The concept of obtaining fresh water from icebergs that are towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. Three-quarters of the Earth’s fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes, rather, they are formed entirely on land. breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. To corral them and steer them to parts of the world where they are needed would not be too difficult. The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalinization, or removing salt from water. With which of the following ideas would the author be likely to agree
中国作为一个发展中国家，面临着发展经济和保护环境的双重任务。然而，我国人口众多，资源向对不足，经济规模越来越大，经济发展与资源和环境之间的矛盾日益突出。环境污染严重，生态状况恶化、资源耗费巨大、回收率低而导致环境破坏等问题，已成为中国经济保持可持续发展的瓶颈。 从国情出发，中国在全面推进现代化的进程中，已将环境保护视为一项基本国策，将实现经济可持续发展视为一项重要战略，同时在全国范围内开展污染防治工作和生态环境保护活动，环境恶化的状况基本得到了控制。实践证明，我们协调经济发展与环境保护两者之间关系的做法是行之有效的。人类发展只有合理地利用自然界，与自然界保持和谐关系，才能维持和发展人类所创造的文明，才能与自然界共生共荣、协调发展。中国作为国际社会的成员，在努力保护自己环境的同时，还积极参与国际环保事务，促进国际环保合作，并认真履行国际义务。所有这些都充分表明了中国政府和人民保护全球环境的诚意和决心。
