Final answer:
Increased population growth leads to greater land demand for resources, resulting in habitat destruction and deforestation, especially in areas like the Amazon and Southeast Asia. Over-reliance on firewood in rural areas further accelerates the loss of forests. Sustainable alternatives are critical to preventing ecological decline due to unchecked deforestation.
Step-by-step explanation:
Impact of Population Growth on Deforestation
When a population grows, it creates increased demand for land to supply necessary resources such as food, water, and energy. This demand often leads to habitat destruction and the clearing of vegetation. In regions like the Amazon, agricultural expansion for cattle ranching and soy farming takes precedence over the conservation of forests, despite low population densities. Similarly, in parts of Southeast Asia, rapid deforestation is driven by the need to establish plantations for crops like oil palm. In areas with arable land, the pressure from population growth can lead to unsustainable agricultural practices, such as excessive land clearing and shortened fallow periods. As a result, precious natural reserves of biodiversity, like tropical rainforests, are being lost at alarming rates.
Deforestation in rural areas, particularly in developing countries, is also intensified by the reliance on firewood as a primary fuel source. With the limited availability of firewood, communities often resort to cutting down more trees, exacerbating the deforestation problem. The rise in global population directly correlates with increased deforestation, as more people utilize natural resources for survival and economic purposes. If this trend continues without sustainable management, it can lead to ecological decline and a potential crash in human populations.
