With record high temperatures in the western United States, a new report shows that the United States needs to plant more than 30 million trees in major cities across the country to cope with the uneven distribution of trees.
The British “Guardian” reported on the 29th that this is the first time that the United States has conducted statistics on trees nationwide and scored a “tree fairness score” through a number of indicators. The score reflects the US socioeconomic, population density and existing tree coverage Wait for the situation.
Statistics have found that communities inhabited by ethnic minorities are particularly lack of trees, while wealthy white communities are thriving. Communities with predominantly colored people have 33% fewer trees on average than communities with predominantly white people. Compared with communities with poor populations of only 10% or less, communities with more than 90% of the poor population have a 65% lower tree coverage.
It is predicted that by 2060, the tree coverage rate of American cities will decrease by 8.3%. The report stated that if the United States wants to achieve “tree fairness”, a total of approximately 31.4 million trees need to be planted. It is reported that trees can quickly cool the surrounding area through shading and transpiration. In addition, planting trees will also create 228,000 jobs in the United States, and reduce the incidence of respiratory diseases by reducing air pollution, saving nearly $1.6 billion annually.
