List two ways in which oil refining benefits society and the environment?

Refined oil is used in so many processes that allow us to have a good life. From medicines to transportation refined oil provides the link that keeps the world functioning. Without refined oil, the ability for farmers to create sufficient food would be seriously curtailed. Starvation of billions would be the natural result if oil refining were to cease. Many modern medicines contain petroleum products from refining also. A shorter lifespan would be the natural result here. Transportation would be almost impossible without refined oil also. Imagine a world where you could not have fresh fruit from other parts of the world or never seeing family again if you moved 100 miles away. Without refined oil, many of the clothes you wear would not exist and the colors would be less colorful.
