Answer:
The wastes or run off of the industrial farming enters the water and nearby cultivated crops, this waste consist of chemicals and pesticides mostly, that are the cause of destruction of not only the cultivated crops but also the useful soil-borne rhizoshpere bacteria too. On the other hand climate change impacting from emission of greenhouse gases, increase air pollution and also cause deforestation. Such circumstances could all lead to the extinction of important crops.
In order to avoid these problems, proper waste management systems should be developed to dispose the waste of industries and others at area that is far from the population or cultivation. The climate change resulting from the pollution could be avoided by the use of filtered products for the smokes, so that filter could absorb harmful substances and the smoke released in air would not be that much toxic. Moreover, there is the need to identify and grow such crops that can adapt these environmental changes.
The four biological macromolecules are carbohydrates, lipids, proteins and nucleic acid. These macromolecules are known as polymers and are built when <span>monomers </span><span>join together by a process known as the dehydration reaction. The dehydration reaction is a chemical reaction that produces water (H2O) and the result is the covalent bonding of the two monomer molecules. The monomer molecules consist of nutrients found in the soil, as in the case of plants, and the intake of food as in the case of animals. </span>
