Biopiracy:
Pirates were a bloodthirsty lot who stole and killed to make themselves rich.
Often, they ended up getting killed themselves. They were outlaws, hunted down
whenever possible by naval ships from various countries. The biopirates are a
bit different. They don't kill, they patent.
And they are completely protected by the law so nobody hunts them. They are usually
employed by corporations or even governments to go and collect genetic material
(e.g. seeds) from places like India or the Amazon.
In India, the neem tree has been used by people for thousands of years for things
like killing pests and as a medicine. An American company patented the tree which
means that anyone using it should, by law, pay the company. This
has outraged many people on the receiving end of this legalised theft. The Indian
scientist Vandana Shiva explains that the real cause of biopiracy is the left-over
colonial idea dating back to Columbus’s 'discovery'. 
Columbus
'discovered' the Americas in 1492 and from that time on, Europeans began to take
the land away from the native Americans, the original inhabitants of what are
now Latin and North America. (They did the same in Africa and Australia.) The
Americas became Europe's colonies, to be exploited in any way - including killing
native people if they objected. 
It's
this same colonial tunnel vision which permits the piracy of gene resources and
knowledge from non-Western cultures to be claimed as 'invention'. This means this
once-free heritage of seeds or knowledge can be protected by patent. This is just
legalised stealing. Knowledge now strangled by patents (called in legal language
'intellectual property rights' or IPRs) used to be freely shared between everybody
who needed to use it. 
Now,
after patenting, people have to buy it to be able to use it legally - including
those who had learned it as it was passed down through each generation in their
communities. I don't know what you think about that but I think it's wrong. Your
laws need changing!
