India and China are leading the world greening task, a latest NASA study said on Monday. It has found that the world is a greener place than it was 20 years ago. Recent satellite data shows the greening pattern (模式) is very clear in China and India.

Data from NASA Earth satellites shows that human activities in China and India influence the greening of the planet, thanks to tree planting and agriculture. The influence comes mostly from great tree-planting programs in China and modern agriculture in both countries.

China’s great influence on the global greening mainly comes from its programs to keep and make forests larger in size. The goals of the programs are to make less land degradation (退化), less air pollution, and less climate change.

“When the greening of the Earth was first noticed,   we thought it was because of a warmer, wetter climate. Now with the satellite data, we see that humans are also playing an important part,” said Rama Nemani, research scientist at NASA and writer of the study.

“Once people realize there is a problem, they may try to deal with it. In the 1970s and 1980s in India and China, the situation about vegetation (植被) loss was severe. In the 1990s, people realize it, and today things have improved. Humans are very strong．That’s what we see in the satellite data,” adding Neman.

Land areas used to grow crops are comparable in China and India more than 770,000 square miles—and have not changed much since the early 2000s. Yet,   these areas have great increased both their green leaf areas and their food production.

Farming is destroying the planet, but there could be a much more environmentally friendly way to feed ourselves: using renewable energy to turn carbon dioxide into food. “This is becoming a reality,” says Pasi Vainikka at Solar Foods, a company that is building the first commercial-scale factory that will be able to make food directly from CO2.

There can be no doubt that immediate attention to find greener ways to grow food is required. Conventional agriculture, including organic farming, causes damage to the environment in many ways. It requires a lot of land, leading to habitat loss and deforestation. It is also the source of a third of all greenhouse gas emissions and releases other pollutants. It isn’t very efficient, either. Crops typically transform less than 1 percent of light energy into usable biomass (生物量).

Instead, Solar Foods plans to avoid photosynthesis (光合作用) altogether, and grow bacteria that use hydrogen as their source of energy. At the factory, renewable electricity will be used to split water to produce hydrogen and oxygen. The hydrogen will be added to large containers, where the bacteria grow, along with CO2 and ammonia (氨气). The end result will be a yellow powder called Solein.

Solein is made of bacterial cells and is up to 70 percent protein. It can be used as an ingredient in all kinds of foods. “We are aiming at replacing animal-sourced proteins, which we think have the highest environmental impact,” says Vainikka.

Compared with plant crops, Solein will use 100 times less water per kilogram of protein produced, 20 times less land and emit a fifth as much CO2, according to Solar Foods. There are other benefits, too: factories could be situated anywhere in the world and production won’t be affected by weather conditions.

“With Solar Foods and other companies scaling up their systems, this is truly beginning a new era of agriculture,” says Dorian Leger at Connectomix Bio in Germany. “I think these trends are exciting and will help bend the carbon curve as well as lead to improved global food supply security.”
