Once widespread throughout the grasslands and savanna of northern Africa, dama gazelle (Nanger dama) populations have dramatically plummeted in recent history. The species is categorized as critically endangered by the IUCN, and remaining populations are fragmented and limited to small areas in Chad, Mali, and Niger (IUCN 2014). The dama gazelle species is classified into three subspecies: addra (N. d. ruficollis), the mohor (N. d. mhorr) and dama (N. d. dama), which differ in geographical distribution and coat color (IUCN 2014; RZSS and IUCN 2014). Remaining wild populations are highly fragmented and species survival is threatened by habitat degradation and loss, primarily due to overgrazing by domestic species, use of land for agriculture, and poaching (Grettenberger and Newby 1986; Newby 2014; RZSS and IUCN 2014). Current predictions suggest climate change will significantly impact the remaining habitat and likely negatively influence survival (Durant et al. 2014; Bronson 2009; Zerbe et al. 2012). In addition, spatial segregation of remaining wild populations increases possibility of inbreeding and concomitant decline in reproductive success (Roldan et al. 1998; Gomendio et al. 2000; Andrabi and Maxwell 2007). The ex situ population of addra gazelle also is not self-sustaining and individuals managed in captivity are dispersed across North America in small herds, hindering their effective genetic management.
Maintaining sustainable populations of threatened non-domestic
Most people in America have never thought about where their food comes from or even talked to a farmer or rancher. Of that handful who have, even fewer have ever stepped foot onto a farm or ranch.The film “Farmland” takes an interestingly angled look into the lives of six farmers and ranchers in their twenties who are all entirely responsible for their operations. This paper takes a more in-depth look at three; Ryan Veldhuizen, Sutton Morgan, and Margaret Schlass.
The cultivation of rice has had an enormous impact on the natural biome. Rice has affected the natural biome that it is grown in, in a devastating way. It has caused the natural biomes to deteriorate and caused the natural way of life to collapse leaving no place for the native animals and plants. But what would happen if the cultivation of rice stopped and the natural biomes returned to their former glory? What would happen to all those people depending on rice for the next meal? Those who depend on rice to pay for and keep their families alive? This report looks at the where, effects, who and how of rice cultivation.
With only two hundred and fifty to three hundred left, the critically endangered Cross River Gorilla roams the African forests while on the brink of extinction (Save Our Species). Africa has many populations of primates that are at the least endangered, and the Cross River Gorilla is the closest to extinction and the least studied due to the rarity of observing them. (Save Our Species). These gorillas are confined to small, mountainous areas that have been separated over and over again by fragmentation, furthermore ruining the needed social aspect of the groups and need for vast land (Imong, I., & Robbins, M.), (Save Our Species) The increased hunting and fragmentation of these Gorilla’s habitats has caused a large problem with how the
Elephant populations suffered a drop in numbers that carried the species into the endangered animals list. At the beginning of the twentieth century, about ten million elephants lived in Africa. Presently, the ten million is reduced to half a million because of illegal hunting and habitat loss. Studies of the population show twenty-two thousand were killed in 2012 and twenty-five thousand in 2011. When comparing the death rate to the natural population growth, there is a possibility the largest mammal on Earth could be extinct soon (Vaughan 1). Because the elephant is the largest animal to walk on land, the greatly increasing human population affects the elephant population first. They live in some regions of the world that have the densest human population which continues to grow, which therefore continuously decreases their own population (Bryner 1). As the human population swiftly increases, the elephant population in turn, decreases. This is so because they cannot cohabitate the same living space. Elephants and humans cannot cohabitate because they would kill each other due to the inability to communicate. About population recovery, the Animal wildlife foundation states, “Populations of elephants- especially in Southern and Eastern Africa- that once showed promising signs of recovery could be at risk due to the recent surge in poaching for the illegal ivory trade”(1). Poaching presents one of the main issues that make recovery so difficult for these animals.
Last, many endangered animals are becoming more at risk because of the climate change. The habitats of several endangered animals have started to disappear, and their water has become scarce, too. Document B says that these animals include snow leopards, whose forest climate is shrinking, one-horned rhinos, whose vegetation is being diminished by regular droughts and floods, and orang-utans, who are being killed in forest fires in their forest homes. This killing of endangered animals is bringing these species closer to extinction all because of the rise in earth’s
Conservation of our biodiversity not only demonstrates foresight, it protects the natural resources so vital to our own continued existence. The value of any single species to an ecosystem is immeasurable; the environment will not endure without its species, despite size or niche. These animals are not dispensable. And, they are apt to face extinction in the not too distant future, unless a resolve for their preservation is insisted by the public and enforced by governments internationally.
