Should we just go through a few of them?

I just have to warn the listeners, this is starting to get into the depressing part of this interview.

Unfortunately, the reef threats are many and varied.

And historically, the most serious reef threat probably started about 1850 with the first cane farm on the Queensland coast in the Great Barrier Reef region because poor water quality has been part of the reef ever since we started farming and developing coastal development and so on.

It remains a serious problem for the Great Barrier Reef today.

primarily runoff from the mainland, bringing sediment from land clearing, herbicides, pesticides, nitrates from the farming.

Obviously, there's point source pollution like sewage treatment plants and developments and ports along the coast.

Do you think Australia is doing enough to protect the reef?
