The Importance of Biodiversity for Development

Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level. Rapid environmental changes typically cause mass extinctions. The age of the Earth is about 4. There are microbial mat fossils found in 3. Since life began on Earth , five major mass extinctions and several minor events have led to large and sudden drops in biodiversity.

Biodiversity is the foundation of ecosystem services to which human well-being is intimately linked. No feature of Earth is more complex, dynamic, and varied than the layer of living organisms that occupy its surfaces and its seas, and no feature is experiencing more dramatic change at the hands of humans than this extraordinary, singularly unique feature of Earth. This layer of living organisms—the biosphere—through the collective metabolic activities of its innumerable plants, animals, and microbes physically and chemically unites the atmosphere, geosphere, and hydrosphere into one environmental system within which millions of species , including humans, have thrived. It follows that large-scale human influences over this biota have tremendous impacts on human well-being. It also follows that the nature of these impacts, good or bad, is within the power of humans to influence CF2.

Existence of huge diversity of life forms is key feature of the blue planet. All the life forms ranging from bacteria to plants or animals play important roles on the only celestial body known to harbor life in the universe. These life forms are in dynamic relationship with one another. It is impossible for any life form to survive on earth without the direct or indirect support of other organisms. Biodiversity is thus a key feature of the planet earth and important for sustaining the ecosystems on it. Biodiversity is also exploited for various purposes by humans and helps in improving the quality of our lives. In fact the existence of human civilization is directly linked to the biodiversity of the planet.

Biodiversity is the sum of all the different species of animals, plants, fungi and microbial organisms living on Earth and the variety of habitats in which they live. Scientists estimate that more than 10 million different species inhabit Earth. Biodiversity underlies everything from food production to medical research. Humans use at least 40, species of plants and animals on a daily basis. Many people around the world still depend on wild species for some or all of their food, shelter and clothing.

Biodiversity or Biological diversity is a term that describes the variety of living beings on earth. In short, it is described as a degree of variation of life. Biodiversity also refers to the number or abundance of different species living within a particular region. It represents the wealth of biological resources available to us. If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us. In biodiversity, each species, no matter how big or small, has an important role to play in the ecosystem.

Biodiversity: Types, Importance and Conservation Methods (with diagram)

Biodiversity conservation, the practice of protecting and preserving the wealth and variety of species, habitats, ecosystems, and genetic diversity on the planet, is important for our health, wealth, food, fuel, and services we depend on. It plays an integral role in supporting many sectors of development. Recognizing that improving livelihoods, security, and human health depends on the conservation of biodiversity in healthy ecosystems, USAID leads the U. MACH works with communities to responsibly manage wetlands through improved conservation measures and sustainable fishing practices.

Our dependence upon biodiversity, however, goes far beyond simple consumption of resources. Biodiversity influences how disease occurs in an individual or population, how the local climate is able to support life, and how resilient an area will be against flooding or a catastrophic storm.

Целясь в торс, он сводил к минимуму возможность промаха в вертикальной и горизонтальной плоскостях. Эта тактика себя оправдала. Хотя в последнее мгновение Беккер увернулся, Халохот сумел все же его зацепить. Он понимал, что пуля лишь слегка оцарапала жертву, не причинив существенного ущерба, тем не менее она сделала свое .

Сьюзан плохо его понимала. Ей показалось, что столь своевременная кончина Танкадо решила все проблемы. - Коммандер, - сказала она, - если власти говорят, что он умер от сердечного приступа, это значит, мы к его смерти не причастны. Его партнер поймет, что АНБ не несет за нее ответственности. - Не несет ответственности? - Глаза Стратмора расширились от изумления.

    In addition, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change.
