Meet other Global Citizens who care about the same issues you do. [18] More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described. Biodiversity has been critical to advances throughout the field of bionics. Although some polyculture farmers use the same techniques, they also employ integrated pest management strategies as well as more labor-intensive strategies, but generally less dependent on capital, biotechnology, and energy. About 25% of world fisheries are now overfished to the point where their current biomass is less than the level that maximizes their sustainable yield. Exotic species that have become pests can be identified taxonomically (e.g., with Digital Automated Identification SYstem (DAISY), using the barcode of life). A biodiversity hotspot is a region with a high level of endemic species that have experienced great habitat loss. [92]Differences in the strength of the second-order feedback due to different intensities of interspecific competition might explain the faster rediversification of ammonoids in comparison to bivalves after the end-Permian extinction. The biggest driver of biodiversity loss is land-use change, when countries convert natural landscapes into a space for human activities like agriculture, mining, and urban expansion. For example, farmers are beginning to adopt bee-friendly agricultural standards that rewild areas previously degraded by heavy industry, while others are developing cooperatives that prioritize ecosystem renewal. The unclassed forests cover 6.4 percent of the total forest area and they are marked by the following characteristics: In zoological parks or zoos, live animals are kept for public recreation, education and conservation purposes. [98], There have been many claims about biodiversity's effect on these ecosystem services, especially provisioning and regulating services.

Biodiversity took the biggest hit in Latin America, plummeting 83 percent. DNA based markers- microsatellites otherwise known as simple sequence repeats (SSR) were therefore used for the diversity studies of certain species and their wild relatives. It is this importance and urgency with which humanity needs to act to protect biodiversity that may lead to rich countries having to pay for its protection. Their replacement by cropland could precipitate a disaster that is global in scale. [133][134] A significant proportion of drugs are derived, directly or indirectly, from biological sources: at least 50% of the pharmaceutical compounds on the US market are derived from plants, animals and microorganisms, while about 80% of the world population depends on medicines from nature (used in either modern or traditional medical practice) for primary healthcare. 3. to biodiverse countries like Brazil to halt and reverse biodiversity decline. Colombia’s incredible bird, amphibian, and plant richness allow it to beat out Indonesia on … Wright, Richard T., and Bernard J. Nebel. The inverse relationship of size and population recurs higher on the evolutionary ladder—to a first approximation, all multicellular species on Earth are insects". Since the ocean is a shared space, countries have to better coordinate with one another about fishing zones, transportation routes, and pollution. Biodiversity is the variety and variability of life on Earth.Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion—a period during which the majority of multicellular phyla first appeared. Law regarding species is more recent. Zoos play a major role in creating awareness about the need to conserve nature. Monoculture was a contributing factor to several agricultural disasters, including the European wine industry collapse in the late 19th century and the US southern corn leaf blight epidemic of 1970. While rich countries may object to being asked to pay to protect biodiversity in biodiverse countries, it is in the planet’s best interest to protect these areas and ensure the continuous provision of ecosystem services. Its strongest ranks come among birds, mammals, reptiles, and plants. [268] Insect extinction rates are high—supporting the Holocene extinction hypothesis.[269][270]. A pangolin looks for food on private property in Johannesburg, South Africa in February 2019. It is as if the natural world is an enormous bank account of capital assets capable of paying life sustaining dividends indefinitely, but only if the capital is maintained. Genetic pollution leads to homogenization or replacement of local genomes as a result of either a numerical and/or fitness advantage of an introduced species. Thinking about this diversity we might note that many small vegetable farmers grow many different crops like potatoes and also carrots, peppers, lettuce, etc. [citation needed][121] Many people depend on these species for food, shelter and clothing. Professor David Macdonald at Oxford University, “without biodiversity, there is no future for humanity.”