In September 2019, the Plant-for-the-Planet app was released under an open-source license. It allowed users to register planted trees or to plant trees by donating to different tree-planting organizations around the world. [24] The foundation does not take any commissions for donations made through the campaign. [25]
The Columbian exchange of crop plants, livestock, and diseases in both directions between the Old World and the New World. In 1972, Alfred W. Crosby, an American historian at the University of Texas at Austin, published the book The Columbian Exchange, [2] thus coining the term. [1]
New World crops are those crops, food and otherwise, that are native to the New World (mostly the Americas) and were not found in the Old World before 1492 AD. Many of these crops are now grown around the world and have often become an integral part of the cuisine of various cultures in the Old World.
The number of threatened trees is more than double the number of threatened birds, mammals, reptiles and amphibians. The loss of trees is a threat to thousands of plants, fungi and animals ...
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]
Plants with more than one significant human use may be listed in multiple categories. Plants are considered domesticated when their life cycle , behavior , or appearance has been significantly altered as a result of being under artificial selection by humans for multiple generations (see the main article on domestication for more information).
One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...
Living Carbon, an American biotechnology company founded in 2019, has developed genetically engineered hybrid poplar trees aimed at enhancing carbon sequestration. These trees have been modified to improve photosynthetic efficiency, enabling them to capture more carbon dioxide (CO₂) and produce greater woody biomass than conventional trees.
