2 . Global warming may or may not be the great environmental crisis of the 21st century, but — regardless of whether it is or isn’t — we won’t do much about it. We will argue over it and may even, as a nation, make some fairly firm commitments (承诺) to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.
Al Gore calls global warming an “inconvenient truth,” as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and — without major technological breakthroughs — we can’t do much about it.
From 2003 to 2050, the world’s population is estimated to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn (注定) the world’s poor people to their present poverty and freeze everyone else’s living standards. With modest economic growth, energy use and greenhouse emissions will more than double by 2050.
No government will adopt strict limitations on economic growth and personal freedom (e.g. electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something”. Consider the Kyoto Protocol (京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.
The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only a determined research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.
The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.

7 . Zea Tongeman, a 14-year-old student, who is crazy about the Internet, applied technology to create an application that encourages people to recycle while having fun.
Zea was really inspired when she attended “Little Miss Geek Day”, an event that aims at making technology more accessible and appealing to young women and inspiring them to consider technology careers. Soon after, she entered “Apps for Good”, a competition that encourages students to create positive change through technology. Teaming up with her friend, Jordan Stirbu, she laid the foundations for “Jazzy Recycling”.
The “Jazzy Recycling” application is designed to encourage young people to recycle more, which wins the favor of the youth. It turns waste disposal into a game and helps you find places to recycle. Then you scan what you need to recycle, share it, and get rewards such as shopping vouchers (代金券) and games to be unlocked for what you have recycled.
Tapping into the teen enthusiasm for sharing every little aspect of their daily life on social media like Facebook, Twitter or Instagram, recycling efforts can be shared too as a fun game among friends, which makes more people take part in recycling activities.
Zea explains why she is addicted to the Internet and how technology has changed her ideas about the future, “I used to think technology was just fixing computers and using smartphones; I have become very tired from just using what is available. I have discovered another side to it and that I can make technology of my own.”
In fact, Zea Tongeman has taken the idea of recycling seriously and hopes all her fellow beings would give it a serious thought. This teen girl from the United Kingdom has made use of computer programming to create her own app that would encourage people to go recycling for a better world.

8 . Microplastics are “one of the greatest man-made disasters of our time”, according to the Natural History Museum. That’s bad news, given they are also everywhere: in tap water, the food you buy, the clothes you wear and the air you breathe.
The largest microplastics can be seen by the naked eye and are anything under half a cen- timetre in size. But many of them are small enough to act like spots of dust which we can unconsciously breathe in or eat in food. The smallest particles are called nanoplastics and they are small enough to get their way deep into the human body.
New findings from the University of Portsmouth show that there is so much synthetic material in our homes that we might be breathing in up to 7, 000 microplastic particles a day. Using special equipment, researchers measured a typical family home and found the highest concentration of it was in the bedroom of the eight-year-old daughter, whose room was decorated with plastic-based bedding, carpet and soft toys.
Although research is in its early stage, the risks of these plastics could be serious—some studies have linked high exposure to cancer risk and disrupting our hormones. In animal studies, the particles have been shown to affect metabolism, gut bacteria and the immune system, among other things.
It is not yet known what a healthy level of microplastics might look like, but Dr Sabine Donnai, CEO of the Viavi clinic, thinks that many people in the West are over the limit. In tests at her clinic, patients often come back with dangerously high levels of plastic in their bodies, she says.

10 . More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers. Qinghai Lake is also the country's biggest saltwater lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point--Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise(天堂) for different kinds of groups of birds and have been called"Bird Islands".
Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake.
To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997. Meanwhile, the State has pointed out the Bird Islands and Spring bay of the Qinghai Lake as central protection zones.
Inspection(视察) officials and management employees often patrol（巡逻） the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous(食肉的) animals, as well as illegal hunters from breaking up the birds’nest building,egglaying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding.
