Being alive, we all need fresh air, clean water, we all need fertile soil that is not poisoned by chemicals. Since we are alive, since we are in some way similar to a flower, a bee, a swallow, a crucian carp … it means that what is bad for them is bad for us. We are creatures of the same planet, we are relatives. All life on Earth needs help.
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.
