I am verifying the answers generated by an automatic system to the following question: what causes destruction of the ozone layer
Suggested answer: Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth 's stratosphere (the ozone layer ), and a much larger springtime decrease in stratospheric ozone over Earth's polar regions.
Should I validate this answer?
