1 Just when I start to worry aboutthe fate of the world， along comes anew generation of innovators who aremaking big changes in the way thingsare done.

Nikita Rafikov

2 Nikita is young， but he has bigplans for the future， and he has the ideas to get him there. The 11?year?old developed a wayto embed（嵌入） Green Fluorescent Proteins（GFP） into windows to create efficientlighting. GFP is the protein found in certain jellyfish that creates those coolbioluminescence （ 生物發(fā)光） effects seen in nature photography. By embedding thisprotein into windows， Rafikov has found a way to light homes without the use of electricity.

Lynnae Shuck

3 After a positive volunteer experience at a nearby wildlife refuge， Lynnae wanted tofind a way to teach more kids the role of refuges and give them more opportunities to helppreserve them. So she carried out the Junior Refuge Ranger program where kids aged 8 to11 participate in labs， habitat hikes， and birding expeditions to learn about conservation，endangered species protection， habitat restoration， and environmental awareness.

David Cohen

4 David Cohens big idea is the perfect example of how creative kids can be when theyare allowed to think outside the box. Cohen was learning about earthworms in scienceclass when he wanted to build a robotic earthworm， after which he wrote the codebehind a prototype robot. By loading the robot with heat?sensing technology， GPS， andother life?saving programs， Cohens robot could be used to find and rescue people safelyand efficiently.

Jai Kumar

5 Jai likes to invent things， especially things that provide simple solutions to everydayproblems. The 12?year?old middle?schooler has created a gaming system for the senior aswell as an automatic light dimmer（自動(dòng)變光裝置）that senses sound levels in the schoolcafeteria. But what landed him on this list of eco ? innovators is his window ? mountedsolar?powered air filtration device designed for developing countries where air pollution isvery high. The device uses inexpensive components to purify the air before it enters thehouses.
