Saving The Earth

Vegetarianism, veganism, planting trees, being a researcher for the rainforest, and many more. But would you include... Love?
When Sarah starts her science class in grade 10, she doesn't think anything of her science partner carter. When carter finds out she's a vegetarian to help the earth, he starts picking on her. When they are assigned a project to do together about saving the earth, they really do get onto the saving part. But from saving EACHOTHER.
