Peace, democracy, and development can be achieved through inclusive education and practices. Inclusive education fosters mutual understanding between groups, reduces disparities, and builds shared democratic values. It also prevents conflict by addressing sources like selfishness, prejudice, and exploitation. Sustainable peace is built by respecting diversity, promoting non-violent conflict resolution, and participating in society. Democracy values inclusion, freedom, and respect for diversity to prevent exclusion. Inclusive education and valuing all cultures, abilities, and identities despite differences are crucial for unity, well-being, and sustaining peace, democracy, and development.
