Biodiversity means different types of life. “Bio” means life and “Diversity”
means many different.
It means the diversity of species on Earth, the diversity of the ecosystem
inhabited by the organisms, and the diversity of the genes of the organism.

Scientist research there are 8.7 million species like Bees,
Trees, Flowers, Deer, and Dolphins and many more. That is the examples of

But, as the human population grows, more resources are needed
and more pollution is occurred. As a result, Species Richness will decrease. Because
No two things can occupy the same place at the same time because the planet
capacity is limited.

makes the International Day for Biological Diversity on every May.22.
Also, Ms. Irina Bokova, Director-General of UNESCO gave
a message on the occasion of the International Day for Biological Diversity 2017.
She said Biodiversity is a life. It is very needed as much as cultural
diversity for mankind, and we need it to create a stronger and resilient

The Intergovernmental Panel on Climate Change (IPCC) predicts
that 20-30% of species will be extinct if the global average temperature rise
exceeds 1.5-2.5 ° C, and 40% if the temperature exceeds 4 ° C. (Füssel, H. M. ,2009)


Major human mediated causes of biodiversity loss (McKee, J. 2004).

Land-use Changes cause habitat destruction and
conversion to human use,

Human are doing too much Resource Exploitation
like over hunting,
illegal capture and overfishing cause the decrease of the specific specie’s population
and become extinct.
The only the reason for getting the ivory, so many Africa elephant has
been killed.

Nitrogen fertilizers cause the dead zone.( Singh, B., & Sekhon, G. S. ,1979)
the use of fertilizer nitrogen for farming is seriously pollution of the
groundwater and it goes to the lake or ocean it helps algae grow so fast  and cover on the top of the water , the
organism under the water cannot captured enough sunlight so, hard to photosynthesis.

As a result, marine plant will die . marine herbivore and carnivore will die as

Human make mass of Chemical Pollution and waterborne
pollutants are dump to the river. Many kind of chemical compound which human
produce ocean like drugs, PCB are dumped into the. And it make Hormone mimics
act like hormone. It controls the normal wild natural development and effect to
reproduction organ of it. Noise pollution ; Birds in city react the noise
level. Bird adapted the urban environment and they change the behavior and
reproductive pattern. But some of them just can’t do it.

Air pollution is that Harmful substances in
the atmosphere Increase in the amount of particles and gas components (carbon
monoxide, nitrogen oxides, sulfur oxides, hydrocarbons, etc.)
(Manning, W. J.,
Air pollution damages plants and animals and causes of acid rain, so the damage
is serious. Air pollution interferes with the normal circulation of carbon.
Carbon dioxide, methane and ozone occur when fossil fuels are burned. Among
them, Carbon dioxide is the most big problem substance.

Acid rain is
considered rainwater below the PH5.6.

It acidifies the water
and soil extensively, thus destroying plants and killing aquatic organisms. It
also directly damages the leaves of trees and crops to prevent fruit and seeds
from being formed, and acidifies the soil and lakes, which can hurt the ecosystem.
In particular, acid rain kills microorganisms in the soil and dissolves the
inorganic salts necessary for plant growth.

Also, Greenhouse effect followed by air pollution causes the climate
(Seinfeld, J. H.,


Sonar pollution is also noise pollution in
marine environment
The light can be the pollution where no light before. Sea turtle hatching can be
impacted by artificial light heading toward. Instead of ocean they hatch in the
nest on the beach.

organisms which can’t adapt the climate change will suffer from the changing
environment then finally die.


Reduced rain forests due to over capture, destruction, and
environmental pollution, and many creatures are disappearing from the earth,
and the loss of biodiversity can threaten the survival of mankind. There are
more than 30 million creatures living on the earth, including humans. However,
indiscriminate harvesting, destruction, environmental pollution, and so on,
rain forests are gradually diminishing, and many creatures are disappearing
from the earth. If habitat is destroyed 90% of, the number of species will be
reduced by 50%. All species depend on other species for their survival.
Therefore, the species can extinct by the domino effect.


Biodiversity also gives us economic benefits. It is because
human needs, food and shelter, and various industrial products come from the
components of biodiversity. Tamiflu, which was used as a treatment for the H1N1
flu in 2009, was developed as a component extracted from the Chinese plant
called ‘Octagonal Fennel’. At that time, a US company that manufactured Tamiflu
was able to generate huge sales of 2 trillion won a year.

Biodiversity increases with the diversity of genetically diverse traits, the
more species you live in a region, the more forests, swamps, and wildlife you
live in.
