Answer:

Earth is a serene world surrounded by ocean and land. A magnificent world is rich in lakes, rivers, mountains, rain forests, and living beings known as animals. There was no pollution or contamination in the ecosystem, seas, or atmosphere. The sky was clear and blue, and the lakes were pure, clear, and unpolluted. Fish swam freely, birds chirped in the rain forest, and gigantic whales swam freely in the pure blue water.
