So if you want to avoid the Sixth Mass Extinction, here are the top 10 things you can do. 1. Spread the word, to your family, friends, co-workers, and social media circle: the extinction crisis is real.
In Australia and New Zealand, summer officially begins on 1 December and ends on the last day of February (29 February on a leap year, 28 February otherwise).
I am sorry but your contention that the first day of spring is the equinox, the first day of summer the solstice, etc., simply is not true. The so called beginning of summer (the summer solstice around June 21st) and the end (the equinox around Sept 21 or 22) is merely the astronomical beginning and end of summer, nothing more nothing less.
