Aliens could end global warming or kill us

London, August 20 (ANI): US scientists claim that when aliens arrive, they will destroy Earthlings because we harm our environment so much.

Three scientists from NASA and Pennsylvania State University have warned that aliens would declare a war with us after they see how we kill other species and harm our planet by giving off greenhouse gases.

"Extraterrestrial intelligence (ETI) could attack and kill us, enslave us, or potentially even eat us," the report said.

"ETI could attack us out of selfishness or out of a more altruistic desire to protect the galaxy from us. We might be a threat to the galaxy just as we are a threat to our home planet," it stated.

However, there is also a possibility that aliens "could help humanity by solving hunger and disease," the Daily Star quoted NASA boffins at Pennsylvania State University, as saying. (ANI)
