The Great Barrier Reef: In the "Pollution" section there is no talk about how increasing CO2 levels raise the acidity of the water. Making it too acidic for creatures to live there causing them to die. There has been a 25% increase in acidity in the past two centuries. (National Geographic) Rising acidic levels play a really important role in the declination of sea wildlife. Something that needs to mentioned in a encyclopedia.

Over-fishing: There's only mention of, " With declines in the abundance of large predatory species, the abundance of small forage type increases causing a shift in the balance of the ecosystem towards smaller fish species." It should be mentioned that this can happen vice versa. For example the prey gets whipped out because the predator. This leads to issues of the predator needing to adapt or dying off.

Water Pollution: There is talk about testings such a physical, chemical, and biological. What do these numbers mean, and how do they determine what the government does to slow down water pollution? I think this should be added to this section. I feel like this is something important that needs to be noted.
