The Catch took a look at why experts are saying water from greenhouses in southern Ontario could be harming Lake Erie. Journalist and farmer Matt McIntosh recently reported on the issue for The Narwhal.
“The greenhouse sector which comprises both vegetables and and more recently cannabis, because it’s expanded so much in recent years, what it’s done is it’s caused a notable jump and sustained jump in nutrient loading levels in local waterways,” McIntosh said.
These nutrients — especially phosphorus — can fuel harmful algae blooms that threaten the ecosystem, and sometimes the drinking water.
