Ten years ago, Sir Richard Branson launched an exciting challenge. A reward of $25 million would be offered to anyone if he/she     1    (come) up with an achievable and sustainable way to remove greenhouse gases from the air. He thought such an innovation would soon come true, and that    2    (power) people like him would carry out a top-down solution in one fell swoop (一下子).

No such situation appeared, not even with the massive reward. But all is not lost. Branson believed everyone could participate in    3     (save) humanity; it wouldn't be a task for just a few superheroes. It was the spirit    4     inspired Paul Hawken and a network of researchers to come up with the book, Drawdowns.

Drawdown focuses on small, practical steps, not    5    (possible) solutions. Hawken's researchers collected data, information and practical knowledge, creating what is something of an encyclopedia (百科全书) of solutions    6    the climate risk. One section of the book, “Coming Attractions”,     7    (look) at solutions that we are close to getting a handle on, and they are likely to be useful ones for the near future. Not a daydream, in other words,

Just as it says in this book, we can't just build a piece of big equipment    8    (make) the air cleaner. We can make small    9    (contribute) like reducing food waste, changing the lightbulbs to LED, installing solar panels and so on.

We are living in     10    interconnected world, so we need to think about the community, about the common interests of many individuals inhabiting a single planet.

4 . An extraordinary new restaurant in Semarang, Indonesia is on a mission (使命) to support locals trapped in poverty, many of whom are earning less than $25 a month, by providing them with an alternative way to pay for their food.

The Methane Gas Canteen, run by husband and wife team Sarimin and Suyatmi, is located in an unexpected place for an eatery — Jatibarang Landfill. The landfill is a mountain of purifying waste, where poor locals spend their days collecting plastic and glass to sell. Meanwhile, the couple, who spent 40 years collecting waste before opening the restaurant, is busy cooking.

What makes the restaurant unusual, aside from its location, is that no cash is required to pay for meals. Poor people have the option to pay for their food with recyclable waste instead of cash. Sarimin weighs the plastic customers bring in, calculates its worth, and then deduct that value from the cost of the meal, giving any extra value back to the customer. The scheme is part of the community’s solution to reduce waste in the landfill and recycle non-degradable plastics.

“I think we recycle 1 ton of plastic waste a day, which is a lot. This way, the plastic waste doesn’t pile up, drift down the river and cause flooding,” said Sarimin in an interview with Channel News Asia. “It benefits everyone.”

The restaurant seats about 30 people and serves meals that cost between $0.40 and $0.80 each. Since opening the canteen Sarimin and Suyatmi have seen their daily income more than double to $15 a day.

“I’m happy to see our customers enjoying their meals,” Sarimin told NHK World. “The poor must also have the right to enjoy healthy eating. I want to give them that chance as much as possible.”