Plaintiff, Kaycee Land and Livestock, opened a case to hold Defendant, Roger Flahive, personally liable for (contamination) damages after an agreement made by Flahive’s LLC, Flahive Oil & Gas. The District Court of Johnson County presented the case to the Supreme Court of Wyoming to determine if Flahive could be held personally liable. Kaycee Land and Livestock contracted with Flahive Oil & Gas in order to use the surface of the land to raise the Plaintiff’s livestock. Kaycee Land and Livestock claims that Flahive Oil & Gas contaminated the surface area, leaving it useless for Kaycee Land and Livestock’s needs. Flahive Oil & Gas does not have any assets. Therefore, Kaycee Land and Livestock wants to use general corporate veil-piercing principles
Animal extinction is big a threat to some animal species. According to the text “ The Impact of Animal Protection”, many nature parks have supervised breeding programs that allow numbers to increase. Many people think that animals should be able to repopulate by themselves. Keeping animals protected has proven to be beneficial and increase the populations of endangered animals. According to the text “The Impact of Animal Protection” these programs have helped bring several animals - black footed
Captive breeding and reintroduction, translocations, population size estimates, inbreeding depression and avoidance, disease resistance, hybridization between introduced and native species, climate change and adaptation.
The book includes a clear outline of the history of conservation in Africa, coupled with stories of Africans involved in conservation management. The authors explain the issues around African conservation as well as including their own input and potential solutions. One of the main points presented is that the myth that Africans and wildlife being incompatible must be broken. It is evident that Africans are just as passionate about their wildlife like the rest of the world and the authors try to bring this across to the rest of the world. However, conservationists must make sure that rural people are acknowledged and that they engage in conservation efforts to make sure projects are successful. Due to the age of the book, several issues are more prominent than others, such as habitat loss and overpopulation, and that the solutions to these issues will have changed with the development of technology. Public awareness and the education of issues are now more achievable and effective due to the advancement in communication in the form of social media and the fact many Africans own a mobile phones. The involvement of local communities will always be important in conservation and most of the points brought across in the book about the past will remain relevant.

Is animal husbandry in Texas sustainable in relation to fresh water use and water contamination?
Bill Freedmen, author of “Endangered Species—Human Causes Of Extinction and Endangerment” notes, “scientists approximate that present extinction rates are 1,000 to 10,000 times higher than the average natural extinction rate.” These distressing numbers should be acted upon to save the endangered species and avoid the catastrophic change to this planet if these species were to become extinct. In order to produce change, people need to recognize that habitat loss, climate change, and poaching are all factors in why our animal species are going extinct.
The African Wild Dog, or Lycaon pictus is currently under the endangered status, and poses as a huge concern for conservationist groups. The species has become endangered due to human development, habitat fragmentation, and disease such as canine distemper, which has caused a drastic reduction in population size to less than 6000 individuals remaining in the wild. This loss of this species, which is currently only found in several southern countries of Africa, serves as a large threat to the functioning of it’s ecosystem. Lycaon pictus serves the role of keeping several species population sizes in check via predation, but also serves as the source of food for several other species. One conservation plan that has been proposed is the preservation
The seven concepts of geography are used many times by geographers and each concept plays a key role in landscapes and landforms. Space, Place, Interconnection, Change, Environment, Scale and Sustainability re all the 7 concepts geographers use. The landscape 'Princess Margaret Rose Cave ' is arguably the most attractive cave in Victoria and in the cave the 7 concepts are involved.
Agriculture in the United States has changed dramatically over the centuries. Since the 1960’s large commercial farms have been leading in sales. As a direct result of their success we, as a society, have access to affordable food. However, the success of large farms has lead to many negative impacts such as increased usage of resources and decreased diversity in crop fields. This begs the question, what can be done to reduce the negative impacts of large farms. One solution growing in popularity is sustainable agriculture. The idea of sustainable agriculture is to create farms that need little to no outside help from irrigation, pesticides, or fertilizers. Sustainability can be achieved in many way through
