HARVESTING ICE

1 Though harvesting ice is not a new concept, recently it has

been considered in a way.

2 Scientists have been studying this idea of harvesting ice as a

possible solution to the problem of the worlds dwindling fresh

water supply.

3 Ninety percent of the earths fresh water is in the icecap of

Antarctica.

4 If only 10 percent of that ice could be towed to civilization, it

could provide water for 500 million people.

5 But the problem, of course, is one of melting. How can a giant

iceberg be towed across the sea without melting?

6 The answer could lie in enclosing the floating ice in a huge

cylindrical container made of a high strength synthetic fabric.

enclose something (in/with something) /nklz/ (v): to build a

wall, fence, etc. around something: ro quanh

cylindrical /slndrkl/ (adj): c hnh tr

7 If the iceberg were nudged into the fabric container, which is

opened at both ends, then the ends could be sealed and the sea

water pumped out.

gradually in a particular direction

cocoon would act a holding tank for the water.

one kilometer in length and 100 meters in diameter, would be a

feat, but engineers say it is possible.
