Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.
Mozzarella is the correct spelling. Mozzarella is a moist white unsalted unripened cheese of mild flavor and a rubbery texture.
Pizza hut uses skim milk mozzarella on it's pizza, at least in the USA. Not sure what they use in other countries, but I would imagine it is still the same. Skim milk mozzarella is extremely stretchy, but loses a little on the flavor end. More expensive pizzerias normally spring for the full fat mozzarella cheese. Dominos uses a mix of cheese, made up of mozzarella, Pecarino, Parmesan, and asiago cheeses. I think in their most recent reboot they switched to part skim mozzarella but I am not one hundred percent on that.
