Reduced-lead bullets, environment friendly mines and recyclable explosives are among the developments being put forward by arms manufacturer British Aerospace (BAE) as part of a major investment in ecologically-sound weaponry. The company, one of the world's biggest arms-makers, says it has been making investments in creating products that reduce the collateral damage of warfare. "We're looking across a range of all the platforms and areas we produce, and trying to improve all the mechanisms," Deborah Allen, director of corporate responsibility for the company, told BBC World Service's Culture Shock programme. "Everything from looking at making a fighter jet more fuel-efficient and looking at the materials that munitions are made of and what their impact on the environment would be." The idea behind the lead-free bullets, for example, is that if they get lodged in the environment, they "do not cause any additional harm". Whats next? Solar powered electric chairs?
