|Elephants killed for their ivory|
Elephants are being killed again, ivory is on the move, and many elephant populations are in free-fall decline once more. Estimates are that as many as 38,000 elephants were poached in 2006 alone (Scientific American, July 2009 (2.59 MB), a number representing 8% of Africa' remaining elephants killed in one year. This figure far exeeds the elephants annual reproductive rate and even exceeds the poaching rate that existed in the late 1980s, before the 1989 ban took effect. Some scientists believe that if the poaching and trade are not brought under control most populations of elephants could face extinction by 2020.
Historically trade and capture responsible for elephant's demise
Since the Proboscidea originated 60 million years ago, the order has included some 10 families, 45 genera and 185 species and subspecies, in a spectacular diversity of forms. The African (Loxodonta africana and Loxodonta cyclotis) and Asian elephants (Elephas maximus) existing today are the sole remnants of that remarkable evolutionary radiation. Representing a tiny fraction of their former numbers, the living elephants survive in only small pockets of the land they once roamed. In many areas elephant populations have already gone extinct or are highly endangered.
Over centuries legal and illegal hunting ("poaching") for the commercial ivory trade and, in Asia, the capture of elephants for human use, have been largely responsible for the elephant's demise. The number of wild Asian elephants now comprise less than a tenth of all remaining elephants, and continue to decline in shrinking habitat. In Africa, elephants once inhabited the entire continent, from the Mediterranean down to its southern tip, but the ivory trade coupled with human expansion caused a continental decline in their numbers. By circa 1600 North Africa was devoid of elephants. In modern Africa, poaching for ivory has been fuelled by poverty, political instability and civil unrest coupled with the easy availability of arms. In recent history, between 1979 and 1989, Africa's elephants underwent a dramatic and devastating decline, falling from approximately 1.3 million individuals to an estimated 609,000. Human greed and rising prices of ivory were responsible for the appalling slaughter.
Trade in ivory leads to enormous losses
The killing of elephants for their ivory is the cause of enormous losses in numbers as well as suffering to individuals. The deaths of individuals causes the fragmentation of families and destroys the very fabric of elephant society. Among Asian elephants where females are tuskless and only a small percentage of males have tusks, even subadult and juvenile tuskers are targeted, causing highly skewed sex ratios, as well as trauma and disruption to elephant families.
The tusks of male African elephants average seven times the weight of the tusks of females, and poaching is focused on males and old females. Large males are the primary breeders and the loss of older females impoverishes the social and ecological knowledge of remaining family members, reducing individual survival. In populations with the heaviest levels of poaching, elephant groups may be composed of traumatized orphans bunched together in leaderless groups.
ElephantVoices standpoint is that all elephants should be on Appendix I of CITES and that commercial trade in ivory should not be allowed.
