Global Warming Global Warming is the average
increase in the temperature of earth’s surface.
Global warming occurs as a result of increased emissions of greenhouse gases from human activities.
Human caused pollutions and emissions are the leading cause of global warming.
Global warming has melted the polar ice caps, raised the levels of the Oceans and flooded the earth’s great cities.
Air Pollution
Transportation is the largest single source of air pollution
With the number of vehicles on the road, we are on the fast lane to smoggy skies and dirty air.
Air pollution is associated with full life cycles of Cars and Trucks.
Motor vehicles cause both primary and secondary pollution.
i) Primary Pollution It is emitted directly in to the atmosphere.
ii) It results from chemical reactions between pollutants’ in the atmosphere.
Major Pollutants’ from Motor vehicles:
Hydrocarbons, Nitrogen Oxides (NO), Carbon monoxide (CO) and Sulphor Oxides
Carbon Monoxide (C0) : 47%Sulphor Oxide (SO2) : 15%Hydrocarbons : 15%Particulates : 13%Nitrogen : 10%
Pollution due to Factory Outlets.
The release of chemicals and particles into the atmosphere produced by the industries cause the air pollution.
The discharge of waste water from commercial and industrial waste into surface water (Water Pollution)
Soil contamination occurs when chemicals are released by factories.
The industrial noise cause permanent hearing damage.
Solar Energy.
Solar energy is a clean alternative energy source which is good for planet.
Solar water heating is one of the major alternative energy for the future.
It is an energy source, will work for most Domestic/Industrial and provide hot water, lighting through out the year.
Health Problems from pollution
