Humans have always used wild animals and plants for their products, such as fruits and seeds for food, skins for clothing, wood for fires etc. Apart from its use for basic needs, wildlife has also been exploited for luxury items e.g. ornaments and fashion. At one time, when there were far fewer people on Earth and a lot more wildlife, such exploitation did not have any significant effect on the overall numbers of animals and plants. With over six billion people in the world today the situation is now very different. Today more and more wildlife is becoming extinct in the wild for various reasons such as habitat loss, pollution, human intervention, and commercial use of wildlife . All human societies use wildlife directly and/or indirectly. As a result of pressure from an ever-increasing human population, many species of animals and plants have been greatly reduced in numbers and they will not survive for much longer if we continue to kill them for luxury items. Modern technology and knowledge means that we can manufacture or find substitutes for products from endangered species: plastic for tortoiseshell or ivory, jojoba oil for whale oil, synthetic drugs for rhino horns and tiger bones. We can live very happily without leopard-skin coats, mahogany furniture, and turtle soup or pet orangutans. Humans have not utilized natural resources, including wildlife, in a responsible manner, so ecological processes cannot continue to function and sustain a diverse and healthy environment for the wildlife population.
Conservation and management of wildlife is undoubtedly a very complex issue, which encompasses a wide range of implications for local communities, tourism industries, national economies, and our world heritage. How...

...be a portion of the planets poorest nations, yet wealthiest in biodiversity. For these nations, fares of endangered species and consequent items speak to a noteworthy supply of outside money income. Exchange presents both a chance and a danger. A high extent of the world's populace is specifically subject to wildlife for utilization, and additionally for a wellspring of pay. From a natural angle, populace exhaustion and species elimination debilitates biodiversity. Repercussions develop past the endangered species, the same number of the creatures and plants uncovered by worldwide exchange go about as "umbrella" or "keystone" species in their individual territories. Moreover, given the multifaceted nature of environmental frameworks on the micro and macro levels, evacuation of a species from the framework may have both unforeseeable and undesirable consequence.
Landscape fragmentation contributes to loss of migratory corridors, loss of connectivity and natural communities, which all lead to a loss of biodiversity for a region. Conservation of biodiversity must include all levels of diversity: genetic, species, community, and landscape (CNHP 1995). Each complex level is dependent upon and linked to the other levels. In addition, humans are linked to all levels of this hierarchy. A healthy natural and human environment go hand in hand (CNHP 1995). An important step in conservation planning, in order to guarantee both a healthy natural environment as well as a healthy human environment, is recognizing the most endangered elements.
Although the assessment displayed many threats, this project will address only one causal chain: of the inefficiency of co-management agreement in the park. The contributing factors for this direct threat are first, the lack of revision of the agreement since 1991. The last stage of the co-management agreement inside of Kakadu National park was signed 27 years ago. Although this co-management agreement has been through different stages and revisions, very important aspects of the context have changed since then. It is proposed in this project that a revision is needed to assure that the agreement has both benefits for traditional owners and to wildlife in the park. Secondly, currently, there are conflicting agendas and conflicting definitions of the problem within the participants. This has created for different programs and policies to be created, often in conflict with one another. For example, wide-range poisoning of quolls by traps to kill dingoes implemented by one agency that seeks to exterminate invasive species (such as wild dogs/dingoes). Another example of what different problem definitions can create is the foxes example. An agency can see foxes as the main issue, and the solution is to target foxes with poisoning bait. What happens, then, is numbers of feral cats and rabbits, which are also hunted by foxes, tend to boom once the foxes are gone. So, small marsupials (i.e. quolls) will still be hunted – only by cats instead – and the rabbits will wreak havoc in the landscape, depriving native animals of food and shelter. This connects to the third contributing factor, the multiplicity of agencies, and lack of exchange between them. Because Australia works under the frame of a decentralized government, many agencies and organizations do not communicate with each other or are held accountable. This then creates a very complex social process, which then creates a very
Extinction is no longer just a natural process. It is an enemy, slowly changing our world into a barren wasteland where life is as rare as a flower in the Arctic Circle's winter. The wolf, the tiger, the caribou, the elephant, the bison, the cheetah, the sequoia cactus, the redwood tree – all of these and so many more things are on the verge of disappearing from our planet forever. Extinction is the most pressing environmental issue of our time, because if it continues the way it is going without anything being done to counteract its causes and consequences, there will soon be no environment left for there to be debates about.
In the beginning of the 1800’s it is estimated that there were 26 million elephants roaming our planet. At that time many animals were at their peak, were thriving; to understand just how drastically humans have impacted the elephant population it takes looking at the sharp decline. Starting in the early 1900’s to hunt down an elephant on an African safari was seen with high esteem. As time went on ivory from the elephant’s tusks began to be sold largely for piano keys, pool balls, brush handles, and combs. As popularity of these commodities rose mass production increased and soon in 1913 the U.S. alone was importing 200 tons of ivory each year. To put into perspective just how sharply the population dropped from the early 1900’s the population started out around 10 million and in 1979 it was estimated to be at 1.3 million.
