Human beings are heavily 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 both possible and economically feasible.

The past 400 million years of earth’s biological history have been marked by five great periods of extinction, in which the existing life was largely replaced by new forms. The most recent of these occurred some 65 million years ago, marking the end of the Mesozoic Era. Now, evidence indicates that another of these cataclysmic periods is beginning, with one key difference; it will be brought about by humans. In the 150,000 of human existence the extinction rate has risen by a factor of 100, and possibly by as much a...

  • Analysis Of Paul S. Martin's Twilight Of The Mammoths

    1052 Words  | 3 Pages

    In this paper Martin is arguing that late quaternary or near time extinctions where caused by human activity or as he calls it “overkill”. Martin recognizes that there have been many forces that have triggered extinctions in the planet on the past but disagrees with the idea that near time extinctions where caused by some commonly believed causes like climate change, disease or nutrient shortage. He argues that the arrival of humans to different continents, islands and the subsequent excessive hunting, the introduction of diseases and other competitors and predators was the cause of extinction of a great number of species “As our species spread to various continents we wiped out their large

  • Analysis Of The Oil We Eat By Richard Manwin

    For some people the numbers and facts don’t really matter, they read through Manning’s description of extinction and focus on the conclusion he created. Others will focus blindly on the increased extinction rate and rue the day mankind was created. But, there is one group of people who will see “before human domination” (pg. 1) and lose their scientifically accurate minds. Manning is unknowingly referring to the ratio between the background extinction rate and the actual distinction rate, i.e. what scientist think is the extinction rate right now with humans vs. no humans, and referring to it as if it is two completely different rates at two completely different points in time. Small flaws like these are insignificant to the average reader but comparable to kryptonite to credibility from a scientific audiences view. Throughout the essay, these inaccuracies consistently occur, those who know the law of thermodynamics know is not the same as energy transformation in a food-chain and that the scientific method that you simply can’t make conclusions drawn from two different fields of inaccurately portrayed science based on your opinion and call it

  • Adverse Impacts of Landscape Fragmentation on Biodiversity

    2246 Words  | 5 Pages

    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.

  • Neanderthal Extinction

    Neanderthals and modern humans coexisted for well over 100,000 years.  Then suddenly Homo neandertalensis began to die out and surrender the earth to Homo sapiens.  Paleontologists and anthropologists have entertained several possibilities to the causes of this event: interbreeding among Neanderthals and humans, competition for natural resources, and Darwin’s theory of “survival of the fittest.”  What the real cause has been has plagued scientists for years. Now, due to an international research team from Germany, those possibilities have been even further deduced, making it easier to pinpoint the exact reason Homo neandertalensis became extinct.

    Through millions of years of evolution, well-balanced habitats have co-evolved to provide for the wide variety of species and their needs. Trees have adapted to weeds, weeds have adapted to the predation from herbivores, and so on up the food chain. Similar scenarios are seen throughout the world. Through the process of natural selection, specific species or broad species families will go extinct. However, these occurrences have largely been due to the natural flow and evolution of time. It wasn’t until recently that dominant species, such as humans, have taken the course of nature into their own hands.

    Throughout Earth’s history there have been many changes. These changes have consisted of temperature fluctuations, atmospheric differentiations, extinctions of various plant and animal life, etc. Over time everything seems to have evolved in some way form or fashion. However, the Permian Era extinction was different from all the rest. This extinction affected every form of life, but especially the marine life. Researchers have stated that 93-97% of all Earths species went extinct during this period of time. This essay will explain how a once blossoming progressive era turned into Earths most catastrophic event.

  • Poaching: The Cause Of Human Extinction

    The human race has a seemingly impossible challenge before them. While many focus on huge social issues such as terrorism and world hunger, which are completely valid and important issues, many have forgotten about the state of humanity’s neighbors within our very planet. Earth is in the midst of its sixth great extinction, keyed as the Holocene Extinction after the current epoch the planet is in. The Holocene Extinction, starting between 9,000 and 13,000 years ago, is the most recent since the Cretaceous-Tertiary mass extinction, during which the dinosaurs were wiped out (Heymann, Chibante and Brooks). Such knowledge of our current ongoing mass extinction event is not well known among the common populace. The simple fact is that the human

  • The Endangered Species Act

    1890 Words  | 4 Pages

    Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65). As a result governmental and societal action must be taken immediately!

    Various plant and animal species depend on each other for what each offers and these diverse species ensures natural sustainability for all life forms. A healthy and solid biodiversity can recover itself from a variety of disasters. It is estimated that the current species extinction rate is between 1,000 and 10,000 times higher than it would naturally be. Therefore, there is an urgent need, not only to manage and conserve the biotic wealth, but also restore the degraded ecosystems. c) Captivity breeding species can again be reintroduced into the wild.

  • Loss of Biodiversity

    998 Words  | 2 Pages

    Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
