3 . It is late autumn—millions of gardeners across the northern hemisphere, pulled on their thickest sweaters, spent hours clearing large piles of leaves and packed them into plastic bags at the end of driveways.
In the US alone, nearly 10 million tonnes of garden waste go to landfill every year. That is a large amount of effort, not just from an environmental viewpoint but from that of our aching backs, too. So where does this advice come from? Well, it largely comes from the belief that thick fallen leaves can make plants under them unable to breathe, especially shorter grass. They shut down important photosynthesis (光合作用) and get in the way of the growth of the shorter grass. However, this received wisdom has recently been questioned by researchers at Wisconsin University.
The key finding of their new research was that although clearing fallen leaves is one of the most common gardening practices, it makes very little sense. In natural ecosystems, fallen leaves help return nutrients necessary for healthy plant growth to the soil, which greatly improves soil condition. Removing leaves year after year breaks this ecological (生态的) balance. Letting some leaves stick around to cover your garden is a great way to help your grass and the local ecosystem.
They further explained that if up to 50percent of your grass lawn (草坪) is covered by fallen leaves, you might as well go back indoors and put your feet up. The advantages of this light leaf coverage far outweigh the disadvantages—the leaves will quickly break down and help next year’s lawn grow far better than if you had cleared them. Only at over 50 percent coverage do the Wisconsin researchers recommend clearing.
So why not consider leaving the leaves? Save time, carbon and effort, and in exchange get a healthier lawn from this garden waste—that seems like a pretty good deal. And how many plastic bags could be saved by simply not binning fallen leaves every year? In the US alone, about 700 million.

9 . Having been born along the shores of Lake Victoria, the largest lake in Africa, Rahmina Paulette said she has witnessed firsthand the effects of climate change leading to great difficulties like drought and floods.
The 15-year-old Kenyan teenager said East Africa is highly dependent on Lake Victoria, but high pollution has led to poisoning of the water, soil erosion and health problems in people living around the lake.
As Paulette grew older, she realized she was slowly turning from being a witness to a victim of lake degradation. So, she decided to take action and save the lake in her own little way.
“Being an Indigenous person from Lake Victoria, I would like to help restore the ecosystem for my community that has an ancestral connection to the lake and also for the future generations to enjoy the cool breeze, good smells and see the biodiversity within Lake Victoria,” Paulette said.
In her efforts to end pollution in the lake, Paulette started an environmental organization called Kisumu Environmental Champions.
The young environmental champions carry out their activities during the weekends, and the group focuses on environmental conservation, climate change awareness and wildlife conservation.
The group, with about 200 members so far, has taken up the removal of the invasive plant hyacinth from the lake to make eco-friendly products. This project has earned Paulette international recognition. The group has made furniture, paper, cards, folders, document holders, bags and carton boxes from the water hyacinth.
With help from her mother, Paulette is trying to increase activities as she urges all Kenyans to incorporate eco-friendly ways in their day-to-day lives.
Apart from activists like Paulette, other organizations are casting the net wider in their attempt to save the lake. One such group is nonprofit Osienala in western Kenya. The organization has been cooperating with international partners such as those from China to save Lake Victoria.

10 . An augmented-reality (增强现实的) helmet that gives cyclists a 360-degree view of the road could help prevent accidents.
Unlike cars, bicycles don't come with rear view mirrors (后视镜), which is why British product design firm DCA created the Optic helmet. The helmet has front and rear cameras and a drop-down visor (面罩) that can display road conditions in real-time from the rear camera onto a rider's field of view. The visor can show warnings. If a vehicle is overtaking (超过) the rider, it can warn the rider by combining data from the cameras on the front and back of the helmet. In addition, the Optic helmet can provide GPS navigation information for riders who want to track their performance. The design is now just a concept, but it won the “Best of the Best” Red Dot Design Award recently.
Richard Price, a designer at DCA and the brains behind the project, said the helmet is aimed at reducing cycling accidents. Because the helmet is just a concept design, some of the details have yet to be decided, such as the exact method for projecting video onto the visor. However, Price said Google Glass has already shown that this is practical. The Optic helmet will be able to connect to a smartphone via Bluetooth to allow maps and routing information to be updated, but actual navigation will be carried out by the helmet using its onboard (自身携带的) GPS unit. It can be controlled either by a touchpad next to the visor or by using gestures picked up by the front camera.
“Users can order what is shown in the visor to suit their needs and to make sure the display doesn't distract them.” Price said. Since the designs were made public, Price said the design firm has received plenty of positive feedback from cyclists and cycling companies. But actually, putting the device into production will require lots of money, so it is unclear when or if the helmet will be available to consumers.
