With the heartbreaking photo of a Syrian child rescued from a bombed house making its way around the internet -- as well as our nonstop election circus -- it's time for some good news for a change.

The CDC reports that pregnancy in teens aged 15-19 has fallen by 46% from 2007 to 2015.

The CDC did not discuss the specific reasons for this decline. However, there are probably three major contributors:

First, it is known that teens are having less sex.

Second, use of the "morning-after pill" has skyrocketed from 8% in 2002 to 22% in 2013.

Third, there is a high rate of abortion among African-American teens.

The latter two reasons for the decline in teen pregnancy may be upsetting for some people, but the fact that teen pregnancy (which is linked to all sorts of societal problems) has nearly halved is reason for optimism.
