Biodiversity change is caused by a range of drivers.A driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. Biodiversity is the variety of life on Earth at all its levels, from genes to ecosystems. Climate change–reflected in significant environmental changes such as warming, sea level rise, shifts in salinity, oxygen and other ocean conditions–is expected to impact marine organisms and associated fisheries. Research of long term trends in the fossil record suggests that natural speed limits constrain how quickly biodiversity can rebound after waves of extinction. Changes in the composition of ecosystems have also been observed (e.g. Changes in biodiversity and ecosystem services due to climate change are not all negative, with some species either thriving or adapting. Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. What does the Global Assessment cover? For example, losing diverse insect species will decrease plant pollination. Pollution can be in the air, water or on land. Although many studies have found that declines in biodiversity and increasing urbanization are strongly correlated (5, 15), research has also shown that in some situations biodiversity actually peaks in suburban areas for certain groups such as insects (7), and plants (6). Protecting biodiversity. In the past, there have bee n five great events of extinction which have shaped the earth in its cataclysmic ways. Practice. ... to extinction and inten-sifying climate change. How Does Pollution Affect Marine Life? By Michael Slezak. Humans are part of this web and our reliance on the other species is strong. Palaeontologists recognize five major extinction events from the fossil record, with the most recent, the Cretaceous mass extinction, ending some … The Holocene extinction is mainly caused by human activities. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The growth of human populations, consumption levels, and mobility is the root of most of the serious threats to biodiversity today. The Global Assessment also outlines the forces that affect biodiversity and ecosystems, forecasts what the future holds if trends continue or change, and explains what this all means for people and policy over the next three decades. Follow Us: Pollution affects animals by destroying their habitats, poisoning them, forcing them to migrate and causing disease or vulnerability. Biodiversity in the wild protects our food supply. Biodiversity loss. Hence, the rapid extinction rates mean that it could take a long time for nature to recover. #4 Lachanodes Arborea. Follow Us: Technology negatively affects the environment by compromising human health and safety, endangering natural ecosystems and biodiversity, having a cumulative impact on global systems, and depleting natural resources. Why? Why does biodiversity matter? The extinction of animals effects humans in lots of different ways. Biodiversity is not distributed evenly on Earth, and is richer in the tropics. The rapid loss of species we are seeing today is estimated by experts to be between 1,000 and 10,000 times higher than the natural extinction rate. *; These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. Additionally, this may decrease humanity's ability to produce medicine, as extinction claims more and more key plant species. Ian R. Swingland, in Encyclopedia of Biodiversity (Second Edition), 2013 Loss of Biodiversity and Causes. Biodiversity Defined and Why It Is Important.

This study provides an assessment of the potential impacts on, and the vulnerability of, marine biodiversity and fisheries catches in the Arabian Gulf under climate change. food or living space). How does climate change affect biodiversity? Also from the island St. Helena, this was a small tree otherwise known as the She Cabbage. It is estimated that the current rate of species extinction is between 1,000 and 100,000 times more rapid than the average rate during the last several billion years. Thesis: Humans affect biodiversity on many levels and it is important to realize these effects on an individual, societal, and government level and attempt to minimize them in order to ensure a future for humanity.

Once a species becomes extinct, it is gone forever. This means that we should view climate change as being part of the human society system. Two billion ... How does it affect our health? Disruptions in the food chain may greatly affect not only ecosystems but also humanity's ability to feed an ever-growing population. This does not mean creating merchandise for fundraising or sending XR a percentage of your sales. Pollution can be devastating for marine life, which is often sensitive to changes in their environment. Besides pollination, honey bees are important to the world’s population and ecosystem as they provide food security, sustainable farming and income, and biodiversity. The extinction of Flabellidium spinosum, otherwise known as the Santa Cruz bryophyte, is owed to the fact that its forest habitat and its immediate vicinity has been logged and cultivated over the years [7]. Our work reveals dramatic rates of decline that may lead to the extinction of 40% of the world's insect species over the next few decades. How Does Technology Affect the Environment? Species extinction is a natural process that occurs without the intervention of humans since, over geological time, all species have a finite span of existence. Threats to biodiversity.
