Green Options

Scientists in South Africa are testing a genetically engineered tobacco plant which detects the presence of nitrogen-dioxide, a marker for landmines, to turn red, in the hope that it may eventually be used to clear mine fields in post-conflict zones around the globe.

The team is part of a joint initiative of University of Stellenbosch and the Danish biotechnology firm, Aresa, which has developed the “RedDetect” bio-sensor technology in a weed called Thales Cress.

The weed changes color from green to autumnal red when it detects nitrogen dioxide leaching from mines buried in the soil.

Because the weed is too small to be seen from a safe distance, the scientists went looking for a more viable alternative, and landed on the tobacco plant, which grows easily in most parts of the world, with a little help from genetic engineering.

This week, world leaders of the G8 Club and their colleagues from the regional blocs of Asia, Africa and Latin America, are gathered in Hokkaido, Japan for yet another round of talks in which climate change will ultimately feature.

Apart from parading their own theoretic short and long term goals and how best to approach this growing problem while clouding their own best national interests, making concessions for climate change may prove harder than committing to curb global carbon pollution.

As the main players at the Hokkaido summit, were the G8 Club, and China, Brazil and India, to pose and think about climate change issues as possible recipe for wars, the plight of the millions of victims of the conflict in Darfur, Sudan would connect with their jostling for the best breathing space.
