Biodiversity is commonly described as the variety and diversity of life on Earth. “The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth” (Shah, A. 2012). In fact, Earth is made of complex ecosystems’ interacting with each other’s, giving life to any and every species, impacting on climate, human and animals’ lives
environmental cost of globalization is habitat loss and degradation, which further leads to the accelerated extinction of wild species and the collapse of biodiversity. Thus, terrestrial protected areas and international agreements are necessary to preserve habitat and halt biodiversity loss. The collapse of biodiversity would be one of the most serious issues that result from globalization. As remarked by Scholte(as cited in Hansen, 2010), the extinction rate has been exponentially increasing since
Biodiversity is the variation among living organisms in different ecosystems, and is the result of 3.5 million years of evolution. Evolutionary diversification, offset by extinction events, is responsible for the continuous increase in biodiversity over the course of Earth 's history, from unicellular organisms to the creation of millions of multicellular organisms. Evolutionary diversification leads to the process of speciation, creating large variation between species in terms of evolutionary age
Introduction Biodiversity , a word derived from biological diversity , is the variety of all life forms: the different plants , animals and microorganisms , their genes and the communities and ecosystems of which they are part . Biodiversity is usually recognised at three levels : genetic diversity , species diversity and ecosystem diversity . Biodiversity loss is the local or global extinction of an allele or species .(Steffen,2009) Austrlia is separated from other countries so when the biodiversity loss
BIODIVERSITY Biodiversity is made up of two words that is biological and diversity. Biological word is related to life and diversity is linked with variations or changes. In simple terms, we can say that biodiversity means the variations in life. Biodiversity is defined as whole life that exists on earth planet including animals , plants, fungi and micro-organisms as well as the associations among them including their eco-system (IUCN, 2010). Classification of biodiversity The biodiversity
Biodiversity Greenwald, N. (n.d.). . Retrieved October 21, 2017, from http://www.biologicaldiversity.org/programs/biodiversity/elements_of_biodiversity/ In this article, the author describes in the first section what biodiversity is and where it is located around the globe. They begin to explain that biodiversity is a variation in species of all types of biological areas, it focuses more on the array of differences between the species. The more biodiverse an ecosystem is the greater the chance it
single living thing in the planet. Biodiversity is important because species, as a part of it, plays an important role to maintain a healthy ecosystem. For further knowledge, Biodiversity is everywhere, it can be on land or water. It starts from microscopic bacteria to the most complex plants and animals. Biodiversity supports the way ecosystem function and provides services such as water and nutrient cycling, regulation of climate and pollination. Now, why is biodiversity important to us? It satisfy our
is being realized, bitterness and distastefulness fills this human mouth as we will be witness to the “modern human-induced,” sixth mass extinction of species. From Ceballos G, and his assessments Ehrlich PR, Barnosky AD, Garcia A, Pringle RM, and Palmer TM, they have strictly proven, through very narrowed, factual, precise data, that proves that the extinction rates are higher than before due to of human activity. He establishes his data referenced on being conservative to not be accused of exaggerating
reliant on nature’s biodiversity. This biodiversity, however, is threatened by accelerating extinction rates which are approaching past mass extinction levels. Human activities are largely responsible for this trend, and, while there has been some success in preserving select species, the scale of the impending extinction will necessitate the conservation of existing ecosystems if biodiversity is to be preserved. Fortunately, the relative geographical concentration of most biodiversity makes such efforts
Biodiversity can be defined simply as the variety of life and can be studied on many levels (National Wildlife Federation, 2014). Understanding how to measure biodiversity and the problems associated with the methods used is a key factor that needs to be considered. Investigation into areas where biodiversity is decreasing will show how and where the decline in biodiversity is taking place. But the areas where management and natural recovery is taking place cannot be ignored, as they show an increase
