Ohio, Michigan, and Ontario have joined hands with an aim to reduce algae-forming nutrient pollution into western Lake Erie. They will take steps to reduce the algae by 40% in 10 years.

In a conference on Friday, Michigan Gov. Rick Snyder, head of the Chicago-based Council of Great Lakes Governors, said that the agreement can be signed today at a summit of Great Lakes governors and premiers in Quebec City.

As per him, the goal can be achieved. Ontario Premier Kathleen Wynne thinks that the goal can be considered achievable, but for this, states and provinces need to work in unison. There are a number of matters on which steps needs to be taken like climate change, invasive species and other issues.

"We cannot separate the discussions around pollution from economic and climate change. We need to be tackling all of them at the same time. We need to very much have integrated discussions", said Wynne.

The summit, which started on Friday, will continue through Sunday. As per a statement from Mr. Kasich's office, the promise to bring a decline of 40% in nutrients by 2025 also has an interim target of a 20% reduction by 2020.

For the past recent years, several Great Lakes scientists have been asking for a decline. With passage of time, the idea kept on gaining support from the Ohio Phosphorus Task Force and the US- Canada International Joint Commission.

Experts think that having the support from governors and premiers will help solidify the efforts. Ohio and Michigan have said 'yes' to end phosphorous runoff, which is held liable for algae blooms on Lake Erie. The algae bloom has contaminated drinking water supplies.
