We are exploiting fish stocks at an alarming rate and we have reached unsustainable levels of wild fish catch. What are the best solutions to overfishing?
In addition to repopulation, we could also focus on conserving and restoring marine habitats, which would help replenish and guarantee the continued existence of seafood stocks and other vital marine life.

Oceans cover more than 70% of the Earth’s surface, and they contain a vast amount of saltwater. Osmotic power plants can be built where freshwater rivers meet the sea, to take advantage of the natural osmotic gradient. The energy thus generated can be considered a completely renewable and sustaina... Read more

Eventually, coastal cities threatened with rising tides and bigger storms could use not just the waterfront, but also the water, as places to build housing.
Sea levels are rising due to climate change. Many coastal cities are at growing risk of flooding. Architects are trying to react to this development with new ideas, such as floating cities.
Japanese designers N-Ark say that the futurist city - called Dogen City - will also act as a ‘medical city on the sea’, with residents receiving medical care on a daily basis.

Desalination is a process by which salt and brackish water is pulled out of the ocean and run through a system to result in clean, drinkable water. However, desalination is not a fail-safe process and carries with it many environmental repercussions.
Desalination is key to providing fresh water to millions of people around the world. Yet, it can harm marine wildlife, takes a lot of energy, and it’s often not sustainable.
There's finally a way to filter the microfibers in your laundry from entering the water supply, and into our oceans with this new washing machine filter.

I thought this idea was a joke, but…
Nice idea if it helps but sounds like it could be a way to just landfill dump animal carcasses in the sea. So not good.
urr, yeah, but what do you do with the rest. every day!
How to save coral reefs? Same as saving anything, keep humans the hell away from them.
I am pasting part of an answer from Quora here for those who don’t get it…
Does the life jacket need to know where it is?
Suppose it gets its position from GPS.
Then what?
No real need to have it built into the jacket, everyone should have a GPS beacon attached to them anyways.
A beacon, mirror, whistle and stobe light would be more useful. Why do you want to know where you are while stuck in a big ocean?
They are such a great idea. I can’t imagine going out without GPS. Floating around until you die isn’t a nice prospect, Yay for GPS.
The water is good for industrial purposes but you don’t want to make communities rely on it as it lacks the minerals they get from regular water.
true, and the salty brine gets pumped back into the sea near the water intake. Not solved yet.
Nice idea but it’s not that simple, an estimated 76 million tons of CO2 are emitted annually as a result of desalination processes.
Cigar! Looks like these are on their way!
These filters should be made compulsory – plastic is killing us bit by bit.
Close but no cigar?
Already saving lives without risking others – imagine, lifeguards don’t even need much training if using these. could be easy to volunteer for.
cool these exist already, brill idea
5000 pounds per night. So its early days for these things – can’t wait till they take off and bring the prices down.
just WOW. Great idea, we need one in the UK, though not sure what sealife we would see on our coasts.
