Sustainability is the practice of living in a way that protects nature and natural resources. It means using resources carefully so that they are available not only for us but also for future generations. A sustainable lifestyle helps maintain balance between humans and nature.

Natural resources like water, forests, and fossil fuels are limited. If we waste them, they may disappear one day. Saving water, avoiding plastic, and switching off lights when not in use are simple ways to support sustainability in our daily lives.

Sustainability also focuses on protecting plants and animals. Deforestation and pollution destroy their homes and disturb the food chain. By protecting forests and wildlife, we help maintain biodiversity, which is important for the survival of life on Earth.

Another important part of sustainability is clean and green energy. Solar, wind, and hydro energy reduce pollution and are safe for the environment. Using public transport, cycling, and walking also help reduce air pollution.

In conclusion, sustainability teaches us to be responsible citizens. Small actions taken by each person can bring big changes. By following sustainable practices, we can protect our planet and ensure a bright future for all living beings.
