Nearly everything we do each day is connected in some way to Earth: to its land, oceans, atmosphere, plants, and animals. The food we eat, the water we drink, our homes and offices, the clothes we wear, the energy we use, and the air we breathe are all grown in, taken from, surround, or move through the planet.
By 2025, eight billion people will live on Earth. If we are to continue extracting resources to maintain a high quality of life, then we, as individuals and citizens, need to know more about our planet—its processes, its resources, and its environment. And only through the study of the earth sciences can students understand and appreciate our complex planet. (Geological Society of America)
