What is the most beautiful thing about biodiversity?
But one of the most beautiful things about biodiversity is its resilience. Ease up on the pressure, manage resources well, give it time, and the ecosystem will adapt. Nature and biodiversity will recover. That’s exactly what WWF is working to do in Borneo.
How has the ocean environment changed?
Three-quarters of the land-based environment and roughly 66% of the ocean environment have been significantly altered. More than a third of the world's land surface and nearly 75% of freshwater resources are now devoted to crop or livestock production. Climate change worsens the impact of other stressors on nature and our wellbeing. Humans have overfished the oceans, cleared forests, polluted our water sources, and created a climate crisis. These actions are impacting biodiversity around the world, from the most remote locales to our own backyards.

What is biodiversity?from study.com
Biodiversity is the measurement of variation within living systems. It is typically divided into three categories:
Why is Biodiversity Important?from biologydictionary.net
Every single species has a role to play, although some – like viruses and disease-carrying mosquitoes – are considered to be damaging to the well-being of humans and other organisms and steps are being taken to eradicate them.
Why is it important to have niches in an ecosystem?from study.com
In ecosystems with high diversity, niches are full and have overlapping species. This means that there may be a large variety of predators and prey. While this competition may seem counterintuitive, this is beneficial for the ecosystem. If one species fails (becomes overharvested, for example) other species of similar roles can step in and prevent the ecosystem from completely collapsing.
How does biodiversity affect the stability of an ecosystem?from study.com
So, how does biodiversity affect the stability of an ecosystem? Biodiversity is closely related to ecosystem stability. Each ecosystem will have several niches for individual species to fill. In ecosystems with few species, niches may only have one or two species or lack any species at all. This can result in extreme ecosystem vulnerability.
How does deforestation affect biodiversity?from biologydictionary.net
Biodiversity also has a role to play in the stability of the ecosystem and global climate. Deforestation removes trees responsible for the conversion of carbon dioxide into oxygen. This increase in carbon dioxide levels in the air is partially (but significantly) responsible for global warming. Deforestation also leads to soil erosion where other species of plant suffer, with the forming of desert-like areas as a result. The domino effect of this means less food for herbivores (primary consumers) and a consequent reduction in populations due to competition. And with fewer herbivores, one can expect reduced populations of omnivores and carnivores. As every organism has a role to play in its ecosystem, the act of deforestation without (at minimum) replanting lost mature trees, can be catastrophic both locally and globally.
What is ecological biodiversity?from study.com
Ecological biodiversity (also called ecosystem biodiversity) is a type of biodiversity that considers the number of different ecosystems. Ecological biodiversity is often concerned with large scales. For instance, researchers may want to know the number of ecosystem types within a continent, or perhaps even across the globe. As certain ecosystem types are lost due to desertification, measuring ecological diversity has become increasingly important.
How is biodiversity measured?from biologydictionary.net
Ecological biodiversity is measured by looking at its three levels of genetic, species and ecosystem diversity.
What is biodiversity used for?
As stated above, biodiversity can be used to provide a measurement of diversity at multiple different levels. Three commonly measured types of biodiversity include:
How is biodiversity measured?
Ecological biodiversity can be measured at small scales. Microclimates are small, separate ecosystems with a larger ecosystem that experience varying conditions. For instance, within a forest, there may be a cool, damp ecosystem under a log that has vastly different conditions than a dry, hot rocky surface a few feet away. To understand niches, which are ecological roles organisms fill, understanding microclimates and ecological diversity at small scales is required and can give insight into species diversity.
Why is it important to have niches in an ecosystem?
In ecosystems with high diversity, niches are full and have overlapping species. This means that there may be a large variety of predators and prey. While this competition may seem counterintuitive, this is beneficial for the ecosystem. If one species fails (becomes overharvested, for example) other species of similar roles can step in and prevent the ecosystem from completely collapsing.

