The bio threat of aliens is more real than ever!

In an article by Anthony Riccardi of McGill University, Canada
there are strong warnings about the dangers facing humanity. In
his opinion, extraterrestrial organisms can be delivered to Earth
from space and are a real threat to all biological life on our
planet.
Reported by SciTechDaily (https://bit.ly/3DDs8AQ). According
to Anthony Riccardi, the most vulnerable are the few endemic
species that are widespread, for example, on a small isolated
earthly island. Such species can be destroyed by alien
microorganisms that astronauts themselves or space tourists can
bring to Earth. In addition, the scientist believes that together
with terrestrial endemics, people will also have to protect the
alien organisms themselves, because they, too, are in danger after
they enter our planetary environment. Most likely, the cosmic
future of humanity will not be easy. However, it is unlikely that
earthlings will dare to retreat and stop space exploration.
