1) The extermination of many species (plants listed in the Red Book) contributes to the reduction of biological diversity.
2) Drainage of swamps; as a result, many plants living in this biogeocenosis die.
3) The use of herbicides leads to the destruction of weeds, which in turn leads to diseases of other plants (since there is no competition)
4) Massive deforestation leads to the destruction of natural biogeocenosis, that is, other organisms (animals, fungi living in this territory) die along with vegetation.
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.
