Environmental Issues

• Environmental issues are harmful aspects of human
  activity on the environment.
• It can effect the environment in various ways .
  Environmental issues are mainly the following
• Air- related Environmental issues
• Water-related Environmental issues
• Land -related Environmental issues

Air-related Environmental problems

• Air Pollution

5

• Air pollution is the most dangerous form of
  pollution.
• Air pollution is the mixture of solid particles
  and gases in the air.
• Car emissions , chemical from factories , dust
  etc . are the main particles that are suspended
  in the air and cause pollution. These suspended
  particles are called pollutants.
• Even smoke from burning leaves and cigarettes
  are harmful to the environment.

6
Global Warming
7

• Global warming is the increase in earths average
  temperature due to increased trapping of infrared
  radiations by green house gases.
• It is a result of increased pollutions and other
  phenomenon that increases the amount of green
  house gases in the atmosphere.
• As a result the glaciers are melting and the sea
  level is accelerating , large wildfires are
  growing and severe droughts are occurring.

8
WATER-RELATED ENVIRONMENTAL ISSUES

• Water Pollution

9

• Water pollution is caused due to industrial waste
  released into lakes , ponds and other water
  bodies.
• Humans pollute water with large scale disposal of
  garbage , flowers , ashes and other household
  waste.
• Acid rain further adds to the water pollution.
• Water pollution can result in depletion of
  dissolved oxygen in water bodies.
• Water pollution can also occur as a result of
  soil pollution.

10
Acid rain
11

• Acid rain is a rain that is unusually acidic
  that can have harmful effects on plants , animals
  and infrastructure.
• Acid rain is a result of air pollution.
• When any type of fuel is burnt, lots of different
  chemicals are produced. Some of these gases
  (especially nitrogen oxides and sulphur dioxide)
  react with the tiny droplets of water in clouds
  to form sulphuric and nitric acids. The rain
  from these clouds then falls as very weak acid -
  which is why it is known as "acid rain".

12
LAND-RELATED ENVIRONMENTAL ISSUES

• Soil Pollution

13

• Soil pollution is a result of acid rain ,
  polluted water , fertilizers , disposal of waste
  , mining activities etc..
• Soil contamination occurs when chemicals are
  released to the soil in the form of fertilizers ,
  pesticides ,etc..
• Soil pollution can effect the growth of crops and
  plants in the soil.
• The toxic chemicals present in the soil can
  decrease the soil fertility.

• Its time to join hands across the globe to
  protect preserve and save the mother earth
  environment
• First
• Carbon footprint is the total amount of green
  house gases produced by an organization or a
  person , in other words reduce pollution , usage
  of vehicles , factories ,etc..

25

• PLANT TREES !!! AND STOP DEFORESTATION!!! , it is
  the biggest solution for all the environmental
  issues.
• Try combining driving with alternative modes of
  transportation.
• Understand the concept of Reduce , Reuse and
  Recycle.
• Use energy efficient devices.

26

• Reduce the use of chemicals like fertilizers ,
  pesticides in agricultural activities.
• Avoid using non biodegradable products for
  example plastic.
• Finally CONSERVE ENERGY !!! CONSERVE WATER !!
  RECYCLE THE WASTE AND USE RENEWABLE RESOURCES
