   Biopiracy is the illegal appropriation of life -- microorganisms, plants and
   animals (including humans) -- and the traditional cultural knowledge that
   accompanies it.
   Biopiracy is illegal because, in violation of international conventions and
   (where these exist) corresponding domestic laws, it does not recognize,
   respect or adequately compensate the rightful owners of the life forms
   appropriated or the traditional knowledge related to their propagation, use
   and commercial benefit. Biopiracy commonly operates through the application
   of Intellectual Property Rights (IPR) (primarily patents) to genetic
   resources and traditional knowledge.

   Many a times big tankers carrying oil get damaged or wrecked in the
   mid-oceans.before remedial measures are taken,oil in large quantities leaks
   into the sea water.oil being lighter,spreads over surface of the sea over a
   large area.this stop the supply of oxygen in the sea water.further,oil clogs
   the gills and respiratory organs  of other aquatic animals.for miles
   together,the sea water becomes unsuitable for the sea animals.birds feeding
   on fishes,when dive in the water to catch the fish,also get their wings
   drenched in oil.these birds die in hordes.thus entire marine ecosystem gets
   drenched.
