This entire endeavour would have to become a long-term process that would last the entire life of the Elephant, which is approximately 70 years.
For the Elephant to be completely protected there would have to be multiple approaches that would include;
Education – A program that educates African Children & Adults about the value of the Elephant in their environment and the absolute necessity of keeping the Animal from any harm during its lifetime.
Security – Additional funding for Game Park Rangers & Volunteers who endeavour to protect the Elephant every single day and night from Poachers. Additional funding for training and state-of-the-art tracking equipment. Decent Salaries, make the Warden's jobs extremely desirable, especially to young adults.
Negotiation – On-going talks with the Government Officials to take immediate and long-term measures to prevent ivory trading in their county and punish Poachers to the full letter of the Law. Also ban regulated Hunting in all forms. Also provide additional funds to move Animals once a region becomes to densely populated, rather than cull the animals needlessly.
Immediate Action – For Elephants that are in immediate danger, humanely remove their tusks. Although perhaps a controversial method, it would undoubtedly make the Elephant a far less appealing target to Poachers.
Entrepreneurship - Poaching is for financial gain. Therefore, perhaps there is an amicable way to eradicate Poaching by creating alternative income solutions for the Poachers, and their families. Additionally, promoting Tourism and other International initiatives to provide solutions to indigenous challenges the Villagers must face on a day-to-day basis. Attract infra-structure funding and job creation solutions, etc.
Marketing – Providing on-line resources for Schools and Colleges. Giving people in first world regions a greater understanding of the African culture and lifestyle. Providing a caring and productive global community that is effective in completely eradicating apathy towards Animal welfare on the Planet.
So, in summary, if we can save the life of just one Elephant, then Five Alive will be a complete success.
