United Nations Secretary-General Ban Ki-moon called on the international community on Saturday to have "inclusive dialogue and inclusive policies, embracing all different groups of people" when dealing with international terrorism.
Ban made the comments in Nairobi, during a two-day visit to Kenya to attend the first-ever UN Environmental Assembly.
International terrorism ranked high on the assembly's agenda, as illegal timber and products of wildlife crime are smuggled through the same routes as illegal weapons.
"Wildlife has been used as a route of terrorism. Illegal timbering, illegal timber, this poaching. All these routes have been used as a way, these weapons and arms have been used, carried over all these routes, so we need to see in a comprehensive way," Ban said.
The UN Secretary-General also said no country should have to handle counter-terrorism efforts alone.
He was referring in particular to Boko Haram, the Nigerian extremist group that abducted over 200 schoolgirls in April and has repeatedly attacked public locations where large numbers of people gather, in its campaign to impose Islamic law in Nigeria.
A UN special envoy has met twice with Nigerian President Goodluck Jonathan to offer a support to the country.
The assembly in Nairobi was the highest-level UN body ever convened on the environment.
Ban said he hopes to see UN member states adopt a climate change deal during formal talks in Lima in December.
Earlier Saturday, Ban met with Kenyan President Uhuru Kenyatta to discuss ways of strengthening Kenya's security forces.
Also on Saturday, Ban adopted a 6-month-old lion cub.
The young lioness, which was found abandoned in Nairobi National Park, will be raised by the Nairobi Animal Orphanage.
Ban named the lioness Tumaini, which means "hope" in Kiswahili, after his hope that "all people around the world will be able to live harmoniously with nature."
Ban's new lion cub is not the first exotic pet he's received as head of the UN.
In 2009 Mongolia presented Ban with a rare horse named Enkhtaivan, or "Peace," and in 2008 South Sudanese President Salva Kiir gave Ban a white bull named Ban Ki Moo.
