Why does everyone need botanical knowledge?

Botany studies plants. Plants need our attention to be maintained in the environment, because modern civilization interferes with their natural habitat. Just think about oxygen, can we live without it? Plants are the only source of oxygen on Earth. Secondly, it is energy for work. All humans, animals and other organisms (with the exception of a few bacteria) obtain energy directly or indirectly from plants. More than 90% (approximately) of the energy used on Earth comes from the sun. Only plants can convert this solar energy into chemical energy. Therefore, it is important to study botany.
