"A few years ago, the one part I visited was stunning, so there isn't an issue at all."
But in fact half of the reef has died since then: https://www.theatlantic.com/science/archive/2018/04/since-20...

The two issues are rising water temperatures due to global heating; and outflows of nutrients and to a lesser extent, effluent, due to industrial agriculture, mostly animal agriculture.
For the first one, we need to give up fossil fuels which means cutting down our consumption; for the second, we need to cut down our consumption of resource-intensive, waste-intensive foods.
There isn't going to be some magical "technological idea" where we can continue on much longer with our two centuries of unchecked exponential growth in consumption, and exponential growth in pollution, and not devastate our biosphere.
People have been telling me for decades about such a solution and yet it never comes. Each new technology just spurs people on to new levels of obsessive consumption and waste.
