"Large areas of tropical lowland forests have been replaced by oil palm plantations, with major impact on environment and people. An interdisciplinary team of scientists has now performed a complete and multidisciplinary assessment of all ecosystem functions in oil palm plantations as compared to lowland forests. They found that in oil palm plantations, eleven out of 14 ecosystem functions showed a net decrease, some with an irreversible global impact. The results also reveal mitigation options that can reduce damage and benefit multiple ecosystem functions simultaneously." (Helmholtz) "While the general result was anticipated, our review revealed a breadth of environmental and societal detrimental impact, from local to global scales," (Dr. Kerstin Wiegand )
These palm plantations are ruining the ecosystems which include the life that resides there but also the resources that can no longer be provider from there. it hurts the population in general. This large forest clearing is causing majorly negative effects: it messes with the function of the wildlife and also the soil, air, water, etc.
