Biodiversity loss happens when plant or animal species disappear completely from Earth or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
The authors have coined the expression "dead species walking" for the more than 500,000 species that are not yet extinct but, due to changes in, or reduction of, their habitats, have no chance of long-term survival.

Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers .
The growing demand for meat is contributing to significant biodiversity loss as it is a significant driver of deforestation and habitat destruction; species-rich habitats, such as significant portions of the Amazon region, are being converted to agriculture for meat production.
Habitat loss, which can occur through the process of habitat fragmentation, is considered to be the greatest threat to species. [14] But, the effect of the configuration of habitat patches within the landscape, independent of the effect of the amount of habitat within the landscape (referred to as fragmentation per se [ 5 ] ), has been ...
Per capita CO 2 emissions from deforestation for food production Illegal "slash-and-burn" practice in Madagascar, 2010 Mean annual carbon loss from tropical deforestation. [149] Deforestation is a major contributor to climate change. [150] [151] [152] It is often cited as one of the major causes of the enhanced greenhouse effect.
Loss of biodiversity: This is the decline in the number and variety of plant and animal species. Loss of biodiversity can have a number of negative impacts, including the disruption of food chains and the loss of ecosystem services. Land conversion can also have a number of negative economic impacts, [27] including:
Human activity, such as fishing, mining, deforestation, etc., serves as a threat for coral reefs by affecting the niche of the coral reefs. For example, there is a demonstrated correlation between a loss in diversity of coral reefs by 30-60% and human activity such as sewage and/or industrial pollution. [41
