The most beautiful and intelligent animal: African Elephant

Most contemporary ethologists view the elephant as one of the world's most intelligent animals. Elephant brains are similar to humans. Elephants are known to incur post-traumatic stress syndrome following a serious trauma (Bradshaw et al., 2005). The four elephants at Warsaw Zoological Garden become three in March after the death of Erna, which left one of the herd, Fredzia, a young female African elephant, 

particularly distressed. 

The three African elephants at the zoo will be given liquid doses of a high concentration of cannabidiol or CBD, the chemical compound found in marijuana plants known to have relaxing effects.
