As an Underwater Graveyard, the Great Lakes Have Claimed Close to 10,000 Ships
Though called the Great Lakes, these massive bodies of water are actually inland seas, and can be just as unpredictable as the ocean.

"even small changes help", and it's not just CO2... big for land use, fertilizer, pesticides, water quality.
Simply reducing beef and lamb consumption to one serving a week -- as recommended by EAT-Lancet -- could reduce emissions by almost 3 billion tons CO2-eq. The equivalent of all of Russia's annual emissions.
