While the two most populous countries in the world are often taken for carbon emissions, a new study says China and India have led to an increase in vegetation over the past two decades.
According to a NASA study published Monday in Nature Sustainability, the green expanses of the earth – including plant and tree leaf regions – grew by 5 percent from the early 2000s, and green for two decades equals the area covered by All of the Amazon rainforests – China's aggressive forestry program – 42 percent of the horticulture in China is related to the growing forest area – and India's intensive food crops have led to an increase in the green expanses of the states, while countries such as Brazil and Indonesia have been hit by losses of natural vegetation, H.
"China and India are responsible for one-third of the greening, but contain only 9 percent of the planet's surface covered with vegetation – a surprising finding given the general idea of land degradation in densely populated countries," writes lead author of the study, 39, was quoted as saying in a NASA report.

As China plans to fight the effects of climate change as well as desertification and deforestation, the state has pledged to be estimated at 400 million hectares of forest area under its "Great Green Wall" project initiated in 1978. Jang Jianlong, head of the State Forestry Administration In China, said last year that the country plans to receive 23 percent of the total landmass covered by forests by 2020. To achieve the goal, the administration kicked a few forestry projects – Hebei Province in the Inner Mongolia Inner Autonomous Region, and in North Qinghai Province – to Cover a total of at least 6.6 million hectares, which is almost the size of Ireland.
NASA's satellite images collected between 2000 and 2017 show the northern regions of China's high density of green.The US Space Administration has used a high-resolution data collection device on two satellites for nearly 20 years – capable of capturing vegetation areas up to 500 meters on a ball Country.
However, China's achievements in forestry have also raised concern among experts who say the country "cultivates large plantations with little biological diversity." A study published in 2011 in the journal Earth-Science Reviews also notes that China's large-scale afforestation policy was not adapted to local environmental conditions, and that the introduction of "inappropriate species" could lead to environmental degradation.
