2. HUMAN IMPACT ON ENVIRONMENT

3. HUMAN IMPACT ON ENVIRONMENT MEANS
OVER POPULATION POLLUTION
Overpopulation has grown into an epidemic since
mortality rates have decreased, medicine has improved,
and methods of industrial farming were introduced, thus
keeping humans alive for much longer and increasing the
total population.
Pollution is so bad that to date, 2.4 billion
people do not have access to clean water
sources. Humanity is continuously polluting
indispensable resources like air, water, and soil
which requires millions of years to replenish.

4. HUMAN IMPACT ON ENVIRONMENT MEANS
GLOBAL WARMING
CLIMATE CHANGE
Global warming is arguably the greatest cause of
impact to the environment. The largest of causes
emanating through CO₂ levels from respiration to
more detrimental causes like burning fossil fuels
and deforestation.
Climate change is closely connected to
historical developement of industry and
technology. As global temperatures
increase, Earth's weather patterns will
drastically change.

5. HUMAN IMPACT ON ENVIRONMENT MEANS
GENETIC MODIFICATION OCEAN ACIDIFICATION
GMO's are selected bred crops or crops that have
had DNA directly implanted into it in order to give an
advantage to the crop, whether that be to sustain
colder temperatures, require less water, or yield more
product.
Ocean acidification is caused when CO₂
dissolves into the ocean bonding with sea
water creating carbonic acid.

6. HUMAN IMPACT ON ENVIRONMENT MEANS
WATER POLLUTION
DEFORESTATION
Every year over 8 millions tons of
garbage dumped into the ocean. Not only is
garbage introduced into the oceans, but also
the excessive amounts of fertilizer that finds its
way into the ocean through rains, floods, winds,
or dumped in excess right into the largest
producer of oxygen we have.
With an exponential expansion in human beings, more
food, materials, and shelter are being manufactured at
stupendous rates, mostly stemming from
forestry. Forests are cleared to make way for new
humans, which in turn, makes more humans, you can
see the problem.

7. HUMAN IMPACT ON ENVIRONMENT MEANS
ACID RAIN
OZONE DEPLETION
When humans burn coal, sulphur dioxide and
nitrogen oxides are released into the atmosphere
where they rise up and accumulate in the clouds
until the clouds become saturated and rain acid,
causing havoc on the ground beneath.
The ozone layer is renowned for its ability to
absorb harmful UV rays that would otherwise
be detrimental to the health of all walks of life.
Without an ozone layer, walking outside would
be unbearable.

बहुत लुभाता है गर्मी र्में,
अगर कह ींहो बड़ का पेड़।
निकट बुलाता पास नबठाता
ठीं ड छाया वाला पेड़।
तापर्माि धरत का बढ़ता
ऊीं चा-ऊीं चा, निि-निि ऊीं चा
झुलस रहा गर्मी से आींगि
गाींव-र्मोहल्ला कीं चा-कीं चा।
गरर्म र्मधुर्मक्ख का छत्ता
जैसे निया नकस िे छेड़।
आओ पेड़ लगाएीं नजससे
धरत पर फै ले हररयाल ।
तापर्माि कर्म करिे को है
एक यह ताले क ताल
ठीं डा होगा जब घर-आींगि
तभ बचेंगे र्मोर-बटेर
तापर्माि जो बहुत बढ़ा तो
ज िा हो जाएगा भार
धरत होग जगह ि अच्छ
पग-पग पर होग ब र्मार
रखें सींभाले इस धरत को
अभ सर्मय है अभ ि िेर।
