Why are leaves falling off trees in summer?

The leaf drop is an adaptation that allows the trees to shed leaves in summer to reduce the potential for even greater water loss. The fewer leaves, the less water needed to keep them happy and the less water escaping from the soft leaf tissue.

Is it OK to leave leaves on lawn over winter?

Excessive leaf matter on your lawn going into winter is bad for several reasons. First, it will smother the grass and if not removed very soon in the spring it will inhibit growth.
