Answer 2

Answer:

C. Human settlement

Explanation:

The main threats to the survival of the species can be divided into two categories: natural and those resulting from the impact on ecosystems caused by humans. Natural hazards lie mainly in climatic changes, such as global changes in the atmosphere (although at present, scientific research has shown that the impact of human activities contribute substantially to global warming, due to greenhouse gas emissions), natural catastrophes such as torrential rains, volcanic eruptions, natural fires and predation by herbivorous animals. The same processes of natural selection also contribute to the disappearance of the species. On the other hand, within the category of the main threats produced by various human activities such as agriculture, the fires provoked, the immoderate felling and in general, the excessive demographic growth; are habitat fragmentation, deforestation, soil loss or degradation and desertification.
