Argumentative Essay About Penguins

The installation of a Barn Owl box provides Barn Owls shelter, so they can reduce the rodent population there for food (Williams 1). This also decreases the risk of Barn Owls, as well as other nontarget animals, from being poisoned by rodenticides because less rodenticides are utilized. In addition, in order for a box to be installed, the property in which it will be placed cannot have used pesticides in the last 3 months (“Nesting Boxes”).

While domesticated pets like dogs and cats make good pets many people want to own exotic animals that belong in the wild. These animals range from tigers to pythons, but should not be owned as they need special care most people cannot provide. Not only this, but exotic animals release is harmful for everyone, the exotic animal, humans, and native animals. Lastly, many exotic animals carry diseases that are harmless to them, but fatal to humans. Exotic “pets” are harmful for everyone, not just the pet. This is why people should not be able to own exotic pets.

Every child has asked their parents for a pet animal. The thing is though, is what type of animal they asked for. Such as a dog or cat and even the occasional hippopotamus for Christmas, right? Lots of people buy exotic animals not knowing how much work it really takes to take care of them. For example, many people have bought pythons and when they get to a size where they can’t keep care of them they let them go into the wild. Exotic animals are very costly and time consuming, they grow up and get bigger and all in all they are very dangerous.

The article I found is about the endangerment of african penguins. The african penguin is endangered, and many laws have been put into place in South Africa to protect them, mainly preventing fishing so they have a stable food supply. The article talks about how fisherman are a big cause for the penguins dying out, and how the prevention of fishing has greatly increased their population. However, despite all the efforts to protect them, it still isn't enough to get them off the endangered species list. The penguins still face many dangers like water pollution and climate changes that destroy their habitats. African penguins also had a 90% decrease in population size from the 1930’s to early 2000’s. However in the last 10 years the population

In the past twenty years, the world we call our home has changed, and continues to change, drastically:

To begin with, if the Galapagos Penguin were to become extinct, it would harm the ecosystem detrimentally, specifically the food web. In the food web of the Galapagos Islands, the Galapagos Penguin is the second order consumer as it feeds 0n smaller fish. If it were to become extinct, the population of the first order consumer (small fish such as mullet and sardines) would dramatically increase causing the producer to decrease and slowly die out. This will also impact the other first order consumers as there will be less food to share amongst them slowly triggering their extinction as well. Overall the extinction of the Galapagos Penguin will completely put the local ecosystem out of balance.

Penguins ( family Spheniscidae, order Sphenisciformes) are a group of flightless, aquatic birds living exclusively in the Southern Hemisphere, particularly in Antarctica. Well-adapted for life in the water, these birds have countershaded white and black plumage, and their wings have evolved into flat, paddle-like flippers. They feed on squid, fish, krill and other forms of sealife. Penguins spend half of their lives in the oceans and half on land. This list contains 10 unusual facts about penguins you may not know.

Should animals in Captivity be allowed? Animals in Captivity should be allowed because they get the medicine they need, animals can live longer, and the animals can get smarter. The first reason animals in captivity should be allowed is that animals can get healthy. There are rehabilitation programs that nurse animals back to health.Veterinarians can prevent and control a disease. Second, animals can live longer in captivity. In the article, by Hannah J. O’regan and Andrew C. Kitchener states, “Gorillas live for more than 50 years in captivity compared to 35 years in the wild” (223). The animals diets also help them live longer. Lastly animals can get smarter. Animals in captivity do more activities making them smarter. For example, “Rats raised in enriched environments had larger brains”(O’regan and Kitchener 224). Animals in captivity should be allowed because they are able to get healthier, their lifespan increases, and they get more intelligent.

My name is Zachary Rowe, I am going to talk about the global warming weather effects in Alaska and how it has affected the population of various living animal species. The number of large predators living in the southern Beaufort Sea of Alaska has decreased from 1,500 animals in 2001, to just under 900 in 2010. As the species are decreasing in numbers, they are now listed as vulnerable by the International Union for the Conservation of Nature. Another problem in 2013, a report by the National Oceanic and Atmospheric Administration have seen a decline in reindeer inside Alaskan boundaries. These aren't the only species whose populations has

For this week’s forum, I choose to talk about the bald eagle. The scientific name for the bald eagle is Haliaeetus leucocephalu and comes from the accipitrine family. With the bald eagle growing three feet tall had having a wing span of seven feet, this magnificent bird has few predator’s. Crow’s enjoy harassing the bald eagle, but pose very little threat. Animals such as the; great horned owl, squirrels, raccoons and ravens will try to snatch the eggs from the nest of the bald eagle. The one major predator of the bald eagle is humans, in the past farmers would kill eagles to protect their crops and livestock, bring the eagles almost into extinction. The bald eagle is no longer on the endangered species list, but it’s still illegal to

Emperor penguins are majestic creatures; their life cycle portrayed in the film "March of the Penguins" shows a lifecycle fraught with dangers, including exposure to extreme environmental conditions and aggressive predators. Despite the challenges, the breed has survived. It may be argued that survival is the result of natural selection and the adaptations which have developed, but it is also argued luck plays a role.

“Penguin responses to climate change in the Southern Ocean” by Jaume Forcada and Philip N. Trathan (2009) was a study conducted to analyze and predict the migrating patterns of different species of penguins due to changes in climate. (p. 1618) Also, Forcada and Trathan investigate whether or not certain species of penguins possess phenotypic plasticity (the ability of an organism to change its phenotype in response to changes in the environment) (p. 1618).

Northern Pike are a big predator in a lake's ecosystem, and a fear to countless fish.

Sea ice is a vital breeding and nursing habitat for emperor penguins, where their colonies are formed far from the open sea. The breeding penguins, would then, go on scavenging trips throughout the entire development and chick nurturing stages. However, during the period with thick and wide sea ice cover, the trips become longer. Adult penguins would have to use up more energy for travel, which will result in lower offspring provisioning and hatching success (Barbraud & Weimerskirch, 2001, p. 185). Also, sea ice could influence the emperor penguin by “topdown processes”. Diminished sea ice could allow access to hunting areas of the emperor penguin by potential predators, such as killer whales (Jenouvrier et al., (2012), p. 2759). Consequently, there are no emperor penguin remains found in killer whale diets. Nevertheless, penguins that have used up so much energy (especially males after their 4 months fast) are vulnerable to other predators, which could result in a lower survival rate. This predicament is mainly caused by the change of variables called “sea ice concentration” and “sea ice

Our Iceberg is Melting by Holger Rathgeber and John Kotter tells a tale of a colony of penguins and their journey in planning, organizing, and changing their traditions for the safety of everyone and future generations. Five penguins by the name of Fred, Alice, Louis, Jordan, and Buddy, who have completely different personalities must work together as a team to find a solution to their disintegrating ice cap and overcome the obstacles that come along. As each penguin uses their skills and abilities to the team’s advantage, they are able to come up with a plan to save their colony from the catastrophe they will face from their melting home. Finally, the crew is able to persuade the entire population that becoming nomadic is the best
