Lima,the capital of Peru,is the world's second largest desert city.The region is water-stressed.The annual rainfall is less than 4cm.Access lo water is an ongoing problem for the residents in and around the capital.
When industrial engineer Abel Cruz was a boy,his weekly work was to climb down a valley in the foothills of the Peruvian Andes to fetch the family's water from a spring."It was downhill from the house, ar away and steep,"he says.Cruz began dreaming up better ways to collect water,noticing that subtropical plants capture rain and mist with their wide leaves.Actually Lima doesn't lack humidity( 湿 度),averaging 83%year around.Located in the foothills of the Andes Mountains,it is close to the Pacific Ocean,which insures that blankets of dense fog roll in for three quarters of a year.Eventually,Abel Cruz struck upon the idea of a fog net.
Each vertical net is 20 square meters of synthetic resin mesh(合成树脂网),where micro-droplets of water suspended in the foggy atmosphere condense ( 凝 结 ) and drip down into collction tanks. Approximately 200 to 400 liters of water can be collected daily from each net.Locals can fetch it in buckets for small-scale farming.Working in Lima with support from the Creating Water Foundation,Cruz has installed over 3,600 nets on hillsides around the city to capture fog drifing in from the Pacific Ocean.Cruz raises funds for hundreds of nets in Peru with his revolutionary initiative Peruvians Without Water.He aims lo set up even more fog harvesters,and to treat the water to make it drinkable.
“The planet has less and less fresh water,"Cruz points out,"because the glaciers that are nalural reservoirs are disappearing.So we must find a way to accumulate and save waler for times of drought."The lechnology is life-changing for the poor households who normally have to rely on water tanks being delivered lo them.His approach alleviates extreme poverty and brings rural development.Moreover,he is trying to bring healthy and clean water also to urban areas lacking waler.
24.Why does the author mention Cruz's childhood experience in paragraph 2
A.To illustrate the urgency of reducing poverty. B.To highlight his responsibility for the family.
