Okay kiddo, do you know what transportation means? It's when you go from one place to another, like riding your bike, taking the bus or walking.
So, there is a group of grown-ups called the Active Transportation Alliance and they want to make sure that people can safely and easily ride their bikes, walk or take public transportation to get around the city. They care about this because it's not only good for our health but also for the environment.
They talk to the people who "drive" the city and ask them to make bike lanes and sidewalks and safe crossings so that people can get around and feel safe. They also teach people about how to ride their bikes safely and why it's important to take care of the earth.
Basically, they want us to move around without cars as much as we can and instead use our own two feet or bikes to get from one place to another so we can stay healthy and happy while helping the environment at the same time.
