<h2>EXPLANATION:</h2>
<h3>Modern monoculture requires vast amounts of rain for irrigating crops as moisture retention is limited in the soil. A lack of topsoil also increases rain runoff. To achieve this vast amount of extra water it means draining from lakes, rivers, and reservoirs, which is exhausting natural resources and aquatic ecosystems.</h3>
