It's sooner than you think
The above link connects you to an article by Atlas Obscura about how an English coastal community allowed the ocean to recreate marsh in farmland that had been in the same family for 400 years. If I had not written "Soaked" in my upcoming short collection over 2 years ago, I'd assume someone had stolen large parts of the plot to write this story (which is also part of the book Water Always Wins: Thriving in the Age of Drought and Deluge). The scary part is, my story is set 50 years in the future in Louisiana. But this story is now. I actually think is a breath of fresh air that the author acknowledges "water always wins." It is time for humans to stop thinking we will bend nature to our will. Any attempts to do so only destroys nature, and eventually ourselves.
