Ecology is the study of how living things interact with one another and with their surroundings. An ecosystem includes organisms such as plants, animals, and microorganisms, as well as non-living parts such as water, soil, and air. These parts are connected: for example, plants use sunlight and water to grow, while animals depend on plants or other animals for food. People can disturb ecosystems through pollution, cutting down forests, overusing natural resources, and releasing greenhouse gases that warm the planet. Pollution can harm wildlife and make air and water unsafe, while habitat loss leaves many species with fewer places to live. People can help by saving energy and water, using reusable items, sorting waste where facilities allow it, and choosing to walk, cycle, or take public transport when possible.