In ecosystems with few species, niches may only have one or two species or lack any species at all. This can result in extreme ecosystem vulnerability.
What is genetic diversity?
Genetic biodiversity considers the diversity of genomes within an ecosystem. Genetic biodiversity, like species diversity, can come in many forms and be measured at different scales. For instance, on a small scale, researchers may be interested in the diversity of nucleotides between individuals of a single population and species. Information obtained at this level is excellent for helping conservationists determine a species' health and outlook. Species with low genetic diversity between individuals may be subject to inbreeding. Because there is little variation between members of the population, the population is more susceptible to detrimental genetic mutation or susceptibility to disease. Thus, populations with low genetic diversity are more likely to crash than those with high genetic diversity. Low genetic diversity is usually the result of a small population.
What is the difference between alpha and beta diversity?
Species diversity is often considered in terms of alpha, beta, and gamma biodiversity. Alpha diversity is the total number of species within a defined area. Beta diversity compares two ecosystems and provides the number of species that do not overlap between ecosystems. Gamma diversity considers the total number of species across all given ecosystems. Explore the figure below to better understand how these three terms are used.
What depends on the type of diversity measured and the scale at which it is applied?
Thus, biodiversity depends on the type of diversity measured and the scale at which it is applied.

What does biodiversity do to the ecosystem?
Biodiversity allows for ecosystems to adjust to disturbances like fires and floods.
How to understand genetic diversity?
A helpful way to understand genetic diversity is to think about dogs. All dogs are part of the same species, but their genes can dictate whether they are Chihuahua or a Great Dane. There can be a lot of variation in genes—just think about all the colors, sizes, and shapes that make up the genetic diversity of dogs.

Why should we educate people about biodiversity?from embibe.com
Education: People should be educated about the importance of the ecosystem and the preservation of biodiversity. They should also know the consequences of declining biodiversity so people can seriously take part in the growth of healthy biodiversity.
What are the consequences of biodiversity loss?from embibe.com
The Consequences of loss of biodiversity are: 1 Food Production: Biodiversity loss impacts food production by decreasing the nutrient level of the food and the growth of food crops. 2 Spread of Disease: The loss of biodiversity causes degradation of the ecosystem, which leads to exposure to disease in animals, plants, and human beings. 3 Loss of Habitat: The biodiversity loss may cause loss of habitat for many species that may lead to the extinction of many species. In addition, deforestation may cause the destruction and displacement of many species. 4 Natural Disaster: The loss in biodiversity can form an unsustainable ecosystem which can lead to natural disaster like floods, droughts, forest fire, earthquake. 5 Pollution: The declining biodiversity can increase the pollution level, which may lead to an unhealthy environment. 6 Soil Erosion: The intensive usage of soil for agriculture may lead to soil erosion. 7 Economic Effects: We get many substances from a healthy environment that have economic value, but due to loss of biodiversity, the ecosystem fails to provide the valuable natural elements.
Why is biodiversity lost?from embibe.com
Deforestation: Deforestation is one of the reasons for biodiversity loss because the tree is home to many animal species, and when the trees are cut, many species lose their habitat. Over Exploitation of Natural Resources: Overusing the natural resources available in the ecosystem forces loss of biodiversity.
What happens when a species is eliminated from the ecosystem?from britannica.com
Even though a species is not eliminated from the ecosystem or from the biosphere, its niche(the role the species play in the ecosystems it inhabits) diminishes as its numbers fall. If the nichesfilled by a single species or a group of species are critical to the proper functioning of the ecosystem, a sudden decline in numbers may produce significant changes in the ecosystem’s structure. For example, clearingtreesfrom a foresteliminates the shading, temperatureand moisture regulation, animal habitat, and nutrienttransport services they provide to the ecosystem.

Threats to Biodiversity
- The greatest threat leading to the loss of biodiversity is the human race. As our populationgrows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural ones. Even in these, other organisms can adapt and successfully reproduce, but the levels of biodiversity as compared to the replaced env…
Benefits of Biodiversity
- Species can have instrumental or intrinsic (inherent) value. When of use to humans, either as a pleasing aspect (a pet dog) or a useful one (willow bark as a pain killer), they are instrumental. If a species has other value beyond its use to the human race, it has intrinsic value. This would include the fact that a species is part of the world’s natural history. New discussions regarding t…
