Humans use electricity to light up the night sky. But did you know that nature itself can glow, too?

    {#blank#}1{#/blank#}. Some use their lights to communicate. Others shine to hunt, to mate or to protect themselves. The vampire squid, for example, gives out a cloud of light to scare enemies.

    {#blank#}2{#/blank#}.

    In 2013, the US company Gleaux said it had created the world's first light-producing plant, reported the Daily Mail.

    {#blank#}3{#/blank#}.

    “People have dreamed about this stuff for many years,” said Alexander Krichevsky, the company's founder.

    He and other researchers are working toward a future in which glowing plants replace lamps and glowing trees line highways.{#blank#}4{#/blank#}, making them glow to let farmers know when they need water or are ready to be picked.

    While GleauX is working on glowing plants, the French company Glowee is trying to use glowing bacteria to light up shop windows and street signs. It is the same type of bacteria that causes certain sea animals to light up.

    {#blank#}5{#/blank#}.The company is now working on a light that shines brighter, lasts longer and comes in different colors.

    “Our goal is to change the way we produce and use light,” said Glowee founder Sandra Rey. “We want to offer a global solution that will reduce the 19 percent of electricity consumption used to produce light.”

A. People are also creating glowing bacterial art that you can hang in your home

B. Scientists have found many glowing creatures, most of which live in the ocean

C. Krichevsky also hopes the technology could be used in crops

D. Researchers around the world are looking into nature's lights for new ideas

E. It is a genetically-modified plant that glows like fireflies do

F. In 2016, Glowee created a bacteria-powered light that glows for three days

G. This technology could help us save much energy
