Помогите пожалуйста перевести этот текст,срочно надо! Заранее спасибо большое!!!
A 14-year-old boy grimaces as he struggles to haul a giant fishing net from the angry waves that crash below him. For nine months, Bounali Simamora (Boo-nah-lee See-mamoor-ah) has toiled seven days a week, 10 hours a day, on a rickety fishing pier stranded in the middle of the ocean, 10 miles off the coast of Indonesia. As he sorts his catch, Bounali is careful to avoid the painful sting of jellyfish and sea snakes tangled in the net.
"I work from 8 in the morning until 6 at night", says Bounali, wiping sweat off his forehead as the sun beats down on him. "Every morning, I wake up, sort the fish, dry them. boil them, and put them into storage. Then, I wait for the tide to go down and do it again”
Bounali is of 120 million children worldwide, between the ages of 5 and 14, who are working instead of attending school.
Desperately poor, nearly 80 million of these children sacrifice their health and safety for just pennies a day- or nothing at all.
Many cultures throughout history have forced children to work. Before Congress passed the Fair Labor Standards Act of 1938, countless American children also toiled under brutal conditions.
“Child labor is cheap labor”, says Darlene Adkins of the Child Labor Coalition, an organization that works to end child labor abuses around the world. “Employers can pay children less than adults for the same work. Children are also more easily intimidated and controlled”.
For the thousands of children working on Indonesia's floating fisheries, for example, endless hours of grueling labor often earn them little more than $7 a month.
One-third of these children never receive a penny for labor that often leaves them battered and bruised.
With nothing but aspirin and bandages available to them, those who suffer serious injuries- often as a result of beatings from foremen-have no other choice than to stomach their pain.
Some try to escape the misery by swimming for shore, only to be swallowed by the fierce tides that rip through the ocean. Many kids, like 15-year-old Yuliagi(Yoo-yagee), feel that escape is futile.
“I m sad because all day and all night, we just work”, says Yuliagi. “But the boss said I couldn't go home-they would catch me and bring me to another fishing pier
