Nature
Nature refers to the physical world and everything in it that humans do not make. It includes:
- Living things like animals, plants, fungi, and microorganisms
- Non-living elements such as mountains, rivers, oceans, rocks, air, and weather
- Natural forces like gravity, sunlight, wind, and the water cycle
Nature operates through systems and processes that sustain life on Earth. It provides the environment we live in, the resources we use, and the beauty we admire. In simple words: Nature is everything that exists in the world without human creation - like trees, animals, rivers, and the sky.
Climate Change
The long-term changes in the Earth’s average weather patterns is called Climate Change. Such changes can be natural, due to changes in the sun’s activity or large volcanic eruptions. But since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels like coal, oil and gas. The natural causes, human causes, effects of climate change and controlling measures are discussed here below.
