According to conservationists, why does the Internet pose a threat to endangered species?

Conservationists say the Internet has emerged as one of the biggest threats to endangered species.
    It is easier than ever before to buy and sell anything from live baby lions to polar bear pelts on the Internet, as buyers and sellers take advantage of the anonymity and vast global market—the World Wide Web can offer. The findings were presented at the 175-nation Convention on International Trade in Endangered Species, which is meeting in Doha, Qatar. Several proposals to give endangered species more protection were defeated. A proposal from the US and Sweden to regulate the trade in red and pink coral was defeated. Delegates voted the idea down mostly over concerns the increased regulations might impact poor fishing communities.
