They hug, kiss, play and cry. They even clean each other by having grooming sessions. They have emotions like our own and express them in similar ways. Goodall spoke about the inhumane treatment of the chimps in laboratories and by poachers. The labs keep the chimps locks in small cages, making it impossible for them to move properly.
Poachers kill mothers for their children, and then leave the young chimps tied up to sell.
The children need their mothers to survive. Goodall saw a chimp tied up one day but decided it would not be a good idea to buy it because then the poacher would kill another mother for more children. Instead, she called the authorities because it is illegal to poach. This prompted her to set up a shelter for orphan chimps. Many mistreated chimps are sent to this refuge to live with others.
