The relationship between deforestation and food security will be one of the major concerns for the coming generation, with the increasing population and spiking rate in resource requirements. Understanding Deforestation: Causes and Impacts. Deforestation is the leading cause of the loss of wild flora and the extinction of several species. Such impacts are particularly pronounced in tropical regions where rapid transformation of rainforest to intensive agriculture (e.g., to oil palm or sugar cane plantations) is occurring. Yet, there is very little research-based evidence of how tropical stream food webs respond to increasing land-use intensification. Furthermore, recent studies

Disruption of Food Chains and Ecosystem Balance. Forest ecosystems are characterized by intricate food webs, where every species plays a critical role. When deforestation occurs, these relationships are disrupted. The loss of key species, such as apex predators or keystone herbivores, can have a cascade of effects throughout the entire food chain. Beyond species extinctions, deforestation also disrupts the intricate food webs that connect different organisms within an ecosystem. The loss of keystone species, those that play a critical role in maintaining the ecosystem's structure and function, can have cascading effects, further destabilizing the environment. 5 ways to stop deforestation in our food Our 10 myths about deforestation 8 things to know about palm oil Bringing our world back to life.

Human activities, including deforestation, urbanization, and pollution, have significant and often detrimental effects on forest food webs, disrupting the delicate balance of energy flow and trophic interactions. The removal of trees and vegetation not only reduces habitat availability for various species but also alters energy pathways within Deforestation, driven by agricultural expansion, mining, and logging, exacerbates food insecurity. According to Global Canopy, in Indonesia, palm oil production is a leading cause of deforestation. All five of the nodes are effects and causes of each other - that is, a loss of biodiversity causes food insecurity, which leads to more deforestation, which leads to greater CO2 emissions, and so on. For example, if current deforestation rates continue throughout the years, the Amazon's soy production could fall by 25% by 2050.
