Hello everybody, I'm astronaut Chris Cassidy on board
the International Space Station.
Happy 50th Earth Day!
(music)
Earth Day, to me,
is a time when it's very appropriate
and applicable to reflect on
how important Earth is to all of us.
What does that mean to me?
To me, it means Earth is our home.
Earth is a spaceship for all of us.
We're all astronauts on board that same ship.
We need to take care of it.
Like Anatoli, Ivan and myself, we're taking care of
the International Space Station right now and if we don't do our job,
the mechanical equipment won't work well
and we could do damage to the space station, just like
all of the people on Earth need to do their job, do their part, to keep Earth healthy.
Simply put, it's a time to reflect on what you can do
in your own life. Each person can make those decisions
that collectively can impact the world.
