Declining biodiversity speeds spreading of disease new research details how a loss in biodiversity more often than not increases the transmission of disease as humans have disrupted ecosystems. According to the world wildlife federation, biodiversity affects humans in terms of natural resources and ecosystem services the federation points out that biodiversity is a foundational issue for all life on planet earth. Human activities are causing an alarming decline in the variety of plant and animal life on earth and jeopardizing food, clean water and energy supplies, a un-backed study of biodiversity said on. Global biodiversity decline (gbd) is a collapse in the number and variety of species on the earth, specifically caused by humans while biodiversity extinction has been known to occur over the past years, the current gbd is unprecedented in both its scale and scope. The decline of biodiversity might lead to a faster rate of emergence and re-emergence of infectious diseases, such as the hantavirus, and therefore the infection of a greater proportion of the human population (keesing et al 2010.
The major causes of biodiversity decline are land use changes, pollution, changes in atmospheric co 2 concentrations, changes in the nitrogen cycle and acid rain, climate alterations, and the introduction of exotic species, all coincident to human population growth. Biodiversity decline in the region is a very complicated phenomenon that needs to be tackled through a mix of policies and incentives in the recent past, the proximate causes of biodiversity loss, such as logging and biofuel expansion, have received the most attention. The loss of biodiversity has many consequences that we understand, and many that we do not it is apparent that mankind is willing to sustain a great deal of biodiversity loss if there are concomitant benefits to society we hope they are net benefits. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation),and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species.
Globally, biodiversity is in rapid decline the explosion of the human population from 2 to 7 billion in just 100 years has caused the extinction of many species. Because of this effect, human-caused biodiversity declines could result in decreased crop and timber production the dilution effect holds for parasites that are transmitted from animals to humans, not just those that circulate among wildlife species, the researchers found. We will try to answer the important question about what are the causes of biodiversity decline and we will analyse the effect of climate change on species diversity, ecosystems and the whole planet with a global perspective we will explore the implication for biodiversity of the gaia theory.
Deforestation is a direct cause of extinction and loss of biodiversity an estimated 18 million acres of forest are lost each year, due in part to logging and other human practices, destroying the. A sharp decline in biodiversity is affecting every region of the world, threatening the ability of citizens in many nations to find adequate food and clean water, according to a united nations report. Humans causing decline in biodiversity essay - as far as we can say, intelligent, modern humans have been around for roughly 50,000 years, and in that time have altered the earth beyond recognition (morrison, 2006.
Humans causing decline in biodiversity essays 2274 words 10 pages as far as we can say, intelligent, modern humans have been around for roughly 50,000 years, and in that time have altered the earth beyond recognition (morrison, 2006. Biodiversity loss, ecosystem degradation, and consequent changes in ecosystem services have also led to a decline in human well being in some groups by exacerbating poverty and increasing inequities and disparities (ma 2005b. Humans human activity has greatly distorted the ecosystems in the environment which resulted to invasive species invasive species can threaten an ecosystem and the biodiversity of the organism that exist in the present environment when the invasive species increase rapidly in number.
From failures to combat global warming to pollution and the exploitation of natural resources, human activity is significantly contributing to a worldwide and dangerous decline in biodiversity, jeopardizing nature's ability to benefit to people's wellbeing, according to a major study published friday. Lpi suggests a biodiversity decline of 52% from 1970 to 2010 declines seen in freshwater, marine and terrestrial spp but most severe are in freshwater spp large differences between temperate areas (where overall increasing) and tropical areas (where considerable declines. There is no doubt that human civilization has had a negative impact on biodiversity, particularly since the industrial revolution overfishing and hunting, the destruction of habitats through agriculture and urban sprawl, the use of pesticides and herbicides, and the release of other toxic compounds.
Each cause is intensified by human population growth and by our increasing per capita consumption of resources ____________ is the single greatest cause of biodiversity decline today habitat loss. While the drivers of global biodiversity decline are many and complicatedâ€including habitat destruction, deforestation, overexploitation of species, climate change, and ocean acidificationâ€they are also underpinned by one simple fact: the human population continues to boom. An overall decline of biodiversity was reported, but there was also a success in increasing protected areas the forest cover increased by 2,5% over the past 25 years there are, however, doubts whether these efforts are sufficient to stop the overall decrease of biodiversity.
The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world's ecosystem, in fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and transferring species from one area [. The growth of human populations, consumption levels, and mobility is the root of most of the serious threats to biodiversity today while learning about the negative impacts of humans on biodiversity, please keep a few things in mind. The loss of biodiversity is increasing there is massive extinction from human activity for example, fish stocks are dwindling, forest loss is resulting in the loss of many species, land and other resources are being misused, leading to various long terms costs. Two decades ago, at the first earth summit, the vast majority of the world's nations declared that human actions were dismantling the earth's ecosystems, eliminating genes, species and biological traits at an alarming rate.
