Persuasive Speech On Marine Otters

All of the lush national parks and historical engravings, like the Grand Canyon, won’t be safe if they’re put in the hands of the wrong people.

My formula would be $150(((1+.0042) ^360) -1)/.0042) = $107653.67 is the total future value. To get the interest it would be $107653.67 -36000=$71653.67

The overpopulation of Pollock is creating an environment with no sustainable food source for the sea lions. Commercial fishing would also provide an opportunity to fish in a way that is co-beneficial to the environment, rather than carelessly overfishing. In order for this plan to be successful, close numbers of Pollock, herring, and Western stock sea lions will have to be observed and recorded. If immediate action is taken, the sea lion population could rebound within a few generations.

AP Environmental Science: Chapter 5 1. Explain how southern sea otters act as a keystone species in kelp beds. The otters help to keep sea urchins and other kelp-eating species from depleting highly productive and rapidly growing kelp forests, which provide habitats for a number of species in offshore coastal waters. Without southern sea otters, sea urchins would probably destroy the kelp forests and much of the rich biodiversity associated with them.

The author states that the pollution hypothesis seemed the most likely cause of otters decline along the Alaskan coast and provides three reasons. In contrast, the professor states that the ongiong investigation show that the predation theory is mst likely the cause of the decline and sh.e opposes each of the author 's reasons First, the reading claims that there were known sources of pollution along the Alaskan coast. However, the professor refutes this pint by saying that the pollution theory is weakened by that no dead sea otters were washed up to the shore. She said thet if the infection is the cause of the decline, there should be a lot of killed otters washed up, so this fact is consistent with the predation theory because if the sear otters were killedby predetors, they would not wash up to the shore.

Luckily, there are potential solutions and ways to control and remove this destructive intruder. Even though physical removal of the fish using nets, traps, angling, electrofishing or biological control by introduction of predators are not likely to be successful for large infestations, they can help control small amounts at a time. In addition to the threat of their predatory behavior and its resulting impacts, there is also a large concern about snakeheads ' transference of pathogens to native fish. Snakeheads carry a disease known as Epizootic Ulcerative Syndrome which can be carried and transferred to the native fish, deteriorating their population. At first, when a fish gets Epizootic Ulcerative Syndrome they will develop red spots on the skin.

Hello, everyone. Today, I’d like to introduce to you the decreasing of blue whales and think together from moral standpoint about some words which are carelessly used now and then. I’m afraid this topic a little deviates from environmental problems, but to prevent us from repeating same mistakes in nature, it is necessary not only survey natural environment but also overturn our thought against nature and all living things in the earth from the root. It has passed long time since the decreasing of the number of blue whale started to become the problem. We can attribute this problem to over whaling for the commercial purpose.

Their overly aggressive and territorial nature accounts for this. Pairs establish territories and defend them from other mute swans, birds, and mammals. Mute swans often cause the relocation of native birds from nesting and feeding areas. For example, they are responsible for driving the last remaining colony of black skimmers, a state-threatened species, from the Maryland portion of the Chesapeake Bay (Mute Swan…2003). Driving out a species is of less impact than high intensity interactions that can injure or even kill the “intruders”.

I can see it through the thing that the main character who can be an environmental protection or a biologist said about the Endangered Species Act also the place where she is working. They are trying to protect the salmon and it is the right thing to do with the endangered species. “Protecting an endangered species means changing the practices in an entire ecosystem to safeguard their survival. It means managing the loss of their habitat, the turbidity of their waters, the surface water runoff from the streets that threatens them, and the effluents from the wastewater that disrupt their endocrine systems and, if unchecked, will cause their extinction.” (Keith, 1) When you change any ecosystem of any species will be at high risk when that species do not adapt to the new environment, but with the management and gradual change, we really can save the species is nearing extinction.

People like Yao Ming need to lead the charge in shark conservation. As shark populations continue to plumment, the leaders is shark conservation in the world need to educate our world on the dangers we face if we continue to destroy the shark

In conclusion, the Zebra mussel is a growing nuisance for Canada’s waterways and overall ecosystem. In many ways it is obvious that Zebra mussels compromise the ecological integrity of the aquatic environments in Canada. Whether this be through the process of obstructing water flow, destroying landscape, or disruption of the food chain, the population of these invaders are growing increasingly worse. If the awareness of this invasive species and inspection for them is not in increased within our country, we will be faces with irreversible ecological damage in the

The reading states that the pollution hypothesis seemed the more likely to cause the decline in the sea otter populations and provides three reasons of support. However, the professor states that the predation hypothesis is the most likely the cause of the sea otter decline in populations and refutes each of the others reasons. First, the reading states that the oil ridgs and other sources of industrial chemical pollution caused the death to the sea otters. The professor opposes this point by saying that the pollution theroy is weakened because people did not find dead sea otter on the beaches of the sea, and that supports the predation theory because if the sea otters were killed because of the pollution, they should wash up to the shores, and that did not happen.

Kitson Jazynka’s purpose in writing Saving the sea otters is just part of her normal day at work is to recount the fact that saving underwater animals are important. Underwater sea animals are dying faster and going extinct,they need our help. Anything that can affect the otters can affect us humans as well and we can help eachother out with this fact. We think that it is important to discover the remains of the dead sea animal, because we care and want to reveal a bit more maybe even discover a new species. Lastly we need them because a species can tell us a lot of information.

Do you think of your body the way you think of your car? When a few lucky individuals acquire a sports car that boasts of the best automotive engineering available today, watch them read the maintenance manuals religiously. They take their car for inspection even if it purrs like a kitten and take it for repairs as soon as something does not feel right. And they're very concerned. That car is their most prized possession, a symbol of all the long and hard hours they put on the job so they could finally acquire it.
