I won't even summarise this one as it's dear to my heart.
Soil erosion, particularly in riparian zones, is out of control. Soil loss is one of the greatest disasters befalling this planet in plain sight. Cows trampling, farmers spraying, excessive rainfall (same amount of rain falls in heavy storms than consistently over a longer period), windier (less calm days) etc., all add up to pressures that are just getting worse each year.
Pictured below was the deepest water in our local river headwaters. This is what's left after the farmer sprayed 7km of riparian vegetation out and after the floods. From over 2m deep and long to ankle deep. Platypus and Lungfish were present before.

And this is just a normal creek around here. No one is doing anything about it. Farmers aren't, that's for sure. It's their land.
