Sustainable development is no longer just an option; it is an absolute necessity for our survival. In order to ensure a secure future, all members and stakeholders of society, including producers, consumers, civil society, policymakers, government officials, and research institutions must collaborate. Bangladesh is currently facing numerous challenges that are severely impacting our living standards. To change our situation, we must adopt three 'I': integrity, innovation, and implementation. We need to improve our actions, words, and attitudes in order to shape Bangladesh's future. This book will outline the primary mechanisms, highlight various social policies, and draw a comparison between Bangladesh and developed nations.
