A complete global balance is being maintained by biodiversity. Biologists recognize the human species is embedded in ecosystems and is dependent on them, just as every other species on the planet is dependent. Catharanthus roseus, the Madagascar periwinkle, has various medicinal properties. October 17, 2013. The potatoes grown in that region belong to seven species, while the number of varieties is probably in the thousands. The ability to create new crop varieties relies on the diversity of varieties available and the accessibility of wild forms related to the crop plant that can be bred with existing varieties. http://cnx.org/contents/185cbf87-c72e-48f5-b51e-f14f21b5eabd@9.44:1/Biology. The seed vault is located deep into the rock of an arctic island. Humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by bacteria and fungi. Assess the interactions of biodiversity with agricultural diversity. These same seed companies, however, have participated in the decline of the number of varieties available as they focus on selling fewer varieties in more areas of the world. Fishery extinctions rarely lead to complete extinction of the harvested species, but rather to a radical restructuring of the marine ecosystem in which an abundant species is so over-harvested that it becomes a minor player, ecologically. Environmental stewardship can contribute to secure livelihoods and improve the resilience of communities. Additionally, there are moral arguments for the maintenance of biodiversity. It may not be clear why biologists are concerned about biodiversity loss. In addition, the loss of an inexpensive protein source to populations that cannot afford to replace it will increase the cost of living and limit societies in other ways. In general, the fish taken from fisheries have shifted to smaller species as larger species are fished to extinction. The potato demonstrates a well-known example of the risks of low crop diversity. Loss of biodiversity will impact the number of pharmaceuticals available to humans. Medicinal uses of plants: Catharanthus roseus, the Madagascar periwinkle, has various medicinal properties. Each organism within an ecosystem serves important functions that help balance the Earth’s ecology. Why might an arctic climate be good for seed storage? The natural disaster prevention mechanisms in most ecosystems and other free services we all get from the surrounding environment are not easily replaceable or replicable, so maintaining biodiversity is important. He argues that human evolutionary history has adapted us to live in a natural environment and that built environments generate stressors that affect human health and well-being. In general, the fish taken from fisheries have shifted to smaller species as larger species are fished to extinction. Most plants produce secondary plant compounds, which are toxins used to protect the plant from insects and other animals that eat them, but some of which also work as medication. In addition, the loss of an inexpensive protein source to populations that cannot afford to replace it can increase the cost of living and limit societies in other ways. Resource depletion, low biological growth rates, and critically low biomass levels result from overfishing. Loss of diversity in pest enemies will inevitably make it more difficult and costly to grow food. For example, potatoes were domesticated beginning around 7,000 years ago in the central Andes of Peru and Bolivia. The term biodiversity was coined in 1985. Why biodiversity matters. Overview. Additionally, there are moral arguments for the maintenance of biodiversity. Conditions within the vault are maintained at ideal temperature and humidity for seed survival, but the deep underground location of the vault in the arctic means that failure of the vault’s systems will not compromise the climatic conditions inside the vault. Biodiversity is an essential part of the solution to climate change. Sustainable seafood is seafood from either fished or farmed sources that can maintain or increase production in the future without jeopardizing the ecosystems from which it was acquired. Biologists recognize the human species is embedded in ecosystems and is dependent on them, just as every other species on the planet is dependent. This means we value biodiversity both for what it provides to humans, and for the value it has in its own right. In recent years, animal venoms and poisons have excited intense research for their medicinal potential; at least five of these drugs have been FDA approved since 2007. Biodiversity is very important to the well-being of our planet and here’s why. The importance of biodiversity to human health. Another five drugs are undergoing clinical trials. The diversity is driven by the demands of the topography, the limited movement of people, and the demands created by crop rotation for different varieties that will do well in different fields and microclimates. The Importance of Biodiversity to Human Life. In addition to growing crops and raising animals for food, humans obtain food resources from wild populations, primarily fish populations. Provides food to all the living beings: If you come across food chain in the nature, you will notice all … But the accelerated extinction rate means the loss of tens of thousands of species within our lifetimes, and it is likely to have dramatic effects on human welfare through the collapse of ecosystems and in added costs to maintain food production, clean air and water, and human health.
