"Sustainable" refers to practices and methods that meet our current needs without compromising the ability of future generations to meet theirs. This concept is often applied to areas like environmental conservation, energy use, and agriculture. For example, using solar energy helps reduce reliance on fossil fuels, ensuring cleaner air and a healthier planet for years to come. In everyday life, being sustainable can mean making choices that are eco-friendly, such as using reusable bags instead of plastic ones or supporting local farmers. These small actions contribute to a larger goal of protecting our ecosystems and promoting a balanced relationship with nature.
