C. Answer the following question:

Eating cheeseburgers affects the environment in many ways. First you have to feed the

cows. You need a lot of water to grow the food for them. Then you need wheat to make

the bread that the hamburger goes on. That needs water too. Once you have the beef you

have to transport the meat from one place to another. You also have to keep it cold. To do

all of these things you need a lot of energy. And this produces a lot of CO2. And carbon

dioxide isn’t the only greenhouse gas that’s created. Cows also produce another

greenhouse gas called methane when they make waste. And cows create a lot of waste.

When you add it all up the result is a very big number.
