The Orangutans: The Sustainable Palm Oil Industry

Decent Essays

The orangutan, one of the world’s great apes, resides on the Indonesian islands of Sumatra and Borneo. The forests of these islands are being destroyed in order to create palm oil plantations. Palm oil is in high demand due to its uses as a biofuel and as a vegetable oil. The palm oil industry is a major threat to the survival of the critically endangered orangutans, due to loss of habitat. This leads to illegal poaching since the orangutans are viewed as pests, leaving many young infants orphaned and alone. There are rescue groups that rehabilitate these great apes, but more must be done in order to prevent the extinction of this rapidly declining species. Sustainable palm oil options need to be researched and utilized and there should …show more content…

Orangutans have long lifespans (30-40 years) with long interbirth intervals and low reproductive rates. In fact, females have eight year intervals between births and will only give birth to one or two offspring in her lifetime. The reason why this poses a problem is that when an enormous amount of orangutans are killed, it’s tough to recover because they are not producing large numbers of children nor do they have short interbirth intervals. Consequently, there will be extremely high death rates and very few births (UNEP, 2007). Their population numbers will continue to fall because they won’t be able to compensate for the great loss. A study completed by Michael Bruford and Benoit Goossens at Cardiff University showed that in 1900, there were approximately 315,000 orangutans in Indonesia. Currently, there are about 60,000 orangutans living in the forests of Indonesia, which is a massive population decline (Kaye, 2016).When orangutans are driven out of their habitat due to deforestation and illegal logging it forces them to roam a great distance in search of food. Orangutans are solitary creatures, spending the majority of their time in the trees. Their diet relies mainly on fruit, with a preference for fruit with soft pulp. They also eat buds, flowers, leaves, soil tree bark, and some insects. Due to their largely frugivorous diet, they have to monitor the seasonal availability of resources. When fruit is abundant, they will increase their food intake and store the food as fat for energy. This enables them to eat low quality food items in habitats where fruit may be scarce (Delgado & Van Schaik, 2000). The dipterocarp forests of Borneo and Sumatra have trees that fruit simultaneously, so there is an abundance of fruit once every 2 to 5 years which are known as the “mast years”. During the other years there is not as much fruit, so orangutans have to maintain large home ranges in
