The vast pollution which occurs globally can have a significant impact on air quality on a local scale. The reason for this is quite simple: polluted air can easily get trapped beneath a cloud cover, or be literally "blown" away to other locations, and when much polluted air gets accumulated, it can have devastating heath effects on a local population, not just to humans, but to animals and plants as well. Overall, the vast global pollution can effect the smallest of regions on an unprecedented scale.
The relationship of the earth and sun and their influence on the biodiversity of the planet at a global scale is quite directly related to one another as he changes in any one system will definitely lead to changes in other systems this is quite a sensitive to the axial parallelism.
Climate change and global warming are one of the biggest examples to prove this type of changes taking place around the earth and atmosphere of earth as the planet warms quickly due to human activity the patterns of land and oceans fluctuates continuously.
This, in turn, affects the biogeographical realm on the earth and hence the ecologically sensitive zones are destroyed and harmed due to the man's impacts that further remove away the protective layer that supports and surrounds the earth from outside effects of sun rays and in turn disturbed the parallelism.
Rotational tilt is the same as it used to be but the global climatic pattern is becoming harsher on biodiversity of the planet as it is now losing its resource wealth.
