For years, the Earth has suffered from large-scale emissions of greenhouse gases and pollution. This could cause alien civilizations to destroy us to prevent and preserve Earth, for the next ones.
This theory is based on the analysis that some more advanced civilizations could have caused to the planet.
Is it possible that extraterrestrial civilizations consider us a serious threat, especially regarding the existence and preservation of other races in space? Could they take drastic measures against humanity?
For us, this scenario is entirely possible after first contact is made.
Observing the planet, aliens perceive changes in the Earth’s atmosphere as a clear sign of a civilization that is growing rapidly, aggressively and is already out of control. This could prompt them to take drastic action to stop us from becoming a far more serious threat.
Obviously, this theory carries with it a number of proposals to prepare humanity for such contact.
We certainly need to be careful with signals sent into space, especially those that provide compromising information about human biology.
With this information, they could design weapons such as “biological bombs” from viruses unknown to us to attack us. Faced with any kind of extraterrestrial contact, only specific topics should be discussed until their intentions are known.
It is possible that their mission is attack or enslavement. This includes even those peaceful aliens who happen to carry an unknown disease to humanity that can be deadly.
Hostile aliens would be wary of rapidly expanding civilizations. This is because humanity has caused the extinction of tens of thousands of species on earth. Another reason to think that the ideal scenario for the settlement of other civilizations would be the complete destruction of humanity.
A pre-emptive strike would be particularly likely in the current stages of our development. A civilization can become more and more difficult to destroy as it continues to develop and in parallel changes the composition of the Earth’s atmosphere through the emission of greenhouse gases. Thus we ourselves will be destroyed, but the planet will not survive.

Perfect planets for developing biological species like Earth are rare in the universe. The fact that we humans do not value our home does not mean that other extraterrestrial civilizations will use it in the same way.
These scenarios give us reasons to limit our development and growth and reduce our impact on global ecosystems. It would be especially important for us to limit greenhouse gas emissions, since the atmospheric composition can be observed from other planets, whose populations can take action at any moment.

Although until now there is no official report of established contact with extraterrestrial life, our theory shows that the likely scenarios that contribute to the future development of humanity should be taken into account. If we avoid the impending catastrophe and collapse of the planet, it is possible to achieve our long-term survival as humans.