. [225][226][227], According to a 2020 study by the World Wildlife Fund, the global human population already exceeds planet's biocapacity – it would take the equivalent of 1.56 Earths of biocapacity to meet our current demands. Papahānaumokuākea is one of the world’s largest Marine Protected Areas. In Europe many parts of the economy that generate trillions of euros per year depend on nature. Overexploitation occurs when a resource is consumed at an unsustainable rate. [6] There are latitudinal gradients in species diversity. [38], The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity. Rules around water use have to be updated to reflect dwindling resources and the overall good of human society and the planet. [202][203][204][205][206], Genetic erosion and genetic pollution have the potential to destroy unique genotypes, threatening future access to food security. Biodiversity forms the foundation of human society — water, food, and air — and time is literally running out for its protection, the report warns. [citation needed] Plant and animal species confined to a specific geographical area are called endemic species. : Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Modern zoos offer veterinary facilities, provide opportunities for threatened species to breed in captivity and usually build environments that simulate the native habitats of the animals in their care. More than two-thirds of the global population will live in urban areas by 2050, according to the report. Papahānaumokuākea is one of the world’s largest Marine Protected Areas.Image: Andrew Gray/NOAA. Podcast: Can the planet support a clean energy transition? The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light. For example, the introduction of kudzu from Southeast Asia to Canada and the United States has threatened biodiversity in certain areas. [95] It has been argued that the present rate of extinction is sufficient to eliminate most species on the planet Earth within 100 years. [149] The economic activity of pollination alone represented between $2.1–14.6 billion in 2003.[150]. [26] Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity 300 million years ago,[88] whereas others consider the fossil record reasonably reflective of the diversification of life. [126], The growing demand and lack of drinkable water on the planet presents an additional challenge to the future of human health. Bringing Indigenous communities into the process of land restoration through the creation of Indigenous and community conserved areas (ICCAs) is key to this process. The last extinction event took place 66 million years ago in which 76% of species, including the dinosaurs, were wiped out by an asteroid. [72] The latitudinal distribution of parasites does not appear to follow this rule. Increasing atmospheric carbon dioxide certainly affects plant morphology[211] and is acidifying oceans,[212] and temperature affects species ranges,[213][214][215] phenology,[216] and weather,[217] but, mercifully, the major impacts that have been predicted are still potential futures. [207][208] For example, coral reefs – which are biodiversity hotspots – will be lost within the century if global warming continues at the current rate.[209][210]. Due to its diversity of freshwater and marine ecosystems, the United States ranks particularly high in terms of fish species, while Venezuela is one of the world’s most biodiverse countries when it comes to birds. Vegetable farmer watering plants at the organic farm in Boung Phao Village, Laos.Image: Asian Development Bank. The scale-crested pygmy tyrant lives in Central America and northern South America. M. |Kunz T. H. |& Chilson |P. Countries have to take an active role in transforming the food system by first breaking the dominance of major food corporations that flood the world with cheap, processed foods. "[222][223] At least until the middle of the 21st century, worldwide losses of pristine biodiverse land will probably depend much on the worldwide human birth rate. Example: Gascon, C., Collins, J. P., Moore, R. D., Church, D. R., McKay, J. E. and Mendelson, J. R. III (eds) (2007). Until approximately 2.5 billion years ago, all life consisted of microorganisms – archaea, bacteria, and single-celled protozoans and protists. Sovereignty principles can rely upon what is better known as Access and Benefit Sharing Agreements (ABAs). Preventing this scenario demands that countries reimagine their relationship to bodies of water. Located in a tropical climate, Venezuela holds one of the 17 positions of megadiverse countries. The relationship between law and ecosystems is very ancient and has consequences for biodiversity. In the years ahead, countries have to retire forms of industrial agriculture and invest in forms of food production that allow ecosystems to flourish, according to the report. [267] For example, microbial life is metabolically and environmentally more diverse than multicellular life (see e.g., extremophile). Our best stories direct to your inbox every fortnight. This list focused on total biodiversity. Agriculture — the cultivation of plants and animals — is the leading driver of deforestation worldwide.
