Great accomplishment

Kudos to the leaders of Ontario, Quebec and eight U.S. states for reaching agreement on a deal to protect the Great Lakes:

Political leaders from Ontario, Quebec and eight U.S. states will sign a new deal Tuesday aimed at banning large-scale water diversion projects from the Great Lakes...

The agreement is also expected to call for new measures to prevent invasive species from entering the lakes, and reducing the levels of PCBs, dioxin, mercury, pesticides and other toxins.

I'm not sure how much authority the states have to make such agreements binding on themselves. But at the very least the deal shows a strong intention on both sides of the border to ensure that the Great Lakes will be safe for the foreseeable future - and all involved deserve credit for that.
