Fifty years ago, the world's population was only about half of what it is today. Mankind once hoped to organize the imminent food crisis with the so-called green revolution. The rapid increase in the use of hybrid seeds and fertilizers has achieved some results, but mankind has also paid a heavy ecological cost. Statistics show that compared with the time our parents lived, the current global food production has nearly doubled, but the price is also huge; the consumption of surface water and groundwater by agricultural production has double.
The text is intended to illustrate that solving problems cannot be done at the expense of the ecological environment.
