There are two places where you can adopt an animal online:
Research suggests that since the 1970s the numbers of gorillas have decreased from 100,000 to 50,000. They have often been the target of poachers and have fallen victim to Ebola and the effects of deforestation.
You can help preserve them by adopting or sponsoring a gorilla as a gift. 
Western Lowland Gorillas are most often found in Angola, Cameroon, Central African Republic, Congo, Democratic Republic of the Congo, Equatorial Guinea and Gabon. You can sponsor animals like this through the WWF. 
The Fund is dedicated to nurturing and protecting endangered species of animals from all over the world. Their website offers you the opportunity to contribute to the welfare of many different species that desperately need protection. Through its animal adoption and sponsorship scheme it returns endangered animals to safe, natural habitats. Adopt or sponsor an animal today, and help them do their vital work. Adopting an animal in this way is also a creative and worthwhile ethical gift for family or friends whether it be for Christmas, a birthday or even as a creative wedding gift.
