21. Habitability in the S-boats were poor.22. They were also criticized for their habitability , with inadequate ventilation and food storage. 23. The past flow of liquid water demonstrates the planet's potential for habitability . 24. Temperatures and pressures needed for habitability are set by the triple point of water. 25. See Planetary habitability # Orbit and rotation and Axial tilt # Long period variations. 26. Because of this, the chances of habitability may be lower than originally estimated. 27. Drainage systems are a crucial compromise between human habitability and a secure, sustainable watershed. 28. This is one consideration in terms of planetary habitability or the possibility of extraterrestrial life. 29. Habitability would be increased by the addition of fresh water distillation units and air conditioning.30. Planetary engineering can also be applied to keep habitability of Earth in the far future.
