据科学家预测,在未来20年里,我们在科学技术领域将会有重大突破,有许多科学难题将被攻克,人类将迈向一个充满希望的新世纪。环境——氟利昂完全消失,将被其他对臭氧层无害的物质所替代。有一半的生活垃圾被再利用。大多数工厂都将采用环保措施,最大限度地减少环境污染。绝大多数产品采用的原料是可以回收利用的。能源——地热、水力、太阳能等替代性能源将在全球能源利用中占有重要比例。以农作物、树木等有机物质为主的有机能源将占地球总能源的10%。核发电产生的电能将占电能总量的50%。将燃料能转换成电能的燃料电池的利用率将达30%。
According to scientists' prediction, in the next 20 years, we will make major breakthroughs in science and technology. Many scientific problems will be overcome and mankind will move toward a new century full of hope. Environment - The complete disappearance of freon will be replaced by other substances that are not harmful to the ozone layer. Half of domestic waste is reused. Most factories will adopt environmental protection measures to minimize environmental pollution. The vast majority of products using raw materials can be recycled. Energy - Alternative energy sources such as geothermal, hydro and solar energy will hold a significant share of global energy use. Organic energy such as crops, trees and other organic substances will account for 10% of the total energy of the earth. Nuclear power generation will account for 50% of the total energy. Utilization of fuel cells that convert fuel to electricity will reach 30%.
