Pollution and Biodiversity
There are three types( Air, water and Soil)
Pollution means introduction ofcontaminants into
the environment. Pollution or poisoning of the soil, waterand
atmosphere as a result of excessive use of
chemical fertilizers and pesticides in agriculture
and of certain human activities, especially thoseconnected with industry.

Causes
Deforestation(factories, urbanization cut trees
without replacement.)
Polluted rivers(oil spills,wastewater,chemicals) Sound pollution(Noise lead to mental disturbance)
AirPollution(sulphurdioxide, coal, gases, smog)
Soil pollution(dumping of waste- agriculture)

Impacts
The atmosphere, lithosphere, and hydrosphere are
negatively affected by pollution
Growing pollution poses mounting problems forpublic health.(tuberculosis, malaria, and diarrheal
diseases, among othersand now HIV/AIDs).
Air pollution affects lower life forms more than
higher life forms.P
lants are generally moreaffected than animals on land, but not in fresh
water.

Impacts
Air pollution also changes the distribution of many
plants species and plant communities.
Many of our forest ecosystems will be destroyed orat least be disturbed, resulting in considerable
changes in plant communities and losses of plant
resources and ecosystems.

Controlling Pollution
Something needs to be done to reduce pollution at thesource.
Reducing energy demands,
conserving energy, switching of fuel. Technical pollution controls.(water plant recycling
system)
Protect Coastal birds and mammals from oilPollution.(e.g. Patagonia)
Policies Education and sensitization
Controlling population growth.

Conclusion
We have to consider about CO2 reduction to protect
biodiversity.
Carbon foot print help us to see how much exhaustgreenhouse gas.
We have to be responsible for exhausted CO2.

What is Biological Conservation
In general biological conservation means activemanagement of the survival of the maximum diversity ofspecies and maintenance of genetic variety within species.Or conservation means act or practice of conservation,protection and preservation of species which is going to be
extinct BC Started from 1900s with development of fisheries,forestry, wildlife management, along with the first modernland of ethic. Establishment of ecology and biogeographyduring the 1960s and 1970s on scientific foundation forconservation .
BCConcerns raising on growing evidence of the massiveextinction of species within the biological community withthe threat of dooming g up 20.000 species could be lostor doomed every year due to human activity.

Causes and impact of extinction
Threatened species are likely to be Endangeredspecies due to habitat destruction( breeding sites,competition for nutrients and space, physical features,and process of natural calamities and deforestationsuch a mass number of logging), invasive
species(cover space and nutrient from native species),pollution and over exploitation.
Impact of human activities on over exploitation ofmammals, birds, vegetation, marine species andforest condition
endangered species are prone to affect easily bydisease or emergence of new species throughcompetition on resources, changes on carryingcapacity and ecosystem

How can we manage?
Big campaign is going on not killing shark and whale
for meat and maintain habitat, elephant for tusk andskins
Stop on over utilization and exploitation

Conclusion
Biodiversity is important in human-managed as
well as natural ecosystems.
The Earth could not sustain current level of
development.
