THREATS TO BIODIVERSITY

THREATS TO BIODIVERSITY
The biggest reason for the current increase in extinctions is habitat loss. Destruction of tropical forests, coral reefs, estuaries. Marshes, and other biologically rich ecosystems threaten to eliminate thousands or even millions of species in a human-caused mass extinction that could rival those of geologic history.
DRIVERS OF CHANGE
A driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem which results change in biodiversity.
These are two types of drivers:
• Direct drivers
• Indirect drivers
Main Causes of Threat to Species
It is well known now that several plant species have become extinct due to certain natural phenomena, such as land disturbances, volcanic eruptions, glaciations, protracted periods of rain or drought, spreading of desert lands, forest fires and eutrophication in the geological past. While such natural processes in the past had no doubt led to the extinction of flora, the resulting new environmental conditions had also resulted in the evolution and speciation of new flora and migration of floral elements. But, in recent times man with his anthropogenic associates and other factors or practices such as fire or ‘slash and burn’ for shifting cultivation (also called as ‘jhum’ or ‘podu’cultivation in India), grazing by cattle and by several other mechanical means, has suddenly accelerated disastrous condition in natural ecosystems. Besides, commercial exploitation of entire plants, roots, rhizomes, tubers bulbs seeds and fruits has been the prime cause of depletion of more important wild economic plants throughout the world for lucrative financial gains, in the trade which flourishes both by legal and illegal means Rauvolfia serpentina, Coptis teeta, Dioscorea sp. and Podophylum hexandrum serve as good examples.
(Habitat loss
Habitat loss:- Habitat loss can be described when an animal loses their home. Every animal in the animal kingdom has a niche, a their in their animal community and without their habitat they no longer have a niche. Reasons of habitat loss by humans: ~ agriculture, farming ~ harvesting natural resources for personal use ~ for industrial and urbanization development Habitat destruction is currently ranked as the primary causes of species extinction world wide…!!!

Hunting and Poaching
Poaching: - Poaching is the hunting and harvesting taking of wild plants or animals, such as through hunting, harvesting, fishing, or trapping.
Uncontrolled hunting of wildlife for pleasure, food, furs. Skins, horns, tusks, etc. pose a serious threat to the survival of wildlife. In India, the Cheetah was hunted to extinction. The illegal trade in animal skins has been responsible for the destruction of a large number of tigers, leopards, deer, fishing cat, crocodiles and snakes, as well as birds with beautiful plumage. Elephants were hunted for ivory.
Man and Wildlife Conflict
Man–wildlife conflict refers to the interaction between wild animals and humans, and the resultant negative impact on people, animals, resources, and habitats. It occurs when growing human populations overlap with established wildlife territory, creating competition for space and resources.
Introduction of Invasive Species
An exotic or unnatural species can be any kind of organism that has been introduced to a foreign habitat. This introduction can cause major threats to the native species as they often become subjected to great competition for resources, disease, and predation. When these species have successfully colonized the area, they are already called “invasive” ones.
Overexploitation refers to the act of overharvesting species and natural resources at rates faster than they can actually sustain themselves in the wild. Because of this, species population is put into great risk of reduction
.Climate change
Climate change refers to the long term and irreversible change that occurs in the Earth’s climate. This increase in the temperature of the atmosphere has major effects on the environment such as the seasons, rising of the sea levels, and glacial retreats
OTHER potentail threats, diseases like ebola flue and COVID-19

The threats to Biodiversity #biodiversity #climatechange #pollution

The threats of some human activities on Biodiversity. What do you know about biodiversity?
Biodiversity is a variety of life and variability of life on earth. There are 8.7 millions species on planet earth. Human activities are reducing biodiversity and our future depends upon maintaining a good level of biodiversity. The following are some of the human induced threats facing biodiversity: degradation, deforestation, habitat fragmentation, alien species, pollution, climate change and etc. We cannot address biodiversity loss without tackling climate change, because the impacts of climate change on man are largely mediated the natural systems.

Plant Poaching the new biodiversity threat. (Episode 23)

Plant poaching or the or the illegal plant trade is the newest threat to our ecosystems and biodiversity. Taking plant en masse harms the creatures that need them to survive and also other plants with symbiotic relationships to them. With the pandemic having created loss of jobs for many in the Philippines many people have resorted to poaching wild plants to fulfill the new hobby of those stuck at home. It is not only illegal it does so much damage to the ecosystems.
