From 2 Million to 170,000: Chimps' Alarming Decline
10 Jul
Summary
- Chimpanzees share 98.8% DNA with humans, making them our closest living relatives.
- Jane Goodall first observed tool use in chimps in 1960, challenging human uniqueness.
- Chimpanzee populations have plummeted from millions to an estimated 170,000.
Chimpanzees, our closest living relatives, share approximately 98.8% of our DNA and exhibit complex social behaviors and emotions, including empathy and grief. Their intelligence is further demonstrated by their regular use of tools, a behavior first scientifically documented by Jane Goodall in 1960 in Gombe, Tanzania. This groundbreaking observation challenged the long-held belief that tool-making was exclusive to humans.
Goodall's extensive research, spanning over 65 years and totaling more than 165,000 hours of notes, also revealed that chimpanzees hunt in groups, eat meat, and form close-knit family units. These observations laid the groundwork for ongoing, long-term studies of wild animal behavior.
However, these remarkable primates are facing an unprecedented threat. A century ago, one to two million chimpanzees inhabited 25 African countries. Today, estimates range from 170,000 to 340,000 individuals. All chimpanzee subspecies are endangered, with the western chimpanzee critically endangered, having experienced an 80 percent population drop between 1990 and 2014.
The primary drivers of this alarming decline are deforestation for agriculture and logging, hunting for bushmeat, disease, and the illegal pet trade, which often involves stealing infant chimps. Conservation organizations are working to combat these threats.
Sanctuaries play a vital role in providing a last hope for displaced and rescued chimpanzees. Facilities like the Tacugama Chimpanzee Sanctuary in Sierra Leone and Ngamba Island in Uganda house over 120 and 50 rescued chimps, respectively. These sanctuaries offer long-term care, recognizing that chimpanzees can live for 50 to 60 years.
World Chimpanzee Day, celebrated annually on July 14th in honor of Jane Goodall's arrival in Gombe, serves as a crucial reminder of the urgent need for action. Individuals can contribute by donating to accredited sanctuaries, choosing ethical tour operators when observing wild chimps, and supporting initiatives like the JGI ForeverWild campaign that combat illegal wildlife trade and habitat loss.
