Hydroponic farming refers to cultivating plants without soil. Terrestrial plants can grow with their roots solely in a mineral solution, or the roots may be supported by an inert medium such as perlite or gravel. The farmer’s plants might have been failing at the same rate since some plants require soil, or perhaps the roots were simply too long.

Industrial farming practices have harmful ecological impacts due to the use of fertilizers and processed animal feed. The fertilizers contain toxic chemicals that might not appear on the plants, as their primary role is to eliminate pests. The real harm occurs when fertilizer particles dissolve in water and seep into the soil, contaminating the water table. This results in the water that was once clean becoming tainted. The build-up of various pesticides can lead to the death of aquatic life and even affect humans. Furthermore, over time, it can degrade soil quality by reacting with other soil components to form toxic substances.
