Accessibility

With web accessibility, people with disabilities can use the web. People with disabilities can perceive, interact, understand and navigate the web. This also allows them to be able to contribute to the web as well.
Accessibility encompasses all disabilities that affects web usage. These disabilities are: visual, auditory, physical, speech, cognitive and neurological.
Many people in the world today have disabilities that cause them to have difficulty using the web. Most web sites right now have an accessibility barrier making it difficult and sometimes impossible for people with disabilities to use the web.
However, web accessibility can also benefit people without disabilities (i.e. people with broken arms and people with changing abilities due to aging).
Overall, accessibility is important because it is an important resource in many aspects of our lives today in areas such as: education, employment, government, commerce, health care, recreation and more.
Without accessibility, people with disabilities would not have the same opportunities in their lives as everyone else; and that I would think could be borderline discrimination because they should have the same opportunities as everyone else when it comes to education, employment, health care, etc.
