Sustainable development involves using resources in a way that meets current needs without compromising future availability. It allows future generations to meet their needs as well. Sustainable transport can create jobs, improve safety, increase access to opportunities, and save time and money for people and governments. Sustainable energy is renewable and produces little pollution, replacing fossil fuels. As renewable energy becomes more common, it provides social equity and contributes to long-term economic sustainability and national security. Sustainable agriculture uses environmentally-friendly farming that allows crop and livestock production without harming people, nature, or resources now and for future generations.
