The Living Planet Index (LPI), which measures trends in thousands of vertebrate species populations, shows a decline of 52% betw
een 1970 and 2010. Biodiversity is declining in both temperate and tropical regions, but the decline appears to be greater in the tropics. According to the World Wildlife Federation (WWF) population sizes of terrestrial vertebrate species have halved over the last 40 years. Along with hunting, ______________ is the major cause of the decrease in the terrestrial vertebrates throughout the world.
A) air pollution B) habitat change C) climate change D) invasive species
The world's biodiversity is declining at an alarming rate. Population sizes of vertebrate species measured by the Living Planet Index (LPI) have ... The LPI, which measures trends in thousands of populations of mammals, birds, reptiles, ... Populations of terrestrial species declined by 38 per cent between 1970 and 2012.
Habitat destruction (along with hunting and fishing) stands out among the factors that trigger biodiversity depletion. Usually this process occurs as a result of urbanization and deforestation to increase agricultural areas and development of major works. In addition, this destruction is also caused by global warming.
As their habitat is destroyed, many species are often forced to migrate to other areas, facing dangers and uncertainty of survival. Those species that are unable to find another place to settle, such as plants, have their population reduced or even often extinct.
This is an example of acquired mutation in which there is genetic transformation due to external factors such a change of temperature, pollution, radiation etc.
