Sonic Weapons, Africa’s Green Revolution and Volcano Storms

Science and Environment Round Up
By Tom Drake

There has been controversy concerning exportation of

Sonic Weapons

from the US to China. The manufacturer LRAD is understandably shy of

calling their product a weapon as the practice of exporting arms to

China has been banned in the US since the Tianamen Square massacre in

1989. Their ‘device’ works by directing high power sound waves at the

target. This is a painful and effective and while there is significant

risk of hearing damage it is generally less harmful than being shot!

However, what are the social/political consequences of a government

having access to a relatively non-harmful weapon? That it


more acceptable could in fact be its greatest threat. If use of these

weapons becomes commonplace in a police force this would subtlely but

significantly increase the level of control a government has over its

people. Shooting your own people with bullets would cause outrage

across the globe but shooting them with sound? This is all the more

likely if the government in question already has an authoritarian

streak. Campaigners are concerned about the use of such devices at this

year’s Olympics in China.

Kofi Annan, the former UN Secretary General and now Chair of the Alliance for a Green Revolution in Africa (AGRA), has been discussing

the importance and practicalities of generating and agricultural boom

in the troubled continent. His words were big on intention and what needed to be done but the how

was glossed over. Some of the issues surrounding the proposed ‘Green

Revolution’ have been discussed previously on The Daily Banter; Philanthro-capitalism:

‘A white man’s dream for a black continent’
, Institutional Reform on the African Continent, Philanthro-Capitalism

– The Eco Issues

Although Annan doesn’t mention Gates or a place for western investment

and industries this is where both the solutions and the problems arise.

With large scale corporate western involvement how do relatively weak

African governments retain control of their land and resources? How can

the production-driving profit motive be reigned in to avoid

environmental damage in the form of lost biodiversity access to clean


In a very much related area Biopiracy, the act of patenting

biological material such as foods & medicines, is in spotlight this

week. A US company which has held a patent on a type of Mexican yellow bean

since 1999 recently had the patent overturned. The company had been

charging licensing fees on imports of the beans from Mexico. While

patenting biological material (or anything else) already in common

usage is not allowed, a legal challenge takes time and money.

Last week two of the most destructive and chaotic forces in nature collided in Chile as a Volcano eruption met a lightning storm.

You can see the black and orange plume on the right mixing and reacting

with the electrically charged storm cloud. The Chaiten volcano had been

dormant for hundreds if not thousands of years. Its dramatic explosion

has resulted in the evacuation of ~5000 people, covering near-by towns

in 15cm of ash.
