Hello friend,
I presume that Americans developed a "tradition of waste" because of how easy we have made things to do. For example we have made food so easy to get that it makes us lazy therefor making us not care if anything gets wasted.
Hope I helped!
In the late 1500s the council of Trent was led by a group of Catholic Cardinals. These catholic cardinals wanted to reform the church.
-Hope that helps u out!
