Use of Non-human Primates as Labour

The issue

The intelligence and manual dexterity of many non-human primates has resulted in their exploitation as 'workers' in different settings. Denied their freedom, these animals are usually deprived of the companionship of other non-human primates and forced to take part in unnatural activities purely to benefit people.

'Helping' hands: Monkeys, particularly capuchins, are 'trained' to help disabled people with various tasks [§]. In virtually all cases, the monkey is deprived of not only a natural environment, but also the companionship of others of their kind. In some cases, as often happens with captive non-human primates, the monkeys will become a danger to the person [§]. The American Veterinary Medical Association, the largest veterinary medical organisation worldwide, is opposed to the use of non-human primates as 'service' or assistance animals because of welfare and public health concerns (AVMA 2022).

'Waiters: Japanese macaques (Macaca fuscata) are used as 'waiters' as a means of attracting customers in Japan [§; §]. The monkeys are forced to wear costumes, such as a waiter's shirt and skirt, and serve beer to guests and carry out other tasks. The animals are forced to walk on their hind legs. This 'bipedal walking' is normally used by these macaques over short distances. Forced, continuous locomotion in this manner, however, is not natural and might lead to joint and muscle damage.

Picking coconuts: Macaques, northern pig-tailed Macaca leonina) or southern pig-tailed (Macaca nemestrina), are used to 'pick' coconuts in Malaysia and Thailand [§; §]. The macaques appear to be largely wild-caught [§; §]. An investigation carried out in 2020, exposed the mistreatment and abuse of captive pig-tailed macaques, kept chained in terrible conditions and forced to climb trees and pick coconuts. Another study demonstrated the welfare of the macaques was not good [§]. The public are not supportive of using monkeys to pick coconuts [§].

Detonating landmines: The government of Morocco purportedly had trained monkeys, possibly Barbary macaques (Macaca sylvanus), to detonate landmines [§]. It was reported that Morocco offered the US forces a large number of these monkeys, to use them for detonating land mines planted by the Iraqis.

Way forward

The severe deprivation and cruelty towards the monkeys is untenable. In all these situations, other than detonating land mines, the obvious alternative is to utilise the services of people. It is widely known that unemployment is a major worldwide issue for people, resulting in severe poverty. Rather than exploit and inflict suffering on non-human primates, it would be far better, even if one's interest was just people, to provide jobs in the various service fields.

Other alternatives for providing care for disabled individuals include sophisticated mechanical devices such as the care-providing robotic system FRIEND (Functional Robot arm with user-frIENdly interface for Disabled people), a semi-autonomous robot designed to support disabled and elderly people in their daily life activities [§].

There are alternatives to using non-human primates (and other non-human animals) for finding and neutralising landmines, such as mechanical mine clearing machines [§].

  10. But humans are exceptionally skilled at putting their needs first over other animals'. With these primate cousins of ours, we alter their lives with a firm eye on human benefits and a reluctance to consider the cost to the capuchins themselves. The greater kindness is to allow monkeys to live their lives as monkeys.
