How is the sun helpful and harmful?

The sun is essential for life on Earth, providing the energy needed for photosynthesis, which supports plant growth and sustains the food chain. It also helps regulate the planet's climate and weather patterns. However, excessive exposure to sunlight can be harmful, leading to skin damage, heat-related illnesses, and an increased risk of skin cancer due to harmful UV radiation. Balancing sun exposure is crucial for health and well-being.
