Is there a logical need for having a cold season?

I was always told a good cold winter cut down on bugs in the summer. 

"It lets people, in Phoenix, know how the "other-half" lives."

I get bored easily.  I crave change. 

I would hate the same temperature every day.  Move to Australia.  The mean Temp in Sidney is 75 degrees.

Yes.  It matters for roots and it kills off insects.  We don't get cold weather here and thankfully the insect problem is not bag.  I think that is from being on the ocean and away from the forrest.  Back home we had so many insects and mosquitoes in the Summer when we did 't have a long freezing spell in the preceding Winter. 

I told you an array of orbiting mirrors may be your solution.

Pest control...... It helps to kill off the wasps and scorpions here :)

Relief from the summer.

Yes, it gives people like me a much needed break from the summer. Let it snow! CHAAAAAAAAAAAAAAAAAAAAAAAMP!
