The chemical struggle

Secondarily, the collateral effects caused by these poisons, like pollution of the atmosphere, the water bearing strata and water, which degrade only after a significant period of time cannot be ignored.
Added to this is the fact that many of these substances are extremely toxic for the people who come into contact with them when they are produced as well as when they are used on crops and when agricultural products are consumed. It is, therefore, easy to understand how the impact that these poisons may have on the ecosystem has now become one of the major worries for many governments, who have set up support programmes for the use of alternative techniques.
