Addressing food security is a top global priority as illustrated in Goal 2 of achieving "Zero Hunger" of the Sustainable Development Goals. In order for the Tropical Andes, and the people who live off of it, to survive, it is critical that we take action to protect this region. The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. It is the variety of life on Earth, in all its forms and all its interactions. These processes contribute to the stability of the Earth's ecosystems and contribute to higher quality air, water, and food. High NPP directly contributes to -diversity by supporting more species with minimum viable populations . Greater species diversity ensures natural sustainability for all life forms. It reflects the number, variety and variability of living organisms and how these change from one location to another and over time. Loss of habitatfor example, when humans convert meadows into parking . While often treated separately, biodiversity loss and climate change are related and mutually reinforcing problems. Ecosystems are impacted by air pollution, particularly sulphur and nitrogen emissions, and ground-level ozone as it affects their ability to function and grow. Biodiversity in simple words defined as all forms of life that exist on planet Earth. To get an idea of the range of ecosystem services that we use daily, think of how much energy and time it would cost to make Mars (or some other Earth-like planet) hospitable for human life, for example, in terms of atmosphere regulation, freshwater . Ecosystem function is important for supporting plant and animal communities and ensuring our long-term survival. Supporting services are necessary for all other ecosystem services to exist. Benefits of Biodiversity to Humans. Air pollution, ecosystems and biodiversity. Biodiversity or biological diversity is the variety and variability of life on Earth.Biodiversity is a measure of variation at the genetic (genetic variability), species (species diversity), and ecosystem (ecosystem diversity) level. Biodiversity is good for the economy. This is nearly 1,000 times the "natural" or "background" rate. Yet, removing any one species can upset an ecosystem's delicate equilibrium. Industrial agriculture places consistency and productivity over biodiversity, but preserving the immense variety of life on earth is vital to the health of our planet and helps us safeguard our own food supply. Biodiversity plays an important role in regulating the climate, thus making a key contribution to climate change mitigation and adaptation. The concept of the balance of nature is an old and attractive one for which there is much evidence. Biodiversity affects our food, medicine, and environmental well-being. Human needs - The diversity of life forms provides us with a wide array of options for satisfying our needs, including our need for gainful employment. Species are designed to survive and adapt to certain areas in which they live. Recovery from this "Great Dying" didn't even begin for 4 to 6 million years, during which only a small number of resilient species roamed the earth. These interactions often create negative feedback loops, keeping the ecosystem in approximately the same state. It provides us with an array of foods and materials, and it contributes to the economy. Increase ecosystem productivity; each species in an ecosystem has a specific nichea role to play. The jobs of a significant portion of the workforce depend directly on biological resources including agriculture, fishing, forestry, eco-tourism and outdoor recreation. If a species is genetically unique if, for instance, it's far out on a remote arm of the evolutionary tree, like the distinctive, peculiar platypus its biodiversity value is greater than that of a species clustered with many similar species because it preserves a unique part of the . These include primary production (i.e., photosynthesis and chemosynthesis) of new organic matter, cycling of nutrients necessary for life, and pollination. 74% C. 58.88% D. 99.9% E. 99.9%. According to the UN Environment Programme, the Earth is in the midst of a mass extinction of life. We believe this is possible for two main reasons: 1.
