Three elementary school students from the future discovered a magical chip, which stored a series of documentaries. Every time they watched an episode, they would travel to the past and embark on an adventure to save the earth.
With each episode saved, the future Earth environment will become a little better.
The future of the earth depends on us now to save it!
Purpose: Everything we do now will have an impact on the future. There is no time machine in reality. Protect the environment and start from now.
