Like all animal protein, milk acidifies the body's pH, which in turn triggers a biological correction.

They are written in a type of ink that acidifies if exposed to varying temperature and humidity factors.

"We've known that acid rain acidifies surface waters, but this is the first time we've been able to compare and track tree growth in forests that include soil changes due to acid rain," says Lawrence, who led an international study based on the Dokuchaev collection.

SO2 causes acid rain which harms vegetation, damages buildings and acidifies water.

The main protein in milk, casein solidifies when milk acidifies. It is already used as a food supplement and as an ingredient in adhesives, finishing materials for paper and textiles, paints, and other nonfood products.
