Extremely harmful to people if it comes in contact
It is used on vegetables fruits tobacco cotton and other farm crops similar to these.
Reflection
Is the reason for using the molecule good enough to justify the use of that substance?
Yes and No It is good because it keeps the insects off of our
food It is bad because if it comes in contact with us it can
be really harmful.
