According to new research, trees in cities reduce air pollution, absorb carbon, and protect people in heat waves, saving more than $0. 5 billion in health care, energy costs and environmental protection for special cities every year
A New York State University study shows that by 2030, one out of every ten people is expected to live in cities with more than 10 million residents, and urban forests can make these spaces healthier and more affordable (SUNY)said.
Theodore enderney, lead author of the School of Environmental Science and Forestry at New York State University, told the Thomson Reuters Foundation that "greening urban areas is critical . ".
"Trees are essential to human well-being and biodiversity and are the foundation of our quality of life.
Urban forests can reduce the city's "urban heat island effect", the city is several degrees warmer than the nearby rural areas, the air and water pollution deteriorate, and the production capacity of sultry workers decreases, the study said.
Plants cool the surrounding air by evaporation, and their leaves block the heat of the sun and absorb the noise.
During the heat wave, trees cool down buildings as temperatures rise, which may reduce the cost of fans and air conditioners, the study said.
The researchers focused on 10 mega cities around the world, including Beijing, Moscow and Argentina, and found that if more trees were planted in areas such as sidewalks, the benefits of urban forests may increase near squares and parking lots.
But they say urban protection has been ignored and replaced by larger, more remote areas of nature.
"If we focus our efforts outside the city,trees)
Endreny said: "We are being ignored because there are more than 0. 7 billion people in 40 mega cities in the world. (
