Question

The air that we breathe today is more polluted than it was before. More factories, more vehicles, greater u of aerosols and sprays, increasing number of se refrigerators and air conditioners that release CFC gases, have all contributed towards pollution. When certain chemicals from the smoke and fumes rise up into the air, they mix with the water vapour in the c louds and make it acidic. When rain or snow falls from such polluted clouds, it is also acidic in nature. This acidic rain falls on the leaves of trees, on the fertile soil and also runs into lakes and rivers. The effects of this rain are disastrous. Tre es slowly lose their leaves and die. Fertile soil turns acidic and damages the plants and crops. The fish and animal living in lakes or seas are killed. Even our drinking water can be affected. Many forests all over the world have suffered severe damage on account of acid rain. Before it is too late we must try and put a stop to the millions of vehicles and chimneys pouring harmful fumes into the air. Give a suitable title for the passage​

Answer 2

Answer:

The language is dry and academic, as is appropriate for the abstract of a scientific paper in the prestigious journal Nature. The research described in the short paper, however, fell like a scientific bombshell, one whose repercussions would be felt around the world. It set off fierce debates, led to a global environmental treaty restricting the use of a broad class of chemicals, and changed the way humans viewed their impact on Earth’s environment. It also led to F. Sherwood Rowland (1927-2012) and Mario J. Molina (*1943) sharing the 1995 Nobel Prize in Chemistry with Paul J. Crutzen of the Max Plank Institute for Chemistry, Mainz, another pioneer in stratospheric ozone research.

Rowland, a professor of chemistry at the University of California, Irvine, and Molina, a postdoctoral fellow in Rowland’s laboratory, had shown that chlorofluorocarbons—CFCs—could destroy ozone, a molecule made up of three oxygen atoms, O3, in Earth’s stratosphere. That stratospheric ozone absorbs ultraviolet radiation that otherwise would reach the surface of Earth. At the time, CFCs were in wide use in refrigeration, air conditioning and aerosol spray cans. The compounds are inert and essentially nontoxic, characteristics that made them well-suited for these applications. These same characteristics, however, also made them a danger to life on Earth.
