Our oceans are widely unknown and only a fraction of the seas are protected. Yet, the mining company that is planning to "break up the top layer of the seabed" claims that the site will recover quickly and that life will return within 5-10 years.

I am not a marine biologist but that does not sound right to me. This is the first time mining has taken place in the deep sea and so how can the long term effects be known? Unconsidered remarks from money making companies should not be trusted by default. How they got the permission in the first place baffles me. We dump our rubbish in the sea, disregard the scientific caps on fishing and agree on large scale mining of the seabed. Would we be as bold if we could see the effects? Just because we can't see it- it doesn't mean it's not there.
