Did you know that zebra mussels cost the economy 5 billion dollars a year? 5 billion!? The zebra mussels are an invasive species that came from Europe to the states. They attached to boats and traveled there.
Is using Native Americans as mascots for sports teams offensive? It does not matter if it is a high school or a college, sometimes even the NFL. Examples of sports teams that use Native Americans images are Washington Redskins, Florida State Seminoles, and a high school Cherokee Braves. It is not offending and there should not be any problem because it is not making fun of anybody. Using Native American images and names in professional, collegiate, and high schools sport teams does not reinforce and perpetuate stereotypes because it symbolizes their culture, shows that they are ready to play, and appreciates their coexistence.
Marine parks in the country like SeaWorld, have orcas in tanks that they live in captivity. They use most of the killer whales for their performances in the pool. We all know that orcas are social, and intelligent creatures, that live in the oceans of the earth. We also know that many scientist are trying to study these animals in captivity where they are in tankes. I think Killer Whales should not be in captivity because, of the injures they can get in their tanks, how they get stressed out and they are better in the wild.
This one explanation full illustrates the importance of a balanced ecosystem and how the introduction of a predator can make sweeping changes in the
Something that had one of the biggest impacts on the world as it is today is colonization. There’s no way that the world we live in would be the same without it. From colonization, a multitude of good things came out of it, such as wealth for many nations, new land discovered, and colonies established. However, all of those things came at a price to others. The negatives of colonization affected the Native Americans (North, South, and Central America) and the Africans.
According to the World Wildlife Fund for Nature organization, the Mojave Desert ranks as the smallest desert among the four existing in America. Just like any other desert, it faces numerous threats to its wildlife and environment. An example includes the introduction of invasive species into their territory. The University of Nevada agrees that the invasive plant numbers are growing mainly from the results of human disturbance, which is a tremendous issue that can harm both plants and animals. Invasive species affect the diets of desert animals, their existence, and the populations of native plants.
Have you an american citizen thought about all the hard work undocumented immigrants have to do just to become an american citizen? Undocumented immigrants are humans just like us they have the right to chase after their dreams so why not let them. About 11million undocumented immigrants are here in the U.S most of them are here to find a good job and give there kids/family the opportunities they deserve to become someone in life. What all Undocumented immigrants want is for their families not to be torn apart, keep the american tradition and help the economy get better. One important reason that Immigrants should get a path to citizenship is that they help keep the American tradition.
I believe that the Japanese and the Norwegians should be allowed to hunt non endangered whales and that they have a right to claim a cultural exemption. But this exemption should only be from within their own territorial waters where they would have to manage their coastal stocks. The Japanese traditionally did their whaling close to their own coastal shores (Whaling in Japan, 2016) and have been doing open boat whaling since the 12th century (Whaling in Japan, 2016). It was the depletion of their stocks that pushed them out into international waters.
Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
Illegal immigrants should be allowed to stay in the U.S.A. and become citizens because they are heavy workers, want a better life and most importantly they contribute to the U.S. economy. Immigrants simply want to obtain an opportunity to live and work in this great country. With all this in mind it is clear that they deserve a path to citizenship. Countless people say illegal immigrants are damaging the U.S. economy; however, they are contributing immensely by paying their taxes.
Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive.
Poaching: Daniya Toor #21 Class: 8B Definition: What Is Poaching? To illegally hunt or catch (game or fish) on land that is not one 's own, or in contravention of official protection. Causes: Animal poaching is caused by illegal hunters that hunt endangered animals or animals in a protected area. Even hunting animals when they are out of hunting season is considered poaching.
All living species should be treated with care and respect, no organisms should be made a commodity for the sake of human interest. Exotic animals, which are unusual or rare species such as lions, tigers, and non-human primates – are nowadays kept within households as pets. However, according to research, 98% of the people believe that exotic animals should not be kept as “pets”. Such opinions are due to several reasons that are sometimes supported and other times opposed.
Wildlife Conservation is often seen as a bad thing, but if you look at it from my perspective, then it is actually a good thing. People think of it as holding wild animals captive, but we are actually protecting them from poachers. The purpose of Wildlife Conservation is to protect the animals in danger, which I am in agreement 110%. Other people argue that we shouldn’t have conservations, but they don’t know the harm that can happen to unprotected animals.
Zoos have been around since the eighteenth century. A zoo is defined as a compound where wild animals are kept for viewing and studying. The purpose of a zoo is mainly for education and protection, preserving animal species that are either at a risk of becoming extinct or for increased collection size (Jamieson). Animals from around the world have been enclosed in an area where we can admire and study these fine creatures. However, many modern zoos around the world have introduced animal shows, petting and feeding sessions to attract more visitors in order to earn more money.
