Final answer:
Habitat fragmentation is a major cause of extinction due to habitat loss, which is primarily driven by human activities such as agriculture and urbanization, leading to a decline in biodiversity.
Step-by-step explanation:
The statement that habitat fragmentation is the major cause of extinction is true. Habitat loss, much of which is due to human activities such as agriculture, forestry, mining, and urbanization, is the single biggest cause of extinction worldwide. This not only includes the complete destruction of habitats but also their fragmentation into smaller pieces, which can no longer support the original biodiversity. Habitat destruction affects numerous species, particularly in the tropics where the intensive agriculture and industrial activities driven by globalization are prominent causes.
Agriculture is the leading cause of habitat destruction globally, with other human activities contributing to this critical issue. The loss and fragmentation of habitat lead to biodiversity loss, affecting all forms of life, including plant and animal populations. As natural habitats are replaced or fragmented, many species are unable to adapt to these changes, which can result in their extinction.
