 Accessing public services for most people is often taken for granted. But for Eric Grassian, 57, accessibility for all users has been his personal mission for more than two decades. The UN Convention on the Rights of Persons with Disabilities estimates that of the 6.25 billion people predicted to be living in urban areas by 2050, an estimated 15% or 937 million will be persons with disabilities. In all the countries in the world, we will be free, we will be in the middle of the world, we will be there, we will be there, we will be at the center of the world. Not only in the center of the world, not only the center but all the countries around the world, the United States, all of them. Participation is key for changing attitudes around persons with disabilities And what needs to be particularly supported is that people with disabilities can be part of societies on an equal basis with others.
