Understanding Deforestation's Effects

Listen to the following lecture about the effects of deforestation on global biodiversity:

Professor: Good afternoon, class! Today, we’re going to explore how deforestation is not only affecting individual species but also the entire ecosystems where they reside. To begin, we must understand that deforestation leads to habitat loss, which is one of the primary drivers of species extinction. For instance, a significant reduction in rainforest areas has seen the disappearance of countless species of plants and animals native to those environments. Additionally, the fragmentation of habitats that occurs when trees are cut down can impede the movement of species, which is crucial for reproduction and finding food. Furthermore, the removal of trees is linked to changes in local and global climates. As forests play an important role in carbon sequestration, deforestation contributes to increased levels of carbon dioxide in the atmosphere, leading to climate change. This, in turn, affects the survival of many species adapted to specific climate conditions. Finally, I also want to focus on the socio-economic impacts; local communities often depend on forests for their livelihoods. When these environments are destroyed, not only do species suffer, but human populations also face challenges to their sustainability.
