travels through the sea to the land. Because it is difficult to prevent tsunamis and for the reason that it goes very quickly, it is important to alert and to be prepared, especially the most affected areas, to make the consequences of the tsunami mitigated. Man has destroyed ecosystems such as coral reefs and sandbanks which has served as a shelter to slow tsunamis.
A benefit is that wind turbines are sustainable. Winds are made because of the heating in the atmosphere because of the sun and the rotation of the earth. As long as the sun is shining and the wind is blowing
On the other hand, the meiofauna found on beaches with large grain sizes can reach deep into the sediment (Rodriguez et al., 2003), in order to avoid the effects of wave action at the surface. Macrofauna can be negatively affected by wave action on beaches with high wave action and, therefore, tend to reside in more favourable beaches that have less wave action (McLachlan et al., 1996; Rodriguez et al.,
However, it still cannot avoid some issues such as the piracy and terrorist issues. Besides that, the increasing of the ships and other maritime related activity will bring the issue of the environmental pollution issue. It will bring the threats of maritime pollution because of the accidental spills, illegal dumping of waste, and so on. As well as, that will influence the health of the human and organism inside the sea. Therefore, to address maritime security concern requires international efforts.
From (-- removed HTML --) I found this very interesting as I thought the local tsunamis waves would move very fast towards the dry lands and I would’ve thought the distant tsunami waves would move faster because it is moving into the open ocean. This allowed the Samoan citizens to evacuate to higher grounds to become more safe form the tsunami that was about to happen as Samoa is a very mountainous
The Hobie Island Tandem The Hobie Island Adventure is one of the most popular choices for people who wanted a variety of boats to be combined into one. Upon its first release, people were fascinated by the fact that the single person kayak shaped boat could also perform as a paddle boat or a sail boat, depending on what they were up for on that boating adventure. The Hobie Island Tandem offers the same unique features, but it is doubled and allows you to go out with a partner. What is the Hobie Island Tandem?
Barrier beaches will only occur when there is enough sand for the beach to form, sea levels are rising, and there is sufficient energy from waves and wind to move the sand2. Since these beaches are made wholly of sand, they are constantly being moved by the waves and wind by which they were formed. Barrier beaches such as Monomoy promote the development of marsh and wetland habitats, by protecting the area from harsh wind and waves. Monomoy Island is an important aspect of the cape cod coast. Located at the southern tip of the outer cape, it provides a home for countless seals and other wild life.
This affects the climate of Juneau because water has a very high specific heat, which means that it takes a lot of energy to raise the temperature one degree. Due to being on the coast of a large body of water, the temperature of Juneau doesn’t vary much because the water near or surrounding the city takes longer to heat up and longer to cool down than land masses, so cities near water tend to have less
Plus it was affecting the wildlife as well mostly having an effect on the birds. The oil would stick to their feathers causing it hard to fl and get away from their predators plus the oil would get into their face causing problems for the bird. Than in the Pacific Ocean there is a belt all along the Pacific Ocean called the Great Pacific Garbage Patch. This is caused by currents pushing all the debris out to see from, rivers, streams, harbors, storm drains, etc. This pollution belt causes many problems for the ecosystems is comes across with.
A world class professional surfer named Rick “Frosty” Hesson, who has surfed the biggest waves on the planet once said, “If you're having a bad day, catch a wave.” Surfing can be stress relieving, fun, or even competitive. At times surfing can be very dangerous, from surf spots getting too crowded, polluted waters, or drowning. Human nature is underhanded. The tides are always changing, new sets are forming, and the undertow is contemporary.
