What unites all inhabitants of the planet Earth? Prove your point of view is correct.

They are united by the fact that they live on the same planet. You and I, together with all other people, like in a spaceship, are flying in black bottomless space on a small blue star – our planet Earth. If something happens to our ship – the planet, then one way or another it will affect all earthlings, each of us. Thus, living in the same space, we are connected with each other by invisible threads, we are dependent on each other. We depend on the mind of every earthling, on how much he understands the fragility of our world.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
