If you’re looking for a reason to worry about the loss of trees, this summer’s record-breaking heat waves may be. Trees can drop summer summer temperatures by as much as 10 degrees Fahrenheit, according to a recent study.
But the tree cover in American cities is shrinking. A study published last year by the U.S. Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. That is a decrease of 1% from 2009 to 2014.
Continuing along this path, “cities will become warmer, polluted, and generally unhealthy for residents,” said David Nowak, a senior scientist at the U.S. Forest Service and co-author of the study.
Nowak says there are many reasons our tree branch is declining, including hurricanes, tornadoes, fires, insects, and diseases. But the only reason for the loss of trees that humans can control is a sensible development.
More than 80% of the U.S. population lives in urban areas, and most Americans live in wooded areas along the east and west coasts, Nowak says.
“Every time we put down a road, put down a building and cut down a tree or add a tree, it has consequences not only for that location, but also for the region.”
The study valued the loss of trees based on the role of trees in removing air pollution and energy savings.
The lost value was $ 96 million a year.
