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
Within these small groups, the Cross River Gorilla has very predominant traits to keep them alive when almost extinct and facing a harsh environment (What’s Our Mission). These gorillas have a considerably large body size and they also have quite large hands but short forearms; along with small forward facing eyes that are put close together on top of a large nasal region (Etiendem, D., & Tagg, N,). Due to being so big they need a lot of nutrients, and in order to obtain enough food, they eat a large array of diets such as plants in many varieties, and fruits (Etiendem, D., & Tagg, N.). Since they live in the higher parts of the mountains near the border of Nigeria, the amount of fruit trees that exist are much lower than other regions, so they have come to rely on vegetation (Etiendem, D., & Tagg, N.). Since almost all fruit is seasonal, the primates must learn when they can eat one type, and when vegetation is important. (Etiendem, D., & Tagg, N.), (Imong, I., & Robbins, M.). The food they eat also determines how sexually successful they will be in the coming years.
I primarily observed three orangutans, one male, one female, and one juvenile, of Sumatran and Bornean descent, scientifically known as Pongo abelli and Pongo pygmaeus, respectively, and to a lesser extent, two gibbons known as siamangs, or Symphalangus syndactylus. These primates share the same enclosure in the San Diego Zoo in California. I observed the orangutans from 12:58 P.M. to 2:00 P.M. CST on September 19th. During this time frame, the three orangutans mainly stayed high up in their man-made structures, consisting of multiple metal bars covered with nets, ropes, and hammocks. The female and juvenile orangutans stayed above ground from 12:58 P.M. to 1:31 P.M., and again from 1:48 P.M. until 2:00 P.M, approximately 45 minutes. During
Today I’ll be comparing the Narration of “The Cask of Amontillado” and “The Black Cat” by Edgar Allen Poe. Edgar Allen Poe is the author of many great pieces of literature, using his narrators to explain situations that are going on in their life. The narrators of "The Cask of Amontillado" and "The Black Cat" both lead characters love for man’s inhumanity to man and animals through horrific murders.
My observation of the orangutan habitat was on a sunny and hot day with the average temperature being between 65-70F. The Enclosure for the orangutans was a grassy and dirt area that was approximately 35ft+ in width and about 75ft+ in length with a long glass barrier for observation. The habitat featured three 15ft tall fake trees which were fashioned after a tree but bare of leaves. The trees were
The rare Daintree Rainforest is one of the forest that has been demolishing slowly because of logging. With this ecosystem fragmentation is occurring (“All about carbon dioxide”). Ecosystem fragmentation is where the forest is separated into smaller pieces over time because of human activity (“The Daintree Rainforest Australia”). With this happening, animals habitats are becoming even smaller (“All about carbon dioxide”). With more habitat space becoming less it is causing more animals to become threatened and an endangered species (“Deforestation”). Smaller amount of habitat is also affecting the animals migration patterns, their ability to collect food, and provides less shelter (“All about carbon dioxide”). This fragmentation also makes it a struggle for animals to move from one part of the rainforest to another and it also affects the limit it has on the animals breeding population. The ecosystem fragmentation is making them become more vulnerable to extinction (“Population in Daintree”). Logging is cutting down one and one-half acres of trees each second and eighteen million acres of forest are destroyed each year. It is estimated that in over the next quarter of a century up to twenty-eight thousand animal species may become extinct all because of logging and human damned for lumber (“All about carbon
There are many examples of iconic animals that we take for granted when it comes to thoughts of sharing our earth with them in the far future, but it is becoming more evident throughout the passing of time that this will no longer be true with current conditions. When it comes to animals becoming extinct not many people think that many recognized animals, besides the most talked about ones like Polar bears and Giant pandas, are at risk. One of these incredibly recognized endangered animals is the Orangutan. One of the most distinguished of the great apes, both of the subspecies of Orangutan are endangered; The Bornean and the Sumatran, with the Sumatran being declared as a critical species.
