    Climate scientists have recently reported that the polar ice caps are melting due to a rise in atmospheric temperatures known as the ‘Greenhouse Effect’. According to them, the carbon dioxide given off when coal and oil are burned is accumulating in the atmosphere and causing temperatures to rise. As a result, the ice covering the North and South Poles is melting and may eventually lead to a rise in sea levels which could flood many areas of the world including New York, London and Tokyo.

    The ‘Greenhouse Effect’ is just one of many fundamental changes which are taking place in the environment. Tropical rain forests, which took fifty million years to grow, are being reduced at the rate of fourteen acres per minute. The world’s deserts are growing year after year. Scandinavia’s beautiful lakes are becoming lifeless due to acid rain caused by sulphur dioxide emissions from factories in the west of Germany and Britain. Many species, therefore, are in danger of extinction.

    In the same respect, another famous climate specialist said, “World population growth, the degradation of the Earth’s natural resources and the spread of environment pollution collectively threaten the welfare of mankind”. He added, ‘Words alone, however, will not solve the problem.  If governments do not act quickly and decisively to protect the environment, our planet will soon become uninhabitable”.

    3-What or who do the underlined words in the text refer to?
    them§1 →                                     He §3→
