Basketball: (21st century)
Basketball is a big part of my life, i play it almost everyday. In the picture there is NBA player Kevin Durant (#35 in white). He plays for my favourite team the Oklahoma City Thunder.
This is what basketball looks like today but 50 or 60 years ago it looked much different!
As you can see much different in terms of the clothes they wear and actual people playing. Also in the first picture there are all kinds of people and different skin colours. In the second picture there are only white people on the team.
We heared a lot of how the human race now is not learning from mistakes which is making the world a harder place to live but this proves that we have grown as a race and as human beings. It might take a while but most things can be fixed.
