Dozens of you have taken a stand to end modern-day slavery. For the second Freedom Project iReport assignment, we challenge you to take the next step and spread the message even further.

Consider this:

-Each year, between 600,000 and 800,000 human beings are captured and transported across international borders.

-There are at least 10 million slaves in the world today.

-There are more slaves now than any point in human history.

Here's your assignment:

1. Build it. CNN is using the paper airplane as a symbol of the path towards freedom. We want you to make a paper airplane of your own. On one wing, write one of the three statistics above. On the other wing, write a message of hope for the victims. Then add your name.

2. Show it. Upload a close-up photo of your airplane on CNN iReport. Extra points if you also upload a video of your plane flying through the air.

3. Pass it on. Give your plane to a friend or a stranger. Encourage that person to write their name and pass it on to others.

The deadline is June 15. Check out the submissions we've received so far, then add your own. We look forward to seeing planes and messages from across the world and sharing them on CNN.
