I am concerned about water table and ground water quality but this is only because I do not know enough about it to put this issue to bed in my own mind. I suspect though the government when granting leases would consider such risks?
Do you really trust the government to do this? really?
I dont know alot about the issue and maybe some of thing I have seen have been sensationalist but I have seen parts of the movie the guy in the US made about 'fracking' and the movie shows water coming out of house taps that can be lit (set on fire) due to the gas entering the water table. It also shows towns being made effectively uninhabitable due to the process.
As someone else said, this resource isnt going anywhere, why not wait another 30 years to see how badly the miners have stuffed up other countried with it before they stuff up ours
Oh and on the point of veto, If a miner came to my house and wanted to plug in an oil well in my back yard, I would want the right to tell them to get stuffed too and I believe the owners of that land should have that same right.
