The Green Revolution, or the Third Agricultural Revolution, was a period of technology transfer initiatives that saw greatly increased crop yields. [ 1 ] [ 2 ] These changes in agriculture began in developed countries in the early 20th century and spread globally until the late 1980s. [ 3 ]
One of the issues facing biodiversity in areas of industrial agriculture is the loss of heterogeneity, described by the loss of a biotic and abiotic diversity. [1] [3] Since 1966, the Green Revolution enhanced agricultural productivity through technological, economical, and political advancements in an effort to increase food security globally. [14]
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.

Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [ 41 ] and some species are now only breeding in modified habitat. [ 42 ]
Deforestation, pollution, and biodiversity loss are only among a few causes. “Since the Industrial Revolution , we have been putting pressure on nature by using its resources without supporting ...
Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics. It is a subset of a specific element of agricultural biodiversity .
Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries.. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself [1] [2]), with an ...
