Diet and lifestyle are also key factors influencing elephants lifespan. The vast majority are overweight in zoos, this could explain the high still-birth rates and why they're dying early. Bigger mothers have bigger calves and more of these are still-born.
Compared to wild elephants used in logging companies, their recorded life expectancy is longer - more than 40 years compared with less than 19 in zoo elephants - this could be put down to their lifestyle; for half the time the Burmese working elephants are allowed to act naturally.
Elephants in the workforce work for no more than six to eight hours a day. For the remaining hours they are set loose in the forest to live like wild elephants, where they can meet and mate with other wild elephants, and have a full elephant life, good exercise and good food.
Zoo elephants have a very monotonous lifestyle, every day is the same for them, living in the same compound, with limited roaming, which makes them more stressed.
Sad. I went to an elephant camp in Chiang Mai once and was a bit upset when I saw elephants in chains. They were trained to do animal tricks and paint pictures with their trunks. Even though I was thrilled to meet them, I was wondering if they were treated well enough by the owners. Really, no one wants to be caged. I had an interesting conversation with a friend on how animals should be treated. He thinks them as just 'animals', I see them as unique 'beings' like us with their own intelligence for survival. Whether or not I am western educated, I still believe in treating all living things with respect.
Think of it this way, all animals feel, whether it's fear or a sense of security to love.
And yes, I admire Steve Irwin for all his work done even though I do think some of it should go amiss.
