Pollution. Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study from an international research team. Biodiversity is threatened by a variety of global changes resulting from the combined actions of human society. But we can never get back the species we have lost. Note that these pressures are also because of human activity. Human Population Growth: The Effects on Biodiversity 3 Replies "The massive growth in the human population through the 20th century has had more impact on biodiversity than any other single factor." -Sir David King, science advisor to the UK government. Over 75 percent of earth's habitable land has been degraded. At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease-carrying species. to realize the impact we have on biodiversity because without it, there would be no human existence. Biodiversity is the basis of the multiple benefits provided by ecosystems to humans. Despite the increase of the total impact, the biodiversity loss per unit of electricity generation reduced from 3.2 × 10−5 to 2.5 × 10−5 PDF m3 year/kWh . Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict. This article discusses the global problem of biodiversity loss, its causes and why biodiversity is important for human society. Humans use at least 40,000 species of plants and animals a day. The intensifying emergence of infectious pathogens has many underlying reasons, all driven by the growing anthropogenic impact on nature. Protecting the global commons from widespread destructive human activities is critical to mitigate climate change, to ensure the persistence of the world's terrestrial ecosystems, to stop the loss of biodiversity, and to protect nonhuman primates from the catastrophic consequences of climate change, habitat loss, and population decline caused by unsustainable human activities. The effects of drivers such as climate change, land and sea use change, overexploitation of resources,. Biodiversity, or biological diversity, is a term that refers to the number of genes, species, individual organisms within a given species, and biological communities within a defined geographic area, ranging from the smallest ecosystem to . Causes . Biodiversity in the broad sense is the number, abundance, composition, spatial distribution, and interactions of genotypes, populations, species, functional types and traits, and landscape units in a given system ().Biodiversity influences ecosystem services, that is, the benefits provided by ecosystems to humans, that contribute to making human . — Mr. Cook's sanity. Pollution as a result of human activity is a well known negative impact on biodiversity and animal populations. Air and land pollution can affect animal species' habitats and environments, making it difficult for them to survive, or else impact food supplies and reproductive performance, causing those species to slowly become extinct. Climate Change. Very worrying indeed. First, it increases the number of disease-carrying animals in local populations. Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before. Consensus statement one There is now unequivocal evidence that biodiversity loss reduces the efficiency by which ecological communities capture biologically essen- tial resources, produce biomass, decompose and recycle biologically essential nutrients. Biodiversity, the diversity of life on Earth, is essential to the healthy functioning of ecosystems. Close Section Given the adverse effects of fossil fuel extraction on species' habitats, this is a really significant step. 2.1 Biodiversity loss has negative effects on several aspects of human well-being, such as food security, vulnerability to natural disasters, energy security, and access to clean water and raw materials.

For humans that is worrying. Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. The most direct threats are overharvesting and loss/disturbance of habitat resulting from conversion of natural ecosystems to human use (thick red arrow). A reduction in biodiversity can also affect the number of fish and wild animals that can be harvested. Biodiversity is the amount of variance of life in a certain area and depending on the amount of biodiversity in each ecosystem it can weaken or stabilize the surrounding area. The loss of biodiversity and ecosystem loss or the mass extinction happening currently at 100 to 1000 more rate than the natural manner is due to human activities. With biodiversity loss, a huge impact on human health comes as well. Biodiversity loss and the ecological crisis have become hot topics in recent years but why does the loss of biological diversity matter to humans and what problems could we be facing as this crisis escalates? The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species. Over 75 percent of earth's habitable land has been degraded.

The loss of biodiversity has two significant impacts on human health and the spread of disease. Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate. The impact of biodiversity on any single ecosystem process is nonlinear and saturating, such that change accelerates as biodiversity loss increases. The decline in biodiversity and climate change will have a compounded effect on human health. The first two of these are a direct result of human population growth and resource use. We are all vulnerable to the myriad of effects that a loss in biodiversity has on our health. If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Effects of Human Activities on Environment are as Follows. biodiversity loss - biodiversity loss - Ecological effects: The weight of biodiversity loss is most pronounced on species whose populations are decreasing. (secondary to HS-LS2-7) • Humans depend on the living world for the resources and other benefits provided by biodiversity. There is massive extinction from human activity. Since living organisms interact in dynamic ecosystems, the disappearance of just one species can have a far-reaching impact on the food chain. Human societies have been built on biodiversity. Balance of payments reverts to short fall in Jan. By Ludwig O. Federigan.
