The document discusses several types of pollution including air, water, soil, thermal, radioactive, noise, and light pollution. It provides details on air pollution in Delhi, how water pollution occurs from human contamination, sources of soil pollution like chemicals and heavy metals, the effects of thermal pollution like thermal shock on organisms, sources of radioactive pollution from nuclear activities, how noise pollution affects human and animal life, and the effects of light pollution from urbanization. It also discusses deforestation, honey bees, how many trees one person's breathing requires, the connection between humans and nature, and the importance of the Amazon forest for the water cycle, climate stabilization and oxygen production.

1. Pollution

2. Types of Pollution
• The 7 Different Types
• Water Pollution.
• Air Pollution.
• Soil Pollution.
• Thermal Pollution.
• Radioactive Pollution.
• Noise Pollution.
• Light Pollution.

3. Air Pollution(Delhi)
• The air quality in Delhi, the capital territory of
India, according to a WHO survey of 1650
world cities, is the worst of any major city in
the world. It also affects the districts around
Delhi. In Delhi, poor quality air irreversibly
damages the lungs of 2.2 million or 50 percent
of all children.

4. Water Pollution
• Water pollution is the contamination of water
bodies, usually as a result of human activities.
Water bodies include for
example lakes, rivers, oceans, aquifers and gro
undwater. Water pollution results
when contaminants are introduced into the
natural environment.

5. Soil Pollution
• Soil contamination or soil pollution as part
of land degradation is caused by the presence
of xenobiotics (human-made) chemicals or other
alteration in the natural soil environment. The
most common chemicals involved are petroleum
hydrocarbons, polynuclear aromatic
hydrocarbons (such as naphthalene
and benzo(a)pyrene), solvents, pesticides, lead,
and other heavy metals.

6. Thermal pollution
• Thermal pollution is the degradation of water
quality by any process that changes ambient
water temperature. A common cause of
thermal pollution is the use of water as
a coolant by power plants and industrial
manufacturers. Fish and other organisms
adapted to particular temperature range can be
killed by an abrupt change in water
temperature (either a rapid increase or
decrease) known as "Thermal shock."

7. Radioactive pollution
• The radioactive pollution is defined as the
physical pollution of living organisms and
their environment as a result of release of
radioactive substances into the environment
during nuclear explosions and testing of
nuclear weapons, nuclear weapon production
and decommissioning, mining of radioactive
ores, handling and disposal of radioactive
waste, and accidents at nuclear power plants.

8. Noise pollution
• Noise pollution, also known
as environmental noise or
sound pollution, is the propagation of
noise with harmful impact on the activity
of human or animal life. The source of
outdoor noise worldwide is mainly
caused by machines, transport, and
propagation systems.

9. Light pollution
• Light pollution, also known as photo pollution,
is the presence of anthropogenic and artificial
light in the night environment. It is
exacerbated by excessive, misdirected or
obtrusive use of light, but even carefully used
light fundamentally alters natural conditions.
As a major side-effect of urbanization, it is
blamed for compromising health, disrupting
ecosystems and spoiling aesthetic
environments.

10. Deforestation
• Deforestation, clearance, clear
cutting or clearing is the removal of a forest or
stand of trees from land which is
then converted to a non-forest use. Deforestation
can involve conversion of forest land
to farms, ranches, or urban use. The most
concentrated deforestation occurs in tropical
rainforests. About 31% of Earth's land surface is
covered by forests.

11. Honey Bee
• A honey bee (also spelled honeybee) is
a eusocial flying insect within the genus Apis of
the bee clade, all native to Eurasia but spread to
four other continents by human beings.. In the
early 21st century, only seven species of honey
bee are recognized, with a total of 44 subspecies,
though historically seven to eleven species are
recognized. The study of bees, which includes the
study of honey bees, is known as melittology.

12. How many Tress are
needed for an Individual
to Breath?

13. • The average total lung capacity of an
adult human male is about 6 litres of
air. Tidal breathing is normal, resting
breathing; the tidal volume is the
volume of air that is inhaled or
exhaled in only a single such breath.

14. Eight trees
• A human breathes about 9.5 tonnes of air in a
year, but oxygen only makes up about 23
percent of that air, by mass, and we only
extract a little over a third of the oxygen from
each breath. That works out to a total of about
740kg of oxygen per year. Which is, very
roughly, seven or eight trees' worth.

15. Humans and Nature(Connection)
• Humans exert great pressure on the natural
world. Habitats and species suffer not only
from environmental changes caused by
industry and technology, but also from the
strain caused by the world’s massive human
population, which has doubled in the past 50
years and is rising rapidly.
• At the same time, human health and well-being
face huge environmental challenges.

16. Amazon Forest
• The Amazon helps maintain the water cycle
by producing large quantities of rainfall every
year. ...
• The Amazon helps to stabilize the earth's
climate and slow global warming by fixing
CO2 and producing 20% of the world's oxygen
in the process.
