In recent decades, the public has become increasingly aware that the many beautiful and varied forms of endangered wildlife species are an irreplaceable part of the natural system of the earth that must be protected for this and the next generations to come. Today, this is of more concern than ever because of the rapid rate of wildlife extinction around 27 thousand wildlife species being disappeared yearly. At this rate, one third to two thirds of all wildlife species are expected to be lost during the second half of the present century which would be equal to the total past extinctions. Meanwhile, there is much evidence to affirm that, next to habitat destruction, illegal trade offers the greatest threat to world’s rarest wildlife species. Each year, about 350 million wildlife species of fauna and flora are traded on average, irrespective of international law enforcement efforts. Vietnam and England and Wales are CITES country members, both have made a lot of attempts to protect endangered wildlife species, laws relating to crime and also powers provided to law enforcement agencies have been made however they are still in danger and need both countries to do more.
