Biodiversity have three levels - genetic diversity (i.e. diversity of genes within a species and between species), species diversity (refers to the differences in populations within a species, between populations, and between the various species), and ecosystem diversity (refers to the various habitats, biological communities and ecological systems; also denotes differences within ecosystems) (Ecological Society 1997).

An ecosystem remains stable and balanced due to the variety and richness of organisms and species. The relationship of the varied species within an ecosystem has been well documented that destruction or extinction of one species may affect other living things, which may even lead to the extinction of the other species in the ecosystem. Thus, preserving and protecting one species in a particular area is similarly protecting the rest of the species. This is equally true to land-based species and sea and coastal creatures. Biodiversity denotes ecosystem balance and survival of the species within the system.

Generally, the ecosystem remains balanced in its usual natural course. The imbalance occurs when outside elements interfere with the usual processes. Man has interfered with the natural ecosystem for a long time. One form of invasion is by establishing habitation in the coastal areas (Water ecology 2009). It is reported that an estimated two-thirds of the total population lives near or along the coasts (Water ecology 2009). In fact, wetlands and some coastal areas are being dried by people in order to reclaim land for urban expansion (Water ecology 2009). The wetlands are also converted for farming, mining, gas and oil extraction, and highways for land transportation (Water ecology 2009).

Sewage run-off and toxic contaminants (e.g. pesticides, heavy metals) are passed to coastal zones that become concentrated over a period of time (Water ecology 2009). These chemicals threaten aquatic life and biodiversity. Over-fishing of a certain species without proper regulation likewise degrades biodiversity (Water ecology 2009)  ...Download file to see next pagesRead More

...? Preventing Biodiversity Reduction in the Coastal Zone Preventing Biodiversity Reduction in the Coastal Zone Introduction Biodiversity, short for biological diversity, refers to the richness of living things in a particular ecosystem (Ecological Society 1997). It also refers to the broad variation of the “microorganisms, plants, fungi, and animals” as well as the “richness of species of living organisms” (Ecological Society 1997, p.1). The varied organisms and species interact and are interrelated with each other. Biodiversity have three levels - genetic diversity (i.e. diversity of genes within a species and between species), species diversity (refers to the differences in populations within a species, between populations, and between...

Biodiversity Conservation

...?Biodiversity Conservation Biodiversity refers to the variety and assortment of various life forms in the environment. This includes the variety of plants and animals in various ecosystems including marine ecosystems, forest ecosystems as well as grasslands. Biodiversity is very critical to the development of the human species due to food provision, ecological balance and other developmental benefits. However, there are continued threats posed on biodiversity leading to extinction of species. Due to this, scientists have emerged with various strategies to conserve biodiversity and reduce species extinction. This paper will analyze the major causes of biodiversity loss as well as the strategies for conservation based on current scientific...

... Biodiversity Biodiversity is a term that is used to refer to multiple levels of biological organization (Alkemade, Shrestha, and Trisurat 13). These include genetic, species and ecological diversity. The protection of biodiversity is a means of conservation. The biological wealth has been threatened by the need for development leading to the interference with the ecosystem. The process of conservation takes the form of in situ and ex situ. The ex situ approach is the one in which the threatened species are conserved by being removed from their natural habitat. In situ approach entails saving the entire ecosystem to ensure all levels of biodiversity are protected (Andre?e 29). Special settings are established where special care is given...

Beinn Eighe is a biosphere reserve which displays a suite of habitats that are affected by ocean and upland influences. It is characterized by bare rock, heathland, scree and wet grassland. Dwarf shrub heath and western variants moss heath are species that attracts national interest. This biosphere has Loch Maree which is found in isolated gorges which is characterized by holly, rowan, oak and juniper. The site is managed for conservation purposes. It was first establish as an open laboratory which was then used later as a site for managing environmental change. The site is close to Kinlochewe village and it covers about 5,000 hectares. It is surrounded by Loch Maree and Glen Torridon. The site rises to the top of Meall Ghiubhais....

Biodiversity of Coastal and Exposed Shores

...Biodiversity of Coastal and Exposed Shores - A Statistical Analysis By Devangini Mahapatra Chauhan Introduction Biodiversity is a dynamic resource responding to natural and human-induced environmental change. Adaptation to human-induced climate change and sea level rise is likely to be a major driver for biodiversity monitoring. Identifying such drivers of significant change is important, as is the science-based delivery of numerous obligations to undertake monitoring, e.g. favourable condition assessments for sites, biodiversity targets, assessment of policy objectives, EU Habitats and Birds Directives, Convention for the Protection of the Marine Environment of the North- East Atlantic (OSPAR), EU Water Framework Directive etc. (DETR...

...Answer The population dynamics have become the most important factors in the national and global politics. In the era of the fast advancing technology and rapid globalization, population plays a vital role in the overall socio-economic growth of the nation. According to UNFPA’s 2007 report, in July, the world population reached 6.7 billion. Population growth in the last quarter of the century saw an unprecedented increase in population bringing new challenges in its wake. ‘It took 1800 years to reach a total population of 1 billion, but only 130 years to reach 2 billion, and a mere 45 years to reach 4 billion’ (Farabee, 1995). Looking at the statistics, it is observed that human population does not follow the logistic growth... The population ...

Coastal Zone Management Policy

... the coastal zone management is very important for every nation. Importance of coastal zone management: In today’s world, with the changing climatic conditions globally and with the green house effect it is very important to maintain the coastal waters. The earth is made up of 75 percent of water. The coastal region is less than fifteen percent in the world but it holds more than fifty percent of the world population in it. It is also one of the major natural resources which add to the wealth of the nations. Management measures must be taken for control against erosion, sedimentation, to retain the nutrients etc. It is also important to understand the behavior of the coasts and prevent them from being destroyed either by natural sources...

...Factors Causing Loss of Biodiversity and the Consequences Biodiversity Cardinale examine the effect of the current loss of biodiversity on humans. The central argument in the article states that humans are responsible for the global loss of biodiversity through their activities and in the event that the process continues, they will bear the largest brunt. Starting off from the 1980s the authors study the rate of biodiversity loss and the effect that it has heard as well as possible further consequences. From the study, some of the resultant aftermaths of the loss of biodiversity include lack of efficiencies by which ecological communities capture biological resources, instability in ecosystems and future environmental changes among...

Answer one According to Genesis, in the story of creation, man was formed from the image of God. God made man and gave him control of all other living things on earth. For instance, man was given power to name the creatures of the earth. Man was created in the likeness of God. Arguably, man is the next species to God.
Answer two
The purpose of the book is to change the perception people have about the earth processes and the environment in general. According to the Mark Lynas, there is unprecedented environmental degradation that is caused by the fact that humans are in control over most of these earth processes. He continues to observe that introduction of science to manage the environment may be futile. The cases of genet...
