Natural Causes:
* Old Age: Like humans, monkeys have a natural lifespan, and they can die of old age due to organ failure or general decline.
* Disease: Monkeys are susceptible to a range of diseases, both infectious and non-infectious. Some common diseases include tuberculosis, malaria, and parasites.
* Predation: Depending on the species and location, monkeys can be prey to predators like leopards, snakes, and eagles.
Human-Related Causes:
* Habitat Loss: As human populations expand, they encroach on monkey habitats, leading to loss of food and shelter, making them more vulnerable to disease and predation.
* Hunting and Poaching: Some monkeys are hunted for their meat or for the illegal pet trade.
* Disease Transmission: Humans can transmit diseases to monkeys, sometimes with fatal consequences.
* Road Accidents: Monkeys living in close proximity to humans are at risk of being killed by vehicles.
Other Factors:
* Stress: Living in captivity or in environments where they are constantly threatened can cause stress, leading to weakened immune systems and increased vulnerability to disease.
* Accidents: Monkeys can be injured in falls, fights with other monkeys, or by being trapped in man-made structures.
It's important to remember that monkeys are living creatures with complex needs, and their deaths are often a result of a combination of factors.
