Endangered Species

What is known as the Endangered Species Act began in mid-1960. In order for the Fish and Wildlife Service to expand their efforts to protect endangered species, Congress enacted the Endangered Species Preservation Act of 1966. This Act did little more than allow a list of endangered species to be made. The Act did not prohibit the killing of endangered species or the destruction of their habitat. The lack of legal protection for the endangered species led the Fish and…

Natural Heritage of Singapore

Being a land-scarce country of 714.3 square kilometres and having a population density of 7,257 per square kilometer (Singapore Department of Statistics, 2012), every hectare of land in Singapore is extremely important to us. Over the years, widespread urbanisation has led to about 90.2% of our land area being developed (Tan, 2006), exhausting much of our natural heritage in the process. Due to the limited amount of land, our natural heritage is insufficient to provide us with much economical goods;…

Galapagos Island Case

Introduction Geographical                     The geographical mapping of Galapagos Island is able to support both aquatic life and terrestrial life due to its adverse favorable climatic conditions. This is because this island lies in the Pacific Ocean about 999   km from the South American coast and straddling the Equator. Due to this smart geographical condition, there is abundant biodiversity of both flora and fauna. Galapagos Island is one of 13 islands that is currently inhabited, with a total population of 30,000…

Ecosystem and Major Agricultural Land

Today, biodiversity is exposed to a lot of fatal threats: destruction of habitat, pollution, over-exploitation and climate change. According to Ray Harris (2002), building cities on farmland leads the ruin of territory, for example those in California. He pointed out that nearly half of key major agricultural land in California is filled with buildings. Pearce and Williams (2008) also argued that the large areas of Brazilian rainforest have been wiped out, and this clearing forest for timber is one of…

Importance for Wildlife Conservation

* Maintains ecological balance & the organisms have their unique positions in food chains, food webs which keep ecological balance. * Wild life contributes to the maintenance of material cycles such as carbon and nitrogen cycles. * For improvement and progress in agriculture, animal husbandry and fisheries the genes from wild life preserved as gene bank are utilised in breeding programmes. * Wild life provides a number of useful products like food, medicine, honey, lac, wax, resin, etc. * Colourful…

The Wildlife Biodiversity and Its Continuous Extinction

Wildlife population had turned to be critical through the passing of years since the start of humans to develop its way of living. According to Fornos, “All major wildlife species are now threatened with extinction. ” Different causes had been cited by ecologist that contributed to the deterioration in number of our co-livings in the wild. Deforestation Fairly obvious reason for wildlife extinction is habitat degradation, destruction and conversion (Holsinger, 2005). It is not good to cite that the tropical…

Creation of Ecosystems

Evaluate the relative roles of natural succession and human activities in the creation of ecosystems within the British isles. (40 marks) An ecosystem is a biological community of interacting organisms and their physical environment. Ecosystems can be changed by both human activity and natural succession. Ecological succession is the observed process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after…

Prairie Dogs

“Prairie dogs have a significant effect on biological diversity in prairie ecosystems. More than 200 species of wildlife have been associated with prairie dog towns, with over 140 species benefitting directly…” (Williams 34). Terry Tempest Williams, author of the book “Finding Beauty in a Broken World,” delivers a strong argument as to why prairie dogs should be protected. Prairie dogs contribute to the welfare of animals around them in many ways. They create diversity, kinship and community. Williams also states,…

Ecosystems and Biodiversity

Present paper seeks to provide the comprehensive analysis of ecosystems and biodiversity structure and value for the humanity. The thesis is defended that the balance of ecosystems and maintaining biodiversity are central prerequisites for avoiding the future crisis of biosphere of the Earth. The industrial activities of people negatively affect the mentioned balance and result in deterioration of ecological conditions, which are central for the preservation of life. Ecosystems The nature of ecosystems is inherently structural, systematic and functional. Ecosystem…

Conservation of Biodiversity

Introduction Biodiversity also known as biological diversity is the existence of a wide variety of species (species diversity) or other taxa of plants, animals, and micro organisms in a natural community or habitat, or of communities within a particular environment (ecological diversity) or of a genetic variation within a specie (genetic diversity). (Oxford dictionary of biology). The root of concern for conserving biodiversity are increased loss of species, increased rates of deforestation and soil erosion, shifting of global climate due…

Wildlife_ Biodiversity and Indian Wild Ass

India’s flora and fauna is matchless. In richness, variety and abundance it has hardly any parallel. India’s great latitudinal spread, encompassing a wide range of temperature conditions, makes it rich and varied in flora and fauna. The number of species of flowering plants in the country is about 15,000. There are about 35,000 non-flowering plants. The rich variety of fauna is in direct relation to the abundance and opulence of the flora. Both are inter-linked and interdependent in many ways….

Biodiversity Crisis

As shown by the title, our earth’s biodiversity is at crisis. But some may wonder, what is biodiversity? Wikipedia tells us that biodiversity is the variation of life forms within a given ecosystem, biome, or on the entire Earth. Interesting enough, my science teacher was starting on the Biodiversity chapter when I spotted this poster. We learnt about the classification of species using their common characteristics, but I realize that there are always exceptions. For instance, we know that mammals…

British Wildlife

Outline of species along with related anatomy, handling considerations and rehabilitation, release requirements Skeletal system Although the deer’s skeletal system is very similar to a dog or cat’s in terms of its basic structure, although there are some adaptations that they require in order to survive the wild. Deer have long necks which enable them to crane it so they can feed off low lying grass and other vegetation. Stefoff, R. (2007) Deer are prey animals and so they require…

Biodiversity Museum Exhibit Presentation

Very little is known about biodiversity and its effect on livelihood and the environment. In order to clearly understand where we are coming from a clear definition of the broad concept is in order Biodiversity is the difference in number, frequency and variety of living organisms in an ecological system. This includes plants, animals, birds, fish among others. Basically this term encompasses variety of ecosystems species, and relative abundance (http://www. equalearth. org/wildlifeextinction. htm ). Importance of Biodiversity. Tropical rainforests are…

Reducing Deforestation

Deforestation has been a global problem for the last century. It is considered to be global as every country is facing it nowadays. Deforestation is caused by chopping trees down, in order to produce paper, wooden goods, to expand territory for building houses and roads. The aim of my project is to give an introduction to the problem of deforestation. In my essay I am going to explain why it is global issue, to talk about some ideas how we…
