On May 2, 2012, Ashok Gadgil became the winner of the $100,000 Lemelson-MIT Award for Global Innovation (全球创新奖). Each year, the honor is given to an inventor who has made a big difference in the lives of people in developing countries. Gadgil is a professor and physicist at the University of California, Berkeley. He spent thirty years helping people in need. His inventions have helped more than 100 million people around the world. “I chose to focus on problems where my knowledge of science could help,” Gadgil said.

In the 1990s, Gadgil designed his first life-saving invention after more than 10,000 people died from Bengal cholera (孟加拉霍乱) because of the clean water crisis (危机) in India. His invention uses ultraviolet light to kill deadly disease-carrying germs (细菌) from drinking water. It costs just one cent to clean five liters of water (about 21 cups). So far, the invention has provided safe drinking water for more than five million people in India and other developing countries.

Gadgil’s another important invention is the Berkeley-Darfur Stove (炉具). The long and violent war in Darfur, Sudan, has caused many people to move to foreign countries and live in refugee camps (难民营). They are given food aid. But people still have to travel a long distance five times a week to gather firewood to cook meals. This can be dangerous because of street violence in the area. To avoid danger, some spend much of their money used to feed their families buying firewood.

The stove Gadgil created cuts fuel usage by 55%. That means people wouldn’t have to leave the camps to find firewood as often. The invention also helps to save homes more than $300 a year. About 125,000 people and their families have been helped.

As a professor, Gadgil encourages his students, “Be optimistic (乐观的) when you try a hard problem,” he says. “It’s when you solve a large problem that you can have a big influence on the world.”

When do you think of a forest, what do you see? Just trees Or do you see many other things, such as singing birds, colorful plants and wild flowers?

    The forest is a whole world of its own. It is full of many different living things (生物). But even thoughthey are all different, they have one thing in common: they all need each other in order to live on. 

    The trees feed the forest "people" by making food in their leaves; by using sunlight to join water and minerals(矿物) from the soil and air. Their deep network of roots Joins the soil together and stops it from  dying out, making it possible for living things to live in it. Human beings (人类) are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks (售货员) to sell it to us. We need people to prepare our food and

cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government  leaders, mailmen, telephone operators, and many others. We also need other human beings in another way. 

We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone. 

     Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else. You know,  being a volunteer is so great!
