Understanding this transition requires a look at the two-sided connection between energy and human well-being. Energy contributes positively to well-being by providing such consumer services as heating and lighting as well as serving as a necessary input to economic production. But the costs of energy — including not only the money and other resources devoted to obtaining and exploiting it, but also environmental and sociopolitical impacts — detract from well-being.For most of human history, the dominant concerns about energy have centered on the benefit side of the energy-well-being equation. Inadequacy of energy resources or more often of the technologies and organizations for harvesting, converting, and distributing those resources has meant insufficient energy benefits and hence inconvenience, deprivation and constraints on growth. The 1970’s，then, represented a turning point. After decades of constancy or decline in monetary costs — and of relegation of environmental and sociopolitical costs to secondary status — energy was seen to be getting costlier in all respects. It began to be probable that excessive energy costs could pose threats on insufficient supply. It also became possible to think that expanding some forms of energy supply could create costs exceeding the benefits.

Sea rise as a consequence of global warming would immediately threaten that large fraction of the globe living at the sea level. Nearly one-third of all human beings live within 36 miles of a coastline. Most of the world’s great seaport cities would be （1 ）: New Orleans, Amsterdam, Shanghai, and Cairo. Some countries — Maldives Islands in the Indian Ocean, islands in the Pacific — would be inundated. Heavily populated coastal areas such as in Bangladesh and Egypt,（2）large populations occupy low-lying areas, would suffer extreme （3） .Warmer oceans would spawn stronger hurricanes and typhoons, （4）in coastal flooding, possibly swamping valuable agricultural lands around the world. （5） water quality may result as（6） flooding which forces salt water into coastal irrigation and drinking water supplies, and irreplaceable, natural （7）could be flooded with ocean water, destroying forever many of the （8） plant and animal species living there.Food supplies and forests would be （9）affected. Changes in rainfall patterns would disrupt agriculture. Warmer temperatures would （10） grain-growing regions pole-wards. The warming would also increase and change the pest plants, such as weeds and the insects （11） the crops.Human health would also be affected. Warming could （12 ） tropical climate bringing with it yellow fever, malaria, and other diseases. Heat stress and heat mortality could rise. The harmful （13 ）of localized urban air pollution would very likely be more serious in warmer（14）. There will be some （15）from warming. New sea-lanes will open in the Arctic, longer growing seasons further north will （16 ）new agricultural lands, and warmer temperature will make some of today’s colder regions more （17）. But these benefits will be in individual areas. The natural systems 一 both plant and animal — will be less able than man to cope and （18 ）. Any change of temperature, rainfall, and sea level of the magnitude now （19 ）will be destructive to natural systems and living things and hence to man as well.The list of possible consequences of global warming suggests very clearly that we must do everything we can now to understand its causes and effects and to take all measures possible to prevent and adapt to potential and inevitable disruptions（20） by global warming.
