2 . Keeping animals safe on the road

Roadkill is not a rare sight when driving down most highways and sometimes also on roadways in cities.     1    . A recent study has measured, for the first time, the damage that can be caused to animals in urban areas on China’s fast-developing road network.

    2    . Li Zhongqiu and his team from Nanjing University’s School of Life looked at the problem in cities, where roadkill could have an even larger impact.

They chose Nanjing as the study subject, where there are more than 9,700 kilometers of paved roads. A total of nine roads were chosen for the research, including three national highways.     3    . The researchers then monitored the roads every two weeks over a year. The team recorded a total of 293 individual roadkill cases. Birds made up nearly half the total, making them the most susceptible (易受影响的) group to roadkill.     4    . “This may be owing to the large number of stray (流浪的) cats and dogs in urban areas,” Li said. “Abandoned pets are more likely to wander into traffic.” Also, there are a large number of black birds in East China, and they can be attracted by flies or other insects, leading to further accidents.     5    . This may be owing to the fact that some warm-blooded animals have to go out and search for food during these times when food is hard to find. “Roadkill has resulted in the decline (下降) of urban animal populations and must be taken seriously,” Li said. The researchers also call on policymakers to put forward related traffic rules and animal protection rules, such as speed limits and traffic controls.

3 . For those of us who grew up watching Star Trek, exploring space has been about discovering strange new worlds. And there are plenty of worlds to explore in time, but we still need major technological advancements to reach planets that are light years away.

What we are doing in space today is providing unbelievable benefits right now, right here on Earth. From space, we can monitor, manage and care for our planet. Satellite-based sensors show us the short- and long-term effects of human activity on our environment. Many companies are using their interest in space to help solve problems here, from using hyperspectral imaging(高光谱成像), which enable us to map vegetation(植被) and rain forests, to microsatellites that provide global connectivity for the network of things.

My company, OneWeb, is focusing on what I believe is one of the world’s most important issues: the need for equal access to the Internet. The Internet has become our economic lifeblood. And yet, nearly half of the world’s population doesn’t have Internet access. Space is playing a key role in bridging this digital divide. OneWeb is launching 1,980 satellites to help bring Internet access to people everywhere, and our first production satellites are already flying in space and have shown very high download speeds.

Fiber and cable Internet access technologies already cover most financially viable(可行的) major cities. Similarly, these regions will also be the first to be served with 5G. Poor communities are the last to get connected, and without connectivity, those communities have no chance to lift themselves from poverty. OneWeb’s satellites will reach every community in the world and enable equal access to the Internet for the world’s less developed places.

Fifty years from the day when man first walked on the moon, we are still only approaching the possible. There will be tens of thousands of new satellites, space stations and factories in the coming years to bring advancements in communications, scientific research, monitoring the earth, exploring space and more. This is exciting, but we must take action carefully.
