Yes, what's up! Here we go. Climate change and ozone depletion affect one another in complicated ways. In simple terms, "the ozone hole" pertains to the Southern Hemisphere. However, reductions in ozone content in the stratosphere above the Arctic have been recorded during the northern winter untill early spring (January through March) in recent  years. These reductions, about 20-25%, are much smaller than those measured in each southern spring (September through December) over the Antarctic ozone hole, the big one.

Bacteria are abundant in soil, water, and air as well as in the depths of the Earth's crust, organic matter, and live animals or plants. They are also abundantly social -- among themselves and with others. Not only do they interact with each other but also with their host. Bacillus subtilis and Streptomyces coelicolor are two examples from daily life. The former would be involved with the ropiness of spoiled bread. But the well-known Streptomyces produce the soil's earthy aroma and flavor and the majority of today's antibiotics.
