Nature encompasses the natural world, including everything that is not man-made, such as plants, animals, land, water, and air. It's the foundation of life on Earth, providing essential resources like food, clean air and water, and a home for countless species. The interconnectedness of nature, from the smallest insect to the largest tree, highlights the delicate balance that sustains all life. However, human activities like deforestation and pollution pose significant threats to this delicate equilibrium, making conservation efforts crucial for the future of our planet.
