However, a recent national study, conducted by the United States Forestry Service and the Davey Institute, is likely to change that. Given that Los Angeles is bathed in…Details
Some of the most important benefits that trees provide to humans are psychological or emotional in nature. While countless authors, arborists and philosophers have mused that trees help to clear the mind and invigorate the soul, it is important to realize that these claims are not merely conjecture. Scientists have collected plenty of evidence that…Details
