Air pollution is the world's top killer, a new global air quality index revealed last year. According to the World Health Organization(WHO), 4. 2 million people die each year from outdoor air pollution, and 91 percent of the world's population lives in a place that exceeds the WHO's guideline limits. With that in mind, Imperial College London has teamed up with biochemical tech startup Arborea to test out its biosolar leaf technology, while also demonstrating how sustainable solutions can address the vital environmental and social issues of today in real-world conditions.
So, what is a biosolar leaf and how does it work? The secret is algae(海藻). Arborea researchers developed a cultivation(培养)system that allows microscopic plants like microalgae to grow on large solar panel-like structures that can be installed on land, buildings, and anywhere with a roof in a built-up city to improve the surrounding air quality. Inspired by the natural process of photosynthesis(光合作用)，the biosolar panels allow the microorganisms to absorb CO2 from the surrounding area and generate breathable oxygen back out again. And they help produce a nutritious, sustainable plant protein with tiny environmental impact—— Arborea's other focus——at the same time. "When I founded Arborea? my goal was to cope with climate change while addressing the critical issues related to the food system," Arborea founder and CEO Julian Melchiorri said. "This pilot plant will produce sustainable healthy food additives while purifying the air, producing oxygen and removing carbon dioxide from the surrounding environment.”
Melchiorri has already had some success with his astonishing project, the world's first living bionic chandelier(仿生吊灯)，which uses the same technology. The light of the chandelier stimulates photosynthesis of the microorganisms on the leaf-shaped modules, absorbing the CO2 inside and releasing oxygen back into the room. The chandelier currently holds pride of place in London's Victoria and Albert Museum's permanent collection.
1.Why did the Imperial College London cooperate with Arborea?
A.To study the reason for air pollution in London.
B.To search for the new sustainable energy.
C.To trial the new technology of Arborea.
D.To settle the social issues.
2.What can be learned about the biosolar leaf?
A.It functions just like solar panels.
B.It imitates the natural process of photosynthesis.
C.It is aimed at producing sustainable healthy food.
D.It has been applied in large amounts in our daily life.
3.What is the best title for the text?
A.London's pride—the chandelier
B.The secret of algae found recently
C.An astonishing project benefiting Londoners a lot
D.World's first biosolar leaf to take on air pollution
4.Which column of a web page is the text probably taken from?
A.Environment and marine biology. B.Society and development.
C.Science and technology. D.Bionic design and modern life
