Atmosphere: Difference between revisions

[[Earth]], and later on, the [[Terraforming|terraformed]] [[Mars]]' atmosphere, was 80% [[nitrogen]] and 20% [[oxygen]]. ([[AUDIO]]: ''[[The Resurrection of Mars (audio story)|The Resurrection of Mars]]'') [[New Earth (New Earth)|New Earth]] had the same atmosphere as Earth, which was why [[human]]s made it their new home after Earth was destroyed. ([[TV]]: ''[[New Earth (TV story)|New Earth]]'')

 

Due to [[human]] activity, Earth had a lot of toxins and dioxins in its atmosphere, which would have provided decent nutrition for the [[Nestene Consciousness]]. ([[TV]]: ''[[Rose (TV story)|Rose]]'')

During [[the Year That Never Was]], Earth's atmosphere was temporarily opened to unleash an army of [[Toclafane]]. ([[TV]]: ''[[The Sound of Drums]]'') The [[2009|year]] after that, the [[Tenth Sontaran Battle Fleet]] made [[Luke Rattigan]] develop the [[ATMOS]] in [[car]]s across the entire planet Earth. This was part of their plan to poison Earth's atmosphere with [[Clone Feed]], so Earth could become the new clone world for the Sontaran species. The [[Tenth Doctor]] later cleared the atmosphere, saving the planet. ([[TV]]: ''[[The Poison Sky]]'')

In an [[Donna's World|alternate timeline]], Earth's atmosphere was poisoned by the Sontarans and then cleared by [[Torchwood Three]]. ([[TV]]: ''[[Turn Left]]'')
