Man makes attempts to correct his own mistakes. Due to the anthropogenic factor, many ecological zones, ambient temperature, radiation level and much more have been changed. This primarily threatens us ourselves. The biosphere will be able to update and recover. Every hour, three species of animals and plants disappear without our “help.” A man tries to intervene in these processes and protects some species, creates reserves, hunting bans. But the main and most important thing that is being done is installing treatment facilities that reduce the amount of emissions of hazardous substances into the biosphere.
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.
