The International Union for Conservation of Nature found more than one in three tree species worldwide faces extinction. ... The loss of trees is a threat to thousands of plants, fungi and animals ...
The extinction of C 3 plant life is likely to be a long-term decline rather than a sharp drop. It is likely that plant groups will die one by one well before the critical carbon dioxide level is reached. The first plants to disappear will be C 3 herbaceous plants, followed by deciduous forests, evergreen broad-leaf forests, and finally ...
The forest resources of the United States remained relatively constant through the 20th century. [3] The Forest Service reported total forestation as 766,000,000 acres (3,100,000 km 2) in 2012. [4] [5] [3] A 2017 study estimated 3 percent loss of forest between 1992 and 2001. [6]
Its initial target was the planting of one billion trees in 2007. Only one year later in 2008, the campaign's objective was raised to 7 billion trees—a target to be met by the climate change conference that was held in Copenhagen, Denmark in December 2009. Three months before the conference, the 7 billion planted trees mark had been surpassed.
The island of Hispaniola was first colonized by humans 6,000 years ago and the population size was likely more than one million when the European colonists first arrived in 1492. [6] Those original inhabitants used trees and caused extinctions of birds and mammals. [11] [12] Nonetheless, the greatest deforestation occurred after 1492. [8]
This decline in plant life is likely to be a long-term decline rather than a sharp drop. Plant groups will likely die one by one well before the 50 parts per million level is reached. The first plants to disappear will be C 3 herbaceous plants, followed by deciduous forests, evergreen broad-leaf forests and finally evergreen conifers. [81]
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