Habit loss has been one of the most prominent issues regarding the animal kingdom, and now it seems like the human race is trying to rid our earth of the decreasing amount of flora in certain areas. In Indonesia rain forests are being torn apart to make way for palm oil plantations. Although palm oil is used in packages foods and cosmetics, the Sumatrans elephants and orangutan are suffering from the habitats loss. (Corwin, 8)
“The role of humans in the deforestation of the world's forests is considerable and extensive.” Says Rhett Butler. Humans affect the rainforest many inadequate ways, such as deforestation, and wildfires. Deforestation
Because orangutans are so well adapted for the ecological niche they occupy, it is understandable why their populations suffer when their habitat is destroyed. In fact, in the last 20 years orangutans have lost nearly 80% of their natural habitat largely due to deforestation. Between the years of 1999 and 2006 roughly 55% of that deforestation was due to the expansion of the palm oil industry. Furthermore, Indonesia and Malaysia combined account for nearly 87% of the global output of palm oil with Indonesia generating about 18.7 and Malaysia 17.4 million tons a year. When considering these statistics, it raises questions about why this industry is seemingly more relevant than conserving natural resources and more importantly protecting an invaluable species of ape from extinction. To answer this question, it might be helpful to consider how the vast majority views the palm oil industry by comparison to the orangutans in terms of economics.
The Sumatran Orangutans are mostly located in the trees of the tropical rainforest. They weight from 66 pounds to 198 pounds and can be 4 to 5 feet in length. Their scientific name is Pongo abelii. Unfortunately due to deforestation and other factors the Sumatran orangutans are labeled as critically endangered. Over the years due to habitat loss, the orangutans are losing their homes. The trees from the forests are being cut down and animals like the orangutans who do not come down from their tree are left without a home. The continuation of cutting the trees are leaving more and more Sumatran Orangutans homeless. Also, illegal trade causes the orangutans to be captured and sold. During the process of capturing an orangutans, the mother is
A bad credit score can be really detrimental to anyone, but it can be particularly harmful to potential homebuyers. Credit scores range from 300 to 850, and the higher the better. Your credit score is a calculation of a variety of things such as:
Palm oil is a vegetable oil high in saturated fats extracted from the palm fruit, the palm tree is a native plant to West Africa then was imported into South East Asia in the mid-19th century. It is one of the most popular edible oils and is being used in approximately 50% of products currently in the supermarkets of Australia including cosmetics, toiletries and food. Malaysia and Indonesia grows around 87% of palm oil while Australia imports about 130,000 tonnes of palm oil every year. Due to the oil plantations being in countries where there
I would utilize the natural habitat of Santa Rosa National Park, Costa Rica where the previous study had been done by Hiramatsu et al. At a variety of levels I would suspend even amounts of fruit baskets. Each basket would contain a different fruit and be replenished daily. One would have a favorite fruit of many local primate species, there would be a basket specifically filled with a fruit favorited by each individual primate species, and there would be a basket full of natural but non-native fruits. I would include both ripe and unripe fruit. Over a four month period, two in the wet season and two in the dry season, I would document which species came to which basket, how many foraged in each basket each day, and their behaviors during foraging. For behaviors I would look at sight, smell, competition: hoarding, guarding, stealing, etc. for each fruit basket. I would also document how many fruits each species was willing to eat. Knowing which species are specialist is important conservation data even though it would not apply directly to my study. When analyzing my data I would only look at adults and use the most effective biostatistics analysis available to me at the time of the
Agriculture is the leading cause of deforestation because as human population grows the need for agricultural products increases. Unfortunately, the land used for cultivation results in the displacement of tree reliant animals such as the orangutan. “Without forests, orangutans cannot survive” (Galdikas). Palm oil is produced from trees grown in large plantations in regions where tropical rainforests once existed. The orangutans’ way of life revolves around the existence of trees, they nest in trees, drink water out of holes, and eat their fruit. Orangutans also
Palm oil harvest often leads to deforestation of the rainforests, and raises many ethical concerns from the public, (Levitt, 2015).
