Cut Carbon Emissions to Prevent an Alien Attack

NASA Scientists have claimed that reducing our carbon emissions could prevent an alien attack. Extraterrestrials could view changes in the earth’s atmosphere as evidence that humans are spiralling out of control and decide to take pre-emptive action to wipe us out to ensure we don’t become a threat: ‘Humanity may just now be entering the period in which its rapid civilisational expansion could be detected by an ETI because our expansion is changing the composition of the Earth's atmosphere, via greenhouse gas emissions,’ a report states.
