[84] According to satellite data, the loss of biomass in EU's forests increased by 69% in the period from 2016 to 2018, compared with the period from 2011 to 2015 ...
Large scale urban reforestation programs in the United States include New York City's Million Tree Initiative [11] and TreePeople in Los Angeles, which planted 1 million trees in preparation for the 1984 Summer Olympics and continued planting thereafter. [1] In 2022, Boston announced a new forestry division to grow the tree canopy within the ...
[25] [26] People living in urban communities with significantly lower percentages of urban trees do not benefit from the same environmental and health impacts as those in communities with greater tree populations. In New York, specifically, the South Bronx has far fewer trees than New York City neighborhoods with higher income levels.

Deforestation, particularly in large swaths of the Amazon, where nearly 20% of the rainforest has been clear cut, has climactic effects and effects on water sources as well as on the soil. [ 32 ] [ 33 ] Moreover, the type of land usage after deforestation also produces varied results.
Drivers of deforestation and forest degradation by region, 2000–2010, from the Food and Agriculture Organization publication The State of the World's Forests 2020. Forests, biodiversity and people – In brief [3] Deforestation is much worse than forest degradation, but it is clear and visible.
3.9 billion people—half of the world's population—currently live in cities globally. It is projected that 5 billion people will live in cities by 2030. [95] Cities across the world occupy just 3 percent of the Earth's land, yet account for 60–80 percent of energy consumption and 75 percent of carbon emissions. There are serious challenges ...
