I think it is a great way for the people of the world to understand just how small we are. When seeing the whole planet from above, it is a reminder that the Earth is a delicate place, and it lets everybody experience what astronauts experience without traveling to space themselves. It also shows the improvements in technology that we can now take pictures in outer space to share with the world.
Thinking about how small we are in the entire space galaxy is scary. It makes you feel tiny and unimportant. I watched the movie interstellar and i can't stop thinking about the topic.
