Sustainable methods refer to practices that meet current needs without compromising the ability of future generations to meet theirs. These methods often focus on reducing waste, conserving resources, and minimizing environmental impact. Examples include using renewable energy sources like solar power and wind energy, as well as implementing recycling programs to reduce landfill waste. In agriculture, sustainable methods involve techniques such as crop rotation and organic farming, which promote soil health and biodiversity. These practices aim to create a balanced ecosystem that supports both food production and environmental conservation, ensuring that natural resources remain available for future use.
