Like with languages, there are certain barriers that people experience when they're trying to connect with the world. Those in wheelchairs, for example, basically find half of the world inaccessible. Because of bad roads, lack of sidewalks, stairs, and steepness, there are so many places that remain frustratingly out of reach. Us able-bodied people might never realize it, but it affects your quality of life enormously.
Luckily for us, a future where everyone has an equal opportunity for enjoyment is right here, right now. From bionic limbs to the ingenious stair-climbing wheelchair pictured, inventors are constantly coming up with ways to open up the world. Now, more than ever before, the barrier for entry has been significantly lowered. And isn't it great to share this wonderful planet?
