Isn't lift part of drag?

they make this statement:
The Dreamliner's wingspan is 197 feet, or about 25% longer than a
similar-sized plane, which increases lift and reduces drag.
I thought that lift, in addition to causing a net upward force on
the wing, also contributes to the drag force on the wing as well.
If this is the case then increasing lift should also increase
drag. Did I misunderstand?
The lift and drag curves for any given wing are a function of wing
design.
Although induced drag is a product of lift creation, the design of
the wing could easily change the lift and drag coefficients and
make the wing
more efficient.
These are complicated inter-relationships, and sometimes, when
doing an article in a non technical venue, a writer will simply
present the tip of
the iceberg.
This isn't necessarily wrong but you will probably notice a
distinct difference between an article on wing design written for
Fortune as opposed to one written for Aviation Weekly :-)

I think you can say more and explain less than anyone I have ever
heard.
Do you think the value of any writing can be most accurately
expressed by it's printed weight in pounds?- Hide quoted text -
Do you think you are achieving anything more than exposing yourself as
a rather tedious loser? Give it up man.
Cheers
No ****!!!!! What did I loose??
Marbles would be my guess.
