Why is biodiversity so important? - Kim Preshoff. What is Biodiversity? | Mocomi Kids. Why Conserve Biodiversity? We are learning more every day about the answers to this question, which has moved closer to the forefront of our collective psyche as new environmental challenges emerge. Biodiversity is the incredible, dizzying variety of life that surrounds us, including all of the earth’s plants, animals, their habitats, and the natural processes that they are a part of. It has become clear that biodiversity is the cornerstone of our existence on Earth. It is also important to conserve biodiversity for the sake of our own curiosity and aesthetic appreciation. Colorado’s mountains are spectacular, but what would they be without our splendid variety of wildlife and wildflowers?
Colorado is full of biodiversity wonders, many of which are unique to our state. Medicines originating from wild species, including penicillin, aspirin, taxol, and quinine, have saved millions of lives and alleviated tremendous suffering. 40% of all prescriptions are for medicines that originated from plants and animals. Biodiversity. What is biodiversity and why is it important?
Understanding Biodiversity An Introduction of CK 12 Understanding Biodiversity ch v1 fpf s1. Biodiversity ( Video ) | Biology. Biodiversity ( Read ) | Biology. What is biodiversity? How many species exist? We don't really know for sure. But all those species together, from the smallest bacteria, the deadliest protist, the most bizarre fungi, the prettiest plant, and the biggest mammal, compile the diversity of life, or biodiversity. What Is Biodiversity? Biodiversity refers to the variety of life and its processes, including the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur. Scientists have identified about 1.9 million species alive today. They are divided into the six kingdoms of life shown in Figure below. Known species represent only a fraction of all species that exist on Earth. Cogs and Wheels “The first rule of intelligent tinkering is to save all the pieces.” What are the “cogs” and “wheels” of life?
A discussion of biodiversity is available at Summary Biodiversity refers to the number of species in an ecosystem or the biosphere as a whole. Importance of Biodiversity ( Read ) | Biology. Why is biodiversity important? Think about how many species exist. Most likely well over 5 million. Now think about how much information about those species we do not yet understand.
We do not know what we can learn from them. Why Is Biodiversity Important? Human beings benefit in many ways from biodiversity. Economic Benefits of Biodiversity The diversity of species provides humans with a wide range of economic benefits: Wild plants and animals maintain a valuable pool of genetic variation. From flowers to fish, biodiversity benefits humans in many ways. Ecosystem Services of Biodiversity Biodiversity generally increases the productivity and stability of ecosystems. Plants and algae maintain the atmosphere. Summary Biodiversity has direct economic benefits. Explore More Use this resource to answer the questions that follow. Why is biodiversity important ?

Why is preserving the rainforest important? Preserving the rainforest is important for many reasons.
But one reason conservation efforts have focused here is that the rainforest is home to more species of insects, amphibians, and birds than anywhere else on the planet. This wide diversity of life is called biodiversity. Importance of Biodiversity Biodiversity is a measurement of the amount of variation of the species in a given area. More specifically, biodiversity can be defined as the variety of life and its processes, including the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur. A place such as a coral reef has many different species of plants and animals. Extinction is a threat to biodiversity. Coral reefs are one of the biomes with the highest biodiversity on Earth. Economic Importance Economically, there are many direct benefits of biodiversity.
Biodiversity and Technology Ecological Importance Summary Explore More. What is Biodiversity? Biodiversity is the variety of life. It can be studied on many levels. At the highest level, you can look at all the different species on the entire Earth. On a much smaller scale, you can study biodiversity within a pond ecosystem or a neighborhood park. Identifying and understanding the relationships between all the life on Earth are some of the greatest challenges in science.
Most people recognize biodiversity by species. Biodiversity at a Glance Let’s look at the species biodiversity within a local pond. Think you’re done? Biodiversity is More than Just Species Species diversity is only one part of biodiversity. Genetic Biodiversity is the variation in genes that exists within a species.
Some Biodiversity Facts Researchers have estimated that there are between 3 - 30 million species on Earth, with a few studies predicting that there may be over 100 million species on Earth! There is more biodiversity within tropical ecosystems than temperate or boreal ecosystems. Homegrown Biodiversity. Biodiversity. Biodiversity – Key To Ecosystem Health. 22 February 2000 by Kate Melville It has long been known that a diversity of plants and animals can be a good indicator of a healthy ecosystem. But University of Washington research, to be published in the Feb. 17 edition of the journal Nature, suggests the health of the ecosystem is rooted in a complex codependency between plants and animals that produce organic matter and simple organisms that break it down.
Plants and algae - referred to as producers - acquire nutrients from inorganic sources supplied by fungi and bacteria - called decomposers. Decomposers in turn acquire the carbon they need from the producers. The number of species in each group appears to correlate with how well the ecosystem functions, with greater diversity bringing more efficiency, said Shahid Naeem, a UW assistant zoology professor and lead author of the study described in Nature.
"The effects of producer diversity on ecosystem function is only part of the picture," he said. Why Is Biodiversity Important? Who Cares? It was noted earlier that ecosystems provide many services to us, for free. Although some dislike the thought of trying to put an economic value on biodiversity (some things are just priceless), there have been attempts to do so in order for people to understand the magnitude of the issue: how important the environment is to humanity and what costs and benefits there can be in doing (or not doing) something. The Economics of Ecosystems and Biodiversity (TEEB) is an organization — backed by the UN and various European governments — attempting to compile, build and make a compelling economics case for the conservation of ecosystems and biodiversity. In a recent report, The Economics of Ecosystems and Biodiversity for National and International Policy Makers 2009, TEEB provided the following example of sectors dependent on genetic resources: In addition, it is estimated that implementing REDD (Reducing Emissions from Deforestation and Forest Degradation) could help.
Large-scale biodiversity is vital to maintain ecosystem health. Over the years ecologists have shown how biological diversity benefits the health of small, natural communities. New analysis by ecologists at UC Santa Cruz demonstrates that even higher levels of biological diversity are necessary to maintain ecosystem health in larger landscapes over long periods of time. Think of it as patches on a quilt, says Erika Zavaleta, UCSC associate professor of environmental studies.
Each patch may be a diverse habitat of plants, animals, and insects but it is equally important that the landscape “quilt” is made up of a diversity of patches that are different from each other. "A mix of meadows, young forest, old forest and shrub lands, for example, might provide more benefits than a landscape of continuous young forest, even if that young forest itself has high biodiversity," Zavaleta said.
Lead author Jae R. Tilman – also a co-author – created 168 plots nine meters square and planted them with randomized combinations of perennial grassland species. Bioindicators.
