To those who say genetic engineering is dangerous and scary and bad - bite this!

Mine-Sniffing Plants

See the comments for the original post.

Unfortunately Aresa didn't take into account something known as 'nitrophiles' which are widespread nitrogen fixing bacteria who release NO2 as a by-product and therefore could also trigger the plant to change colors causing enormous amount of effort and strain to dig up mines that are non-existent. I think it's a great idea, but I am against planting non-native plants that could overtake natives and genetically modified plants that could affect the genetic community at large.


Introducing non-native plants or animals can have a huge ecological impact.

Well, yes, it can have an ecological impact; but the land is pretty much useless as is, to wildlife as well as humans. Which is better, to try to salvage the land for something, or let it go to waste?

I suspect similar arguments, were used to justfy introduction of new species into other areas. Australia has a rather depressing history of these sorts of introductions.

It's not necessarily the case that the only options are to introduce the plants or leave the land as useless. There may be other options for finding and removing the mines. Not using the land may also be an option in some cases.

The ecological impact of introducing the plants may not be limited to areas that have mines. The seeds could be blown into other areas, or the plants can reproduce and spread. Either way, the plants can out-compete native species, which could have a cascading ecological effect (yes, there's lots of "coulds" there :-).
