A bit of hysteria in this one. A 25 ton machine gets stranded and the environmentalists are up in arms?
It's not the machine, it's the entire prospective industry it's a proof-of-concept for. The principle is basically like open-casting entire areas of the sea-floor. It might not dig as deep as surface open-casting, but it potentially scrapes away all the surface sea-life.
The risk is greatly exaggerated. Single cell protein, greenhouses, hydroponics, and other technologies should be able to function even under worst-case conditions of extreme ecological and environmental collapse.There needs to be some sort of brake on the system or we will not have a planet able to support us.
Long-term gains?foist on future humanity in exchange for short term gains?
This planet supports more than one race and we are losing more species all the time. I suppose you want to rape the planet until nothing bus ashes remain, hoping no doubt, to move on and do the same to another planet. No thanks. Remember this, all the crap we chuck into the sea, earth and air comes back to us via the food chain. Still happy?The risk is greatly exaggerated.

Far from the magnitude of environmental threat, the key determinant of how well we will cope is national wealth and mobilization capacity.
Even if the planet is unable to support us, we will survive if we can support ourselves. If we cannot support ourselves, no amount of planetary support will help.
No, because India is not posting happy GDP growth figures this year, and its lack of wealth and state capacity is already killing ten thousand Indians a day. Lake Chad is drying up, and Nigeria and Chad are suffering insurgencies from environmental degradation - which they do not have the cash to cover. The world desperately needs money, money, money. We can worry about the seafloor when India's GDP/head hits 20,000USD, and the poorest nations head past 10,000USD/head.Still happy?
The Chinese had the right idea. Screw the environment until GDP/head hits 10-20k, then start going green as fast as possible. Now, China is well-insulated from the worst of climate change, and expects to be carbon-neutral by 2060. The Chinese can build seawalls, relocate cities, build water management systems and desalination plants... In a worst case ecological collapse, the government forces everyone to eat rations made from bugs. No mass starvation for the Chinese.
