What are the benefits of biodiversity?
The four key benefits are: (1) Biodiversity Provides the Natural Resource, (2) Biodiversity Provides the Genetic Resource, (3) Biodiversity Maintains a Stable Ecosystem, and (4) Biodiversity Ensures Optimum Utilization and Conservation of Abiotic Resources in an Ecosystem.
Which region has the richest biodiversity?
Tropical regions are having the richest biodiversity in the world, most of the nutrients are lodged in its biotic community. Due to warm and humid conditions decomposition of organic matter and regeneration of nutrients take place rapidly.
What are microbes good for?
Microbes are also good sources of various medicinally important enzymes ( streptokinase and asparginase), toxins (botulin), immunomodulators (Cyclosporin A) etc. Vaccines such as BCG, typhoid, hepatitis B, and alkaloids such as ergot are also derived from some microbes.
Why are plants important to humans?
The most important contribution of plants is to provide food to ever increasing human population.
How does vegetation affect soil?
Luxuriant growth of vegetation hinders rapid flow of water, binds soil particles together and prevents soil erosion. Loss of biodiversity reduces the efficiency of this vital machinery which in turn results in rapid losses of nutrients and degradation of soil.
How does biodiversity contribute to agriculture?
In this way, biodiversity contributes to agriculture both by increasing productivity and protecting yield. The environment also provides medicines, both of the traditional and modern variety. Humans harvest an estimated 50-70,000 plant species worldwide ("How does," 2011).
How is biodiversity correlated with ecosystem productivity?
Biodiversity is positively correlated with ecosystem productivity by a mechanism known as functional complementarity, which states that the more species there are, the more nichesare occupied , and thus the greater productivit y of the eco system (Wilby & Hector, 2008).
What percentage of the world's economy is derived from biological resources?
The United Nations Convention on Biological Diversity, notes that, "at least 40 per cent of the world's economy and 80 per cent of the needs of the poor are derived from biological resources" ("Convention", 2011). Saving this biodiversity is in the self-interest of the human race. Commercial Benefits.
How does the natural environment affect climate?
The natural environment can also protect from winds, prevent soil and coastal erosion, and moderate temperatures. The oceans, for instance, play a major role in temperature and climate regulation due to the great heat capacity of water.
What are some examples of biodiversity-dependent research?
Examples of biodiversity-dependent research include bioengineering organs from tissues that can be transplanted in a patient's body, searching for new medicines to cure cancer, and improving human nutrition. The possibilities are nearly endless.
Why do pests survive?
Pests have the ability to survive pesticides because non-resistant organisms are naturally selected against. Beacuse of this, new pesticides and herbicides must constantly be created. More and more pests are becoming resistant to pesticides at an increasing rate, faster than controls can be developed (Bellinger 1996).
Why are commercial benefits important?
Commercial Benefits. All organisms need food to survive. Although humans consume only a small number of species, these species depend on many, many others in order to thrive. Additionally, the agricultural processes of intercropping and crop rotations have been used for thousands of years to increase productivity.
Why is biodiversity important to humans?
Why is biodiversity important to people? Humans depend on functions performed by the world’s ecosystems. Ecosystems produce oxygen, purify and detoxify the air and water, store and cycle fresh water, regulate the climate, form topsoil, prevent erosion and flood damage, and produce raw materials, foods and medicines.
How have ecosystems been treated?
Ecosystems have been treated like machines that will supply our needs as long as some basic conditions are optimized. For example, species deemed to be undesirable are removed and replaced by commercially valuable species that are “harvested” at constant rates.
Why is the ecosystem more resilient?
In ecosystems that have many species that can fulfill a given function, the ecosystem is more resilient. In other words, it is able to respond to disturbances such as disease or fire without collapsing. This apparent redundancy is a very effective insurance, for if one species succumbs to a disease, its “function” in the ecosystem is taken ...
What happens if one species succumbs to a disease?
This apparent redundancy is a very effective insurance, for if one species succumbs to a disease, its “function” in the ecosystem is taken over by another species . Ecosystems with limited diversity, including monocultures (areas entirely dominated by a single species, as in most agricultural crops), are much more prone to disease ...
How much of the world's food crops depend on pollination?
Protecting and remediating these natural systems cost much less. Over 75% of staple food crops and 90% of flowering plants worldwide depend on pollination by insects and other animals. Between 100,000 and 200,000 species of animals act as pollinators, and their populations are declining.
How much is ecosystem service?
The value of the world’s ecosystem services has been (conservatively) estimated at $33 trillion per year. The state of New York discovered that wetlands and other natural systems in the watershed accomplished water purification and filtration that would require an $8 billion water treatment plant to replace.
What is an ecosystem?
Ecosystems are composed of complex relationships between organisms and their physical environment. These relationships are constantly fluctuating, and are rarely predictable. This relatively simple concept has eluded western scientists until quite recently. Ecosystems have been treated like machines that will supply our needs ...
Why is biodiversity important?

How does biodiversity help our economy?
1. Biodiversity ensures health and food security. Biodiversity underpins global nutrition and food security.
How much do humans get from ecosystems?
Humans derive approximately $125 trillion of value from natural ecosystems each year. Globally, three out of four jobs are dependent on water while the agricultural sector employs over 60% of the world’s working poor. In the Global South, forests are the source of livelihoods for over 1.6 billion people.
What is biodiverse ecosystem?
Biodiverse ecosystems provide nature-based solutions that buffer us from natural disasters such as floods and storms, filter our water and regenerate our soils. The clearance of over 35% of the world’s mangroves for human activities has increasingly put people and their homes at risk from floods and sea-level rise.
What is the restoration economy?
Although some fear environmental regulation and the safeguarding of nature could threaten businesses, the “restoration economy” – the restoration of natural landscapes –provides more jobs in the United States than most of the extractives sector , with the potential to create even more.
Why are coral reefs important?
Coral reefs are essential to tourism in some parts of the world – but they're disappearing. Image: REUTERS/David Gray/File photo. There is great potential for the economy to grow and become more resilient by ensuring biodiversity. Every dollar spent on nature restoration leads to at least $9 of economic benefits.
What are some indigenous foods that have adapted to local conditions?
Every country has indigenous produce – such as wild greens and grains – which have adapted to local conditions, making them more resilient to pests and extreme weather. In the past, this produce provided much-needed micronutrients for local populations.
