Industrial and agricultural work involves the use of many different chemicals that can run-off into water and pollute it. 1  Metals and solvents from industrial work can pollute rivers and lakes.  Pesticides are used in farming to control weeds, insects and fungi.
Nirvana fallacy. The nirvana fallacy is the logical error of comparing actual things with unrealistic, idealized alternatives. It can also refer to the tendency to assume that there is a perfect solution to a particular problem. A closely related concept is the perfect solution fallacy.
While that is certainly a worthwhile goal, many would argue that it is a bit empty on its own, creating this fallacy where one does not really exist. Exception: Striving for perfection is not the same as the nirvana fallacy. Having a goal of perfection or near perfection, and working towards that goal, is admirable. However, giving up on the goal because perfection is not attained, despite major improvements being attained, is fallacious.
