What are some of the dangers associated with the use of organophosphate pesticides that might be of concern for humans? (Organophosphates inhibit acetylcholinesterase.) What are some ethical concerns related to their use?
What will be an ideal response?
There are many insecticides that prevent insect pests from damaging favorable plants or household foods. The organophosphate insecticides kill insects by inhibiting acetylcholinesterase, the enzyme that degrades acetylcholine. This causes acetylcholine to accumulate and continuously stimulate in the synapse. These pesticides have a similar effect on humans.
The following are some of the ethical concerns: (1 ) Organophosphates could be used against humans in warfare. (2 ) Organophosphates could pose a threat to wildlife, including "good" insects such as bees, if not applied carefully. (3 ) These toxins could be used in homicides and suicides. (4 ) Accidental poisoning of farm workers and others exposed to these pesticides kills 500,000 people annually worldwide.