It is difficult for humans to live in harmony with nature because humans’ selfishness always places profits before our earth’s needs. We live in a consumer society, which we purchase interesting products and dispose of them carelessly. Those products with non-decomposable materials, which make our life easier and more comfortable, result a massive damage to our environment. In the articles, “A Fable for Tomorrow” by Rachel Carson and “Our Animals Rite” by Anna Quindlen, both authors suggest destruction in nature world due to human’s activities. As environment issues presented by scientists, governments around the world start to give highly attention on the environmental protection, but there are many challenges in implementing environmental protection policies. Some of the top environmental concerns are air pollution, climate changing and trash waste. Although people started to aware the horrible consequences due to polluted environment, an efficient life, people apathy toward ecosystem and human's unlimited desires for a confortable life have created obstacles for the world to protect the environment.
The ecosystems around the world are vital aspects of our everyday lives. Without the many resources and materials we harvest or use, life as we know it would be drastically different. In modern society, money is prioritized over essential benefits from nature. Due to this unfortunate truth, the stability of the environment has decreased on a global scale. Several of these issues include pollution, destruction of habitats, and causing species to go extinct due to events such as overfishing. Another human-caused problem is deforestation, particularly in the Amazon Rainforest.
My first point, feeding wildlife disrupts natural cycles. Wild animals will learn to come to humans for food. If constantly rewarded with food when they approach humans, animals will learn how easy it is to gain food, and move out of their natural habitat into human populated areas. Their natural ha...
are at a very high risk of extinction. There are over 3000 endangered species around the world due to many factors including over-fishing, hunting, destruction of habitat, climate change and a decrease in food supply. As the number of endangered species are increasing quickly it is very important that action is taken to preserve them for a number of reasons. If endangered species are not preserved it could easily lead to the species becoming extinct which could upset the food chain and lead to further extinction of other species. This could have not only negative effects on there predators but would eventually lead to having negative effects on species further up the food chain including the human species. Over the years researches have come to discover and find that all species play an important part in looking after our ecosystem and extinction could cause a big hole in the system.
Humans have been hunting practically since the beginning of time. Take a moment to look back at our country’s founding fathers and Native Americans. People in that era hunted as a means of survival. We all possess the skills of stalking prey. It’s in our blood. Hunting is automatically instilled in us being at the top of the food chain. Although looking back into history, one can also find that some hunting has diminished animal populations practically to the verge of extinction. However these facts have not gone unnoticed. If hunting is well regulated, whether it be for sport or recreational involvement, and there are no major affects to the species, if anything it may help bring back species from the edge of extinction. “Several wildlife managers view recreational hunting as the principal basis for protection of wildlife.”(Lebel)
Loss of biodiversity is an environmental issue that is causing a lot of global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth. There are measures that are being taken worldwide to prevent loss of biodiversity. Many wildlife sanctuaries have been built worldwide to preserve the lives of various endangered species. However, it is important to remember that every individual has a role in the protection of wildlife and biodiversity. Every human being should play his part of the role by following simple rules such as stopping others from the hunting of endangered species, preventing deforestation, encouraging reforestation and creating awareness among fellow human beings.
Everyone’s all seen those wildlife shows on tv. The shows on National Geographic and such, showing animals in beautiful environments, everything lush and growing and nothing at all wrong that could threaten these creatures and places. But, have anyone seen the other side? The side where all these beautiful creatures and plants starve, are decimated by predators that have never been there before, and sometime even become poisoned by their very own homes and habitats? Of course no one has. That doesn’t mean that its not happening. It is happening, and its happening everywhere. And guess who is to blame? People. Society. Humans as a race pollute the environment, hunt animals simply for their parts, fish way more than humans will ever need just for the sake of money, introduce new species to new places for our own gain, and even purposefully destroy entire regions just for human expansion. And its starting to take its toll. While it is true that nature is constantly in flux and certain species come and go, humans are causing more species to disappear in the past few hundred years then nature has ever caused since the age of the dinosaurs, and therefore it is up to humans to repair the damage caused, be it cleaning the environment and habitats of these creatures, or taking more direct action to protect and preserve the species that are on the brink of extinction.
Some main causes of Endangerment are habitat loss, pollution, hunting, competition from non-native plants and animals, plant collecting, logging, clearing forests, and trading animal parts. The growing population also causes some effect because man cause most problems. Diseases or viruses are al...

The degradation of ecosystems and loss of biodiversity is increasing at an alarming rate every year. Humans are certainly not the only reason for this, but they are the main contributors. The well-being of ecosystems affects our everyday lives - consumption and consumerism depend on natural resources. Everything humans use is derived from them, in seemingly indirect and direct ways. Yet despite the fact that humans are destroying the environment, many continue to and neglect to take important measures to protect it.
NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY: Biodiversity, a contraction of “biological diversity,” generally refers to the variety and variability of life on Earth. The very existence of human species and sustainable development depend on biodiversity conservation, therefore the need for conservation of biodiversity is basically for this reason that all living creatures need other creatures and plants in one way or the other. At least 40 per cent of the world’s economy and 80 per cent of the needs of the poor are mainly derived from biological resources. Biodiversity is necessary for our existence as well as valuable in its own right as it provides the fundamental building blocks for the many goods and services which are essential
