When 'Want" is Confused with "Need" the Supposed Beneficiary Becomes the Victim.
We MUST obtain this data
We NEED to display this animal in captivity
I MUST preserve my culture
We MUST make our beaches safe
We MUST understand these animals to protect them
We NEED this data to protect them
Each of the above are choices rather than needs or musts. When choices are misconstrued as needs these choices become excuses to do what we want, not what we need to do. Let's see if I can defend this notion and for fun I'm going to do it from two perspectives; scientific and extremist.
Public Safety: Let's start with politicians who state that we MUST take preventative action against shark attacks, whether this is referring to shark culls, beach nets, gill nets etc.
Science: We NEED to understand these animals. We NEED to see them give birth. We MUST tag them to protect them. We MUST know its complete life-cycle, solve their puzzle, etc., etc., blah, blah, blah.
