The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The Chemical Industry has helped to revolutionize farming - dramatically increasing overall production because the Chemical Industry has created all kinds of fertilizers, nutrients for the soil, insecticides, pesticides, herbicides, and fungcides. All of these artificial chemicals have helped the farming activity to better control plagues, and improve the growth of agriculture worldwide.
However, all of this comes with a price. Scientists have found that these chemicals can also damage the environment and pollute the waters of planet earth. So there have been debates about the use of these chemicals versus the possibility to use organic fertilizers or herbicides to respect and protect the environment.
