According to NOAA:
Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Nonpoint source pollution includes many small sources, like septic tanks, cars, trucks, and boats, plus larger sources, such as farms, ranches, and forest areas. Millions of motor vehicle engines drop small amounts of oil each day onto roads and parking lots. Much of this, too, makes its way to the sea.
Some water pollution actually starts as air pollution, which settles into waterways and oceans. Dirt can be a pollutant. Top soil or silt from fields or construction sites can run off into waterways, harming fish and wildlife habitats.
Nonpoint source pollution can make river and ocean water unsafe for humans and wildlife. In some areas, this pollution is so bad that it causes beaches to be closed after rainstorms.
More than one-third of the shellfish-growing waters of the United States are adversely affected by coastal pollution.
So, it makes sense for North Carolina to sell 79,000 acres of coastal forest land into private ownership with the only real restriction on land-use being the highest and best use real estate development doctrine? What else is wrong with the sale of Hofmann Forest?
