[简答题]At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. 71. Earlier, we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigor and resistance which, though imperceptible at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigor with the passing of time is called aging. It is one the most unpleasant discoveries which we make that we must decline in this way, that if we escape wars, accidents and diseases we shall eventually "die of old age", and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty.

Twelve years ago, oceanographer Captain Charles Moore was skippering his yacht the Alguita in the North Pacific. He sailed into a mass of floating plastic rubbish which took him and his crew a week to cross. This floating rubbish dump is now called the Great Pacific Garbage Patch and doubles the size of the USA.
The United Nations says there are now 18,000 pieces of plastic in every square kilometre of sea everywhere in the world. A walk along any beach will give you some idea of the seriousness of plastic pollution.
The trouble is, when we throw out plastic with the trash, the plastic doesn’t go away. Plastic does not biodegrade. It photo degrades into smaller and smaller particles which then enter the food chain. Plastics contain cancer-causing chemicals along the food chain in increasing concentrations and end up in our fish and chips, along with hormone disruptors.

A. looking at the sea
B. travelling across the USA
C. sailing across the Pacific
