An Introduction to Global Environmental Issues presents a comprehensive and stimulating introduction to the key environmental issues presently threatening our global environment. The rapid growing population and economic development is leading to a number of environmental issues in India because of the uncontrolled growth of urbanization and industrialization, expansion and massive intensification of agriculture, and the destruction of forests. Major environmental issues are forest and agricultural degradation of land, resource depletion (water, mineral, forest, sand, rocks etc.), environmental degradation, public health, loss of biodiversity, loss of resilience in ecosystems, livelihood security for the poor.

4.  It is the layer of air around the surface
of the Earth which protects us from
harmful Ultraviolet Radiations emitted
by the Sun.
 It blocks the UV Rays from entering
into the Earth's atmosphere.
 However, various factors such as air
pollution, deforestation, CFCs etc. have
led to the depletion and damage of this
protective layer.
AEM

5.  This process repeats again and again depleting the ozone layer and causing holes in
it which allows the harmful UV radiations to enter the earth’s surface.

6. Eye Diseases
Skin Cancer and other skin related diseases
Causes damage to aquatic life (fish, crabs)
Affects plants
Poses risk for animal health

7. Global warming is the current
increase in temperature of the
Earth's surface (both land and
water) as well as it's atmosphere.
Over the span of past 50 years the
global average temperature has
increased by 1.1 degree Celsius.
AEM

8.  Global warming occurs when carbon dioxide
(CO2) and other air pollutants and
greenhouse gases collect in the atmosphere
and absorb sunlight and solar radiation that
have bounced off the earth’s surface.
 Normally, this radiation would escape into
space—but these pollutants, which can last
for years to centuries in the atmosphere,
trap the heat and cause the planet to get
hotter.
 That's what's known as the greenhouse
effect.

11.  India has experienced a dramatic growth in fossil fuel
CO2 emissions, and the data compiled by various
agencies shows an increase of nearly 5.9 % since 1950.
 At present India is rated as the 6th largest contributor of
CO2 emissions behind China, the 2nd largest
contributor.
 Our per capita CO2 of 0.93 tons per annum is well below
the world average of 3.87 tons per annum. Fossil fuel
emissions in India continue to result largely from coal
burning.
 The national inventory of greenhouse gases indicates
that 55% of the total national emissions come from
energy sector.

12. Climate change has become more than obvious over
the past decade.
The rise in temperature has also ensured that the
equations on the planet have been disturbed.
Some of the most obvious signs of this are-
 Frequent storms
 Melting glaciers
 Rising levels of sea
Going by the prevailing conditions, it is not difficult
to anticipate that the planet is heading for a
dramatic climate change, some wherein, near,
future.

Warming Oceans
Shrinking Ice Sheets
Glacial Retreat
Decreased Snow Cover
Sea Level Rise
Ocean Acidification

14. Population of the planet is growing and,
correspondingly, the amount of waste is
increasing too. If we have a look at
statistics, we will see that there is a huge
area of waste disposal all over the world.
Waste disposal sites are a great problem
for the environment of the planet. It
results in additional pollution, holes in
ozone layers, and spread of new diseases.

18.  Signed in Rio de Janeiro by over 150 nations.
 The convention's overall objective is the
stabilization of greenhouse gas concentrations in
the atmosphere at a level that would prevent
dangerous anthropogenic interference with the
climate system.
AEM

19.  Development that meets the needs of the present,
without compromising the needs of the future
generations.
 Use of alternative sources of energy should be
considered where ever possible.
 Non-Renewable sources should avoided as far as
possible.
 More emphasis should be given on the usage of
Renewable Sources of energy as these can replenished
and also do not harm the environment.eg Solar Energy,
Wind Energy, Hydal Energy etc.
AEM

20.  Sustainable transportation has been used for
quite some time now, and it is the means of
transportation that is safe and has a low
impact on the environment.
 sustainable transportation makes use of
renewable energy rather than the use of coal,
petroleum, or other fossil fuels that can cause
an adverse effect on earth.
 Sustainable transportation is safe due to the
fact that it makes use of energy sources that
are renewable.
AEM

21.  Electric cars and trucks are cleaner than most vehicles.
 When battery electric vehicles are powered by the cleanest
electricity grids or when charged exclusively with
renewable electricity like solar or wind, charging and
operating of an electric vehicle then can be nearly emission
free.
 Though electric cars can be more expensive to purchase
than their conventional counterparts but the cost to refuel
an electric car can also be a fraction of the cost of gasoline,
meaning that electric cars can have a lower total cost of
ownership.
 Switching to an electric car can save on average over $700
a year in fueling costs, and over one thousand dollars a
year in some cities.
AEM

22.  Cycling, also known as biking, is the use of
bicycles for transport, recreation, exercise or
sport.
 It is the most environment friendly way to
commute.
 Not only cycling is good for exercise, it also helps
to reduce our carbon footprint.
 Bicycles are the principal means of
transportation in many parts of the world.
 Cycling is efficient and effective mode of
transportation for short to moderate distances.
