Biofuels : Friend or Foe?

Now imagine thousands of acres of landcovered in a plant that sucks up
far more of the country’s precious water than indigenous vegetation, a
plant that no animal can or will eat and four seeds of which can kill
a child, a plant that has little economic potential and requires
millions of Rand to remove to prevent its spread to new areas, coupled
with impoverished rural communities who no longer have any land left
to graze their cattle or goats and who are disillusioned by broken
promises of work for all.
