The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another.
In a broadcast network, routing is not needed. A transmission from any attached station is received by all other attached stations.
Other functions,such as sequencing, flow control, error control, can be done at layer 2. The MAC sublayer is responsible for addressing across the LAN. With the Data link layer and its sublayers (MAC & LLC), no network layer is needed.

Gases in atmosphere causes break in ozone layer?
There is no actual break in the ozone layer. The "hole" is an annual event above the poles caused by the lack of sun reaching the ozone layer. CFC's are believed by some to cause a contributing change in this layer. The lagest "hole" recorded occurred decades before CFC's were created. The primary cause for ozone is lack of sun, not any gas.
