Important facts: • the ocean covers 70% of earth • over 50% of humans live in the coastal zone and draw 90% of our marine-living resources from this region • life evolved in the ocean 27 billion years before terrestrial life. Biodiversity is the interconnectivity of nature that defines the existence of every living being on earth this interconnectivity is the life support system of all life on earth high connectivity results in high biodiversity. Earth's biodiversity -- the number of microorganisms, plants, and animals, their genes, and their ecosystems -- is declining at an alarming rate, even faster than the last mass extinction 65. It supplies life on earth with energy, harnessed from the sun the sun releases a lot of energy through constant nuclear reactions (the fusion of hydrogen) plants have the ability to use the light energy it releases to produce glucose which they can then store and use this stored glucose (stored as starch due to it being insoluble) is then consumed by the next organism in the food chain. Context - biodiversity contributes to many aspects of human well-being, for instance by providing raw materials and contributing to health the millennium ecosystem assessment shows that human actions often lead to irreversible losses in terms of diversity of life on earth and these losses have been more rapid in the past 50 years than ever before in human history.
Earth is home to 80,000 species of snails and slugs about 5,000 species of frogs have been recorded ten thousand species of birds decorate the skies our planet provides habitats for about 3,000. This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet earth in biology , evolution is any change across successive generations in the heritable characteristics of biological populations. Primary importance for the economic development hence conservation of biological resources are very important for the economic life of a nation biodiversity is a part of the biosphere supported by biological processes and.
The question 'why is biodiversity important' is undoubtedly one of the most intricate, but important questions to be asked as far as the existence of life on our planet is concerned taking this into consideration, we have compiled some of the most important questions about the importance of biodiversity. Biodiversity is the sum total of life on earth the entire global complement of terrestrial, marine, and freshwater biomes and ecosystems, and the species — plants, animals, fungi, and microorganisms — that live in them, including their behaviors, interactions, and ecological processes. Biodiversity comes from two different roots ‘bios’ is greek for ‘life’ ‘diversus’ means ‘different or various’ thus, biodiversity means a diversity of lifemore specifically, biodiversity refers to the fact that there are many different species in existence on the planet. Essay on the importance of biodiversity article shared by biodiversity, a contraction from biological diversity is a reference to the varied life forms on earth, plants, animals and micro-organisms, their varied genes pools and habitats in the desert, oceans, coral reefs, forests and elsewhere. Biodiversity or biological diversity is a term that describes the variety of living beings on earth in short, it is described as degree of variation of life biological diversity encompasses microorganism, plants, animals and ecosystems such as coral reefs, forests, rainforests, deserts etc.
There's a very important economic aspect to biodiversity as well in 1997, cornell university scientists tallied the dollar value of all the services provided for humanity by life on earth everything from ecotourism and pollination to soil formation and pharmaceuticals was taken into account. 42 discuss the importance of the maintenance of biodiversity the biodiversity found on earth today is the result of approximately 35 billion years of evolution until the emergence of humans, the earth supported more biodiversity than any other period in geological history. Biodiversity is important to humans for many reasons biodiversity is also considered by many to have intrinsic value—that is, each species has a value and a right to exist, whether or not it is known to have value to humans the biodiversity book by the commonwealth scientific and industrial research organisation (csiro morton & hill 2014) describes 5 core (and interacting) values that.
Biodiversity generally refers to the variety and variability of life on earth according to the united nations environment programme (unep), biodiversity typically measures variation at the genetic , species ,and ecosystem level [1. Biodiversity makes life livable on earth by playing an important role in offering ecological services the ecological services include air purification, replenishing and cleaning water systems, absorbing chemicals, stabilizing climate, recycling nutrients, and forming and protecting the soil. Biodiversity is the amount of variety of life on earth it is the number of different species of plants, animals, and microorganisms it includes organisms from earth’s vastly different ecosystems, including deserts, rainforests, coral reefs, grasslands, tundra, and polar ice caps.
Life on earth importantly, biodiversity does not exclusively refer to species richness it also encompasses diversity at a wider scale meaning that differences in the genetic makeup of populations is important endemism has a key role to play in this context because endemic human existence has not stopped global human population increase. Biodiversity is a term that is commonly used when referring to mother earth and all its inhabitants bio, in its simplest form, means life that’s why biology is usually defined as the study of living things diversity comes from the adjective ‘diverse’, meaning variety. Life on the brink from earth magazine, (kalmbach publishing company), april 97 edition, delivers a very interesting answer to why biodiversity is important (unfortunately they no longer publish this magazine so the article is no longer online. View full lesson: our planet’s diverse, thriving ecosystems may seem like permanent fixtures, but they’re actually.
But the way we use these superlatives and the richness that they try to represent tells us something important about the way in which we perceive and relate to biodiversity and natural systems. According a high school graduate(me), biodiversity is important depending on what you value if you believe that there is no inherent moral reason to value all life on earth, or even any life on earth this is just a value we project onto our green planet- then biodiversity does not matter. Biodiversity, short for biological diversity refers to the variety of life it is an approach that looks at the amount of life and the variety of life over an area that area can be as large as the earth itself or it can be in a very small ecosystem such as the life in and surrounding a patch of moss on a fallen tree trunk. The ocean is home to a vast community invisible to the naked eye and yet vital to life on earth: micro-organisms this treasure of underwater biodiversity forms the first link in the food chain and produces up to 50% of the oxygen we breathe.
