This statement is true. The northeast and the Great Lakes regions have a natural habitat suitable for dairy farming. The climate, the precipitation, the grasslands, the water, all make a nice environment for dairy farming. But dairy farming is also making a problem because it causes eutrophication of the water and rise in algae population, thus reducing the oxygen in the water and killing of the fish, so a measures have to be taken so that process stops.
The earth has an area called the Ring of Fire because there is a 'ring' of volcanic activity created by border between the Pacific tectonic plate and 6 others.
