Home, To Zero!

Earth is no longer in danger! On a mission to save the planet, humans are isolated from it and continue to live in specially designed capsules.
At different stages of the mission, they succeeded and returned all natural resources to the earth, saved endangered animals and birds, and bred, and created new species that only benefit the ecosystem.
The last mission is the ceremonial destruction of the last polyethylene. After that, people must leave their home planet and go to discover a new world.
The celebration is interrupted by an unexpected glitch...
The mission is in jeopardy!
Will humans be able to fly into the future, or will all achievements be lost in the water?
