Probably because their plans to turn all Earth residents into vegetarians are not as successful as they initially hoped, PETA (People for the Ethical Treatment of Animals) are now turning their attention towards Mars.
Thus, this green-oriented group wishes that both the astronauts who are to visit this remote planet at some point in the future and the colonists who plan on inhabiting it opt for an environmentally friendly lifestyle and only feast on fruits, vegetables, seeds and the like.
Interestingly enough, PETA might in fact be on to something when stating that life on Mars can and should be 100% vegan.
This is because, as several researchers and scientists have pointed out, space exploration and raising animals for meat and dairy are two activities which do not really see eye to eye.
As previously reported, the food industry now up and running on our planet burns up significant amounts of both natural resources such as water and soil, and energy, all of which are pretty much lacking in outer space.
Huffington Post quotes some of the arguments brought forth by PETA in order to convince astronauts and Mars colonists to be vegetarians, which read as follows:
“The opportunity to colonize Mars means a chance to make a fresh start, especially now that we’ve degraded our own planet by treating our fellow animals like disposable widgets, filled the air with pollution that will soon make the sky in 'Soylent Green' look clear, and populated the Earth with so many humans that the premise of 'Logan’s Run' starts to look practical.”
Furthermore, “Ensuring that Mars is a vegan planet (rather than importing animal products from Earth or creating factory farms on our new home) would protect animals from the horrors that they endure in the meat, egg, and dairy industries.”
According to the same sources, PETA’s sudden interest in once again demanding that whatever groups of people make it all the way to Mars are vegetarians has to do with the fact that SpaceX founder Elon Musk has recently stated that the first Mars landing will take place within 5 years' time, in 2018.
