Your wish is granted. The sun is shining and it's also constantly snow weather. Most plants die. The remaining ones struggle. Also, there are no clouds. The snow just appears for no discernible reason.

 Now, I like snow, but I don't really like the sun. I'd much prefer it to be cloudy. I wish there would be clouds again. Lots of them! Enough to cover the sun most of the time. ...but not enough to kill the remaining plants. I like being able to breath.
