Seven Billion - The City Solution

"Per capita, city dwellers tread more lightly [...] Their apartments take less energy to heat, cool, and light than do houses. Most important, people in dense cities drive less. Their destinations are close enough to walk to, and enough people are going to the same places to make public transit practical. In cities like New York, per capita energy use and carbon emissions are much lower than the national average."

select vs select_tag vs collection_select

Love the simple, rules-of-thumb write-up on which to use, when.

"Use select when you require a basic drop-down selection box populated
with data not sourced from a database."

"Use select_tag when you require a drop-down selection box populated
with data not sourced from a database, and are happy to hard code the
default selected option tag."

"Use collection_select when you require a drop-down selection box,
whose source is a model/object."
