B. It grows as nuclear fusion in its core produces more matter.
Answer:
Humans alter their environment in many ways. We burn fossil fuels to produce electricity and to power cars, airplanes, and much more. We also remove land to build businesses, homes, and stores, and to grow food. We cut down forests to make things like paper, desks, and houses, and we hunt or raise animals for food. And lastly, we divert rivers to store water in reservoirs and to irrigate farmland.
