Natural resources are unevenly spread on Earth because of differences in climate, soil, landforms, and the Earth's history like volcanoes, earthquakes, and how continents moved over time. For example, some places have oil because of old buried plants, while others have rivers or forests because of more rain.

When humans take too much from nature—like cutting too many trees or hunting too many animals—it destroys homes of animals and plants, which causes them to die or disappear. This lowers biodiversity, which means we have fewer kinds of living things, and that hurts the balance of life on Earth.

Yes, one day the world can use only renewable energy like solar, wind, and water—but not yet. The biggest problems are cost, weather changes, technology limits, and storage (like saving sunlight for night-time). Rich countries can switch faster, but poor countries need help.

Nuclear energy gives lots of clean power without pollution, so it’s sustainable in that way, but accidents (like explosions or radiation leaks) can be very dangerous and the waste stays toxic for thousands of years. It’s useful, but needs super careful handling.

Solar energy has the most power for the next 50 years because the Sun shines everywhere and we are improving solar panels every year. It's free, safe, doesn’t pollute, and works even in small villages. 🌞
