Since the original post didn't say what the petition was about, I'll quote it.
Baby Seals Need Your Help!
This year, by late March, the Canadian seal killers armed with clubs and rifles will go again to the nursery floes of the harp and hood seal, to massacre them in the largest mass slaughter of marine mammals on this planet!
In 2003 alone, 350,000 seals where killed in this brutal way and this year and in 2005, each year they will kill 350,000 more to make a total of over a MILLION seals killed within 3 years.
Please sign this petition and send it to everyone who cares for the animals in the world to stop this extremely cruel slaughter of innocent seals in Canada. ..... See full petition below
