Military aid

The news that drug cultivation in Colombia has fallen by 32% comes
amid concern over its controversial crop-spraying programme.

The scheme is financed by the US and is Washington's principle
condition for continuing military aid.

But peasants and human rights groups oppose the spraying of toxic
chemicals over drug fields, many of which are in the vulnerable
Amazonian rainforest.
The glyphosate chemicals, which are sprayed from planes kill all plant
life, not just drug crops, and leave peasants destitute.

Critics allege the spraying simply feeds displacement and leads to
more virgin rainforest being cut down, and that manual eradication is
the only way forward.

Goodness, well, at least it isn't Agent Orange...and I sure hope we
don't find out 20 years from now that it is as bad as Agent Orange.
