Terra Nova: What I've learned so far

• Earth is completely ruined environmentally, to the extent that the air is so polluted, not even rebreather masks can handle it.
• Families are limited to only two children. Anymore and there are legal consequences. The son of the main character mentioned fines.
• There's a time machine. Some kind of "time fracture" leading to an alternate reality was discovered and a machine was built to transport colonists to the past of that world.
• There are dinosaurs.
• Stephen Lynch plays the commander of the colony. I've yet to see any Navi, though.
• Giant oxygen eating leeches. They're used to siphon off excess oxygen from people having a hard time adapting to the fresh air.
