  • dry Yamuna would weaken the wood-based foundation of the Taj Mahal, which requires moisture.
  • Blaming pollution and regulatory negligence for the Taj’s decay, Mahesh Chandra Mehta, a prominent environmental lawyer, filed a case before the Supreme Court of India in 1984. In August 1999, the Supreme Court struck ordering the closure of 53 iron foundries and 107 other factories in Agra that had not cleaned up their act. The order has become a call to arms for foundry owners, workers, trade union representatives and small-scale industry. In the meantime, Agra’s Iron Founders’Association are building up their case. They argue that 3,000 cottage and engineering units depend on the foundries, and that about 300,000 workers are directly or indirectly employed by them. They hold that the technology for using natural gas in their industries is not yet ready. Mehta claims that this is a “delaying tacticThe Hon'ble Supreme Court after examining all the reports were the active contributors to the air pollution in the said area. All the 292 industries were to approach/apply to the GAIL before 15.2.1997 for grant of industrial gas-connection. The industries which were not in a position to obtain gas-connections, to approach UPSIDC before 28.2.1997, for allotment of alternative plots in the industrial estates outsideThose industries, which neither applied for gas-connection nor for alternate industrial plots should stop functioning using coke/coal as fuel in the TTZ w.e.f. 30.4.1997. The supply of coke/coal to these industries shall be stopped forthwith
  • ALL INDIAN MONUMENTS ARE NOT AS LUCKY AS TAJ TO HAVE SAVIOUR LIKE AD. MEHTA AND MANAGE TO SURVIVE SUFFOCATING IN POLLUTION , IGNORANCE OF CITIZENS AND INEFFICIENCY OF JUDICIARY. Fit scrubbers into factory’s chimneys, which are chemical filters that remove impurities such as sulphur from smoke.Cars can be fitted with special converters which remove dangerous chemicals.Governments need to spend more money on pollution control.Car pooling● Walking● Biking● Public transportation● Non-polluting cars● Using less energy● Conserving paper● Recycling

    • 2. • Acid rain is rain that is more acidic than normal. • Any rainfall has a pH value less than 5.6 is defined as acid rain • Sulfur dioxide and nitrogen oxides, the major sources of acid rain.
    • 3. • Burning coal, Oil and natural gas, in power stations makes electricity, giving off sulphur dioxide gas. • Burning petrol and oil in vehicle engines gives off nitrogen oxides as gases. • These gases mix with water vapour and rainwater in the atmosphere producing weak solutions of sulphuric and nitric acids – which fall as acid rain.
    • 4. • The sulfur dioxide and nitrogen oxide gases, causes respiratory diseases like asthma, chronic bronchitis, etc. • Tiny Particles cause difficulty in breathing for humans and animals & also lead to permanent lung damage. •On Human Health
    • 5. • Acid Rain dissolves all the nutrients and the useful minerals for the tree to grow. • Weakens the process of photosynthesis. • Acc. to modern researches, Acid Rain leaches potassium, calcium, magnesium, etc essential elements from the top of soil & When soil is contaminated, cereal (arable) production crops. • Acids activate aluminium from the soil which leaches into water and fish die. Drinking water is contaminated.
    • 6. • Acid Rain increases the acidity of lakes & rivers, which is directly effect the aquatic ecosystem.
    • 8. • White starts to go yellow • Precious and semi precious stones of the Taj weathered away due to acid rain • The sulfuric and nitric acids in the rain causes the calcite to dissolve and makes gypsum form • Gypsum causes the area of affected stone to turn black and when the gypsum falls off it reveals crumbling stone
    • 10. An example of acid precipitation damage to an outdoor statue. The statue, made of porous sandstone, was created in 1702 as part of the gable of the entrance of the Castle at Herten, near Reclinhausen, Germany. The left photo, taken in 1908, shows some stains and the loss of the left hand, but most of the face and right hand were intact after 206 years of exposure. The right photo, taken in 1969, shows the loss of most of the detail of the statue over 61 years
    • 11. •Turn off lights, computers, and other appliances when you're not using them •Use energy efficient appliances: lighting, air conditioners, heaters, refrigerators, washing machines, etc. •Only use electric appliances when you need them. •Keep your thermostat at 68 F in the winter and 72 F in the summer. You can turn it even lower in the winter and higher in the summer when you are away from home. •Insulate your home as best you can. •Carpool, use public transportation, or better yet, walk or bicycle whenever possible •Buy vehicles with low NOx emissions, and maintain all vehicles well.
    • 12. Acid rain is slowly destroying our planet. It is our responsibility to make sure that we protect the earth for future generations to enjoy. We should stop polluting, for example riding your car just to go to your neighbors five houses away from yours, or factories should have filters so that less pollution goes in the sky.
