Poisons like cyanide can be a deadly weapon for poachers, allowing them to kill dozens of animals without needing access to firearms or the backing of criminal syndicates. Wildlife poisoning is on the rise across Africa, targeting elephants as well as pushing endangered vultures toward extinction. A new study says Zimbabwe, which a decade ago witnessed some of the deadliest mass poisonings of elephants, has developed a sound basis for curbing poisonings by tightening laws to criminalize intent to use poison to kill wildlife. In addition to laws and renewed efforts to improve intelligence gathering, private players are pushing to ensure better law enforcement, resulting in more prosecutions and deterrent sentences.
