The document discusses several issues with burning fossil fuels for energy, including the release of large amounts of carbon dioxide and sulfur dioxide that cause global warming, acid rain, droughts, and floods by raising average global temperatures. It also notes problems like pollution, the development of smog, and damage to the ozone layer. While nuclear energy produces dangerous radioactive waste, the document advocates conserving fossil fuels and developing alternative energy sources like wind, hydroelectric, solar, tidal, geothermal, and biomass energies since fossil fuel reserves are limited and will be depleted within 40-200 years.

4. • The burning of fossil fuels release a huge amount of co2 and so2 in the
atmosphere
• Co2 causes global warming while so2 cause acid rain.
• The avg: temp: of earth will rise which will lead to
• Droughts.
• Hurricanes, storms and flood would occur.

Problems with burning of fossil fuels

5. Problems with fuels
• Due to huge amount of CO2 liberation green
house effect occur which in result to an
earth full of environmental problems
• Other problems like lead poisoning, dust
and gases in air lead to smog, and the
development of hole in ozone layer.
• Above Problems may occur due to burning
of fossil fuels.
• Nuclear fuels produce extremely dangerous
radioactive rays which remain active for
thousands of years and have caused several
disastrous accidents.

6. WHY TO CONSERVE Energy ?
We have limited fuels available on Earth and the demand is increasing
day by day.
Industrialized country need large amount of energy most of this energy
comes from fossil fuels which are non renewable.
Crude oil will only last for 40 years, gas for 60 while after 200 years we
will run out of coal.
So the only solution is to Conserve energy by limiting its use and by using
the alternate energy sources

7. We can conserve energy by conserving fossil fuels and by using alternative energy sources.
Fossil fuels could be saved from domestic to
industrial level by reducing its unnecessary use
and by using alternate sources.
