Read the passage carefully, then choose the correct answers. The search for alternative sources of energy has led in various directions. Many communities are burning garbage and other biological waste products to produce electricity- Converting waste products to gases or oil is also an efficient way to dispose of wastes. Experimental work is being done to derive synthetic fuels from coal, oil shale, and coal tars. But to date, that process has proven expensive. Other experiments are underway to harness power with giant windmills. Geothermal power is also being tested. Some experts expect utility companies to revive hydroelectric power derived from streams and rivers. Fifty years ago hydroelectric power provided one third of the electricity used in theUnited States, but to day it supplies only 4 percents. The oceans are another potential source of energy. Scientists are studying ways to convert the energy of ocean currents, tides, and waves to electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy.

Read the passage carefully, then choose the correct answers.The natural world is under violent assault from man.The seas and rivers are being poisoned by radioactive wastes, by chemical discharges and by the dumping of dangerous toxins and raw sewage. The air we breathe is polluted by smoke and fumes from factories and motor vehicles; even the rain is poisoned.It's little wonder forests and lakes are being destroyed and everywhere wildlife is disappearing. Yet the destruction continues.Governments and industries throughout the world are intensifying their efforts to extract the earth's mineral riches and to plunder its living resources. The great rainforests and the frozen continents alike are seriously threatened. And this despite the warnings of the scientific community and the deep concern of millions of ordinary people.Despite the fact, too, that we can create environmentally-clean industries, harness the power of the sun, wind and waves for our energy needs and manage the finite resources of the Earth in a way that will safeguard our future and protect all the rich variety of life forms which share this planet with us.But there is still hope. The forces of destruction are being challenged across the globe - and at the spearhead of this challenge is Greenpeace.Wherever the environment is in danger, Greenpeace has made a stand.Its scientific presentations and peaceful direct actions at sea and on land have shocked governments and industries into an awareness that Greenpeace will not allow the natural world to be destroyed. Those actions, too, have won the admiration and support of millions.Now you can strengthen the thin green line; you can make your voice heard in defence of the living world by joining Greenpeace today. Thank God someone's making waves.
