Billions of poor people around the world 【小题1】 (depend) on the use of wood for cooking. And as they take more and more firewood from wild areas, they are destroying habitats around the world. Wood collection is one reason why many animals have become endangered. This is 【小题2】 Dr. Metcalf spends each summer in Africa. He wants to teach women and children in villages how to cook with the sun. He helped create Solar Cookers International.

China's online food delivery platform Ele.me has carried out a new service of picking up garbage from its users in Shanghai 【小题1】 July 2019.

The service comes after 【小题2】 recently-released regulation on waste management in Shanghai. Individuals 【小题3】 throw away their garbage without sorting it can be fined up to 200 yuan, while companies and 【小题4】 (organize) can face fines up to 5,000 yuan.

The trash taking service requires residents to sort 【小题5】 (they) own garbage before it 【小题6】 (pick) up by workers from Ele.me, who will ensure the waste is disposed of in the correct garbage bins.

It's obvious that this service is 【小题7】 (convenience) to the old, especially to the disabled customers.

Ten years ago, Sir Richard Branson launched an exciting challenge. A reward of $25 million would be offered to anyone if he/she 【小题1】(come) up with an achievable and sustainable way to remove greenhouse gases from the air.

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

Drawdown focuses on small, practical steps, not【小题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【小题6】the climate risk. One section of the book, “Coming Attractions”, 【小题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【小题8】(make) the air cleaner. We can make small【小题9】(contribute) like reducing food waste, changing the lightbulbs to LED, installing solar panels and so on.

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