In the 20 years since the Brunddand report, great developments have taken place in industries toward sustainable practices. As a case in point, the problem of acid rain, an issue of concern in 1987, has improved to a large extent, thanks to catalytic pollution abatement both in stationary and automotive emissions. Catalysis for Green Chemistry and Engineering will continue to have a cracial role in improving the environmental performance of industry [25-27]. Nowadays, catalytic procedures are often implemented according to the green chemistry... 

It is essential, therefore, that green plants and the photosynthesising plankton in the oceans be conserved, and that trees and their leaves be allowed to work as efficiently as possible. Leaves should not be clogged up by dirt and grime from pollution, or the trees be stripped of their leaves or made less efficient or smaller by acid rain and photochemical smog. 

As soon as one comes across a green copper roof , one should attempt to remove the green layer until one reaches the pure red-brown copper metal. If one dissolves the green substance in diluted hydrochloric acid, bubbles form. The addition of limewater helps to prove the existence of carbon dioxide. The green substance must be a type of copper carbonate, a completely different substance than the red-brown metal. The formation of green carbonate can be explained by reactions of copper with the solution of carbon dioxide in rainwater, or the formation of blue copper sulfate by the reaction of copper with industrial acidic rain .

In addition to indirect effects from the formation of acid rain, sulfur dioxide affects some plants directly, causing leaf necrosis (death of leaf tissue). Another symptom of sulfur dioxide phytotoxicity (toxicity to plants) is chlorosis, a bleaching or yellowing of green leaves. 

In the 1970s and 1980s, enviromnental laws compelled refineries to reduce emissions of SOx, NOx, CO2, and hydrocarbons. In the atmosphere, SOx reacts with water vapor to make sulfiirous and sulfuric acids, which return to earth as acid rain. Volatile hydrocarbons react with NOx to make ozone. CO2 is a major green-house gas. To reduce these pollutants, the industry tightened its operation by ...
