Should something drastic happen to affect ...
How does biodiversity affect the 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.
How does overexploitation affect biodiversity?
Overexploitation is another threat to biodiversity, again a largely human threat. Overfishing and overharvesting either remove competition for other species causes a huge shift in the stability of species richness and diversity. By removing too many of one species of fish, fishers allow other species to take over, perhaps upsetting the delicate balance between producer and consumer. Alternatively, fishers remove too many fish of a wide range of species, not immediately upsetting the balance of fish species but causing a drop in population and lower reproduction rates that allows certain types of plankton or algae to take over. The latter can cover large areas of fresh or salt water and remove the oxygen, causing a dead zone where nothing except anaerobic bacteria can survive. In agriculture, the overharvesting of crops leads to a lack of nutrients in the soil, where farmers then add nitrogen-containing fertilizers to make up for this loss. Nitrogen contributes greatly to global warming and climate change. A vicious circle of action and effect which slowly reduces biodiversity on first a local and finally a global scale.
How does biodiversity help the environment?
From the ground up, or from the ocean floor up, biodiversity increases soil formation, nutrient storage, energy storage, recycling, and the breaking down of toxins and pollutants. Rich biodiversity will speed the recovery of the environment after a natural disaster.

Biodiversity Definition
As stated above, the term "biodiversity" can be applied in multiple ways. This is because biodiversity considers the diversity of an ecosystem at multiple levels. For instance, biodiversity considers:
Species Biodiversity
Species biodiversity is the most common type of biological diversity measurement taken. Species diversity considers the total number of species within a given area.
Genetic Biodiversity
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.

How can we protect the iconic wildlife we all love?
To protect the iconic wildlife we all love, we must rebuild the web of biodiversity that supports it. We do this by rethinking how we’re using natural resources, easing the pressure and allowing ecosystems to recover. In the process all life benefits: plants, insects, fish, birds, mammals, and even people.

What are the threats to biodiversity?
The biodiversity hotspots around the world are facing severe threats from several anthropogenic activities like deforestation, forest fires, climate change, and poaching. Large swathes of forests have also been cleared for the expansion of agriculture, exploitation of natural resources, construction of roads, railways, dams, and housing for the burgeoning human population. This loss of large forest areas results in the alteration of the natural landscape, habitat loss, and extreme fragmentation of wildlife habitats, eventually leading to the rapid decline in the number of endemic species harbored in the hotspot region. Some of the invasive floral and faunal species that have been introduced due to human activities in different habitats subsequently eliminate the native species, thereby harming the ecosystem. The effects of anthropogenic climate change, urban tourism, and other recreational activities also put tremendous pressure on these fragile ecosystems.
What is biodiversity hotspot?

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…
