Answer: Sustainable development refers to the kind of developmental activity that ensures economic progress without affecting nature and our ecosystem. The issue of sustainable development was first discussed in 1986, in a report by the Bruntland Commission. The Millennium Development Goals (MDGs), which began in 2000, ended in 2015. The United Nations then announced a 15-year ‘Sustainable Development Goal’ or SDG. UN member states need to meet the 16 goals of the SDGs from 2018 to 2030. In 2015, the United Nations adopted 16 Goals and 179 Supporting Goals to ensure prosperity for all as poverty alleviation, global protection and a new sustainable development agenda. Various organizations of the country including the government of Bangladesh are working to achieve this goal. ‘Youth Change Maker’ is one of them. They are committed to working towards achieving the SDG targets by ensuring maximum participation of the youth of the country.
