INTRODUCTION
WE ALL ARE SMOKERS…ARE WE?Daily activities=cigarette
We are=smokers
CURRENT SCENARIO
•Post industrial revolution era
• % of CO2 emissions is on a steady rise
• The CO2 levels are reaching alarming levels
AIM• Lay man awareness how does he contribute to Carbon emission
• The hazards of the same on personal level as well as to the whole world and
• Suggest small and simple steps that we can take to prevent carbon emissions .
CARBON FOOTPRINT• A carbon footprint is "the total set of greenhouse gas (GHG) emissions
caused directly and indirectly by an individual, organization, event or product".
A Carbon Footprint is made up of two parts:• The primary footprint is a measure of our direct emissions of CO2 .
• The secondary footprint is a measure of the indirect CO2 emissions
The pie chart above shows the main elements whichmake up the total of a typical person's carbon footprint in the developed world.
GREENHOUSE GASES ARE INDISPENSIBLE
• One-third of the solar energy is reflected directly back to space
• Remaining two-thirds is absorbed by the surface and, to a lesser extent, by the atmosphere
• To balance Earth radiates the same amount of energy back to space
• But the Earth is much colder than the Sun, it radiates at much longer wavelengths
• Atmosphere acts as a one way valve.
• The two most abundant gases in the atmosphere, nitrogen and oxygen exert almost no greenhouse effect
• But gases such as CH4 & CO2 are green house gases.
GREENHOUSE EFFECT IS NOT A BAD
The temperature of the surface of the Earth would be -18°C, instead of the actual value of about 15°C
MAIN WORRY
• The amount of radiation which escapes depends on the concentration of
greenhouses gases in the atmosphere.
• Earth’s Temperature has increased by 0.6°C ± 0.2°C over the last century
PROBLEM
unchecked emission of Greenhouse gases (mainly CO2) in atmosphere.
…INCREASE IN ATMOSPHERIC LEVELS
