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.
