4. Environmental issues in Delhi
•Overcrowding and the ensuing overuse of scarce resources suchas
water put heavy pressure on the environment. ...
•Noise pollution is primarilya result of motorcycleand automobile
traffic. ...
•Air pollution in Delhi is causedmainly by industry and vehicles.

6. The most basic solution
for air pollution is
to move away from fossil
fuels, replacing them
with alternative
energies like solar,

7. Cleaning Smokestacks and Exhaust Pipe
The leading sources of air pollution are power
plants, factories, and vehicles. They constantly emit
fumes and gaseous waste into the atmosphere. In
power plants and manufacturing industries,
electrostatic smoke precipitators that use static
electricity to trap soot and dust from the gaseous
waste leaving the smokestacks is a significant
technological cleaning measure which can be used to
control air pollution.
Flue-gas desulfurization (FGD), commonly referred
to as scrubbing, is as well another means of
providing a technical solution to Sulfur Oxide
emissions. Scrubbing is a process that chemically
eliminates the sulfur oxide gasses leaving the
smokestacks. Power plans can also be retrofitted
with carbon capturing technologies that trap emitted
carbon dioxide.
Vehicles with gasoline powered engines are fitted
with catalytic converters on the exhaust pipe to
reduce the exhaust gas emissions. Constant
improvements to gasoline that combusts cleaner and

8. Use of Renewable or Green Energy Sources
Fossil fuel and coal are the main contributors
to air pollution. Therefore, opting for
alternative or renewable energy sources to
produce power presents a practical solution to
air pollution. Alternative energy sources
include wind energy, geothermal energy, solar
energy, and hydro-power. If people can
harness a variety of these energy sources
instead of relying on fossil fuels or coal energy,
air pollution can reduce more than threefold.
Natural gas, fuel cells, and batteries can as
well substitute the use of fossil fuels as
cleaner energy sources. Still, it is important to
evaluate correctly some of these alternative
energy sources because aside from their
benefits, some of them come with different

9. Individual Level Prevention Methods
Multifarious ways can be used at the individual level to reduce or
prevent air pollution. Foremost, individuals who are aware of the
causes and effects of pollution can encourage family, friends, or
colleagues to use the bus, train or bike when moving from one place
to another. For shorter distances, it is even better just to walk or
ride a bike. By doing so, there will be lesser vehicles on the road and
as such, less emission
Energy conservation by using energy wisely is also a viable individual
measure for reducing air pollution. The logic here is that high
amounts of fossil fuels are burned to produce the energy used for
cooking, heating, or lighting. In this sense, saving energy cuts down
air pollution. Another measure is re-using some of the utilities we
