When it comes to the end of war, who takes care of the rests? Since there is a massive use of landmines, almost since 50 years, there has been also a parallel developement on methods of how to detect them.
In most of the first detector cases, it was animals who keept the worst part of the job, such as dogs or rats, making it as usually a feeling of total careless for other living beeings in our planet's life. Governments make the problem and who cares about a rat more or less??
Other methods are trained mongoose animals atached to some robot, or metal detectors, but it stills in need of someone to bagger, with a huge potential harming risiko.
.
So there are some robots not just for detecting but also for exploding mines and some modified bacterias which can detect explosives,. One type of bacteria uses fotoluminescence and the other needs the TNT for its methabolic porpuses. Nevertheless this methods are really expensive and no method ist without failure and we surely hat to thing twice about modifying a bacteria species and letting it free in the enviroment, because of the evolutive process.
