(Cross-posted at The Times of Israel and zootorah.blogspot.com.) In the last few days, a devastating plague of locusts, numbering in the tens of millions, has been sweeping across Egypt. In Israel, the Ministry of Agriculture is on full alert. A special hotline has been set up, and the pesticides have been prepared. Hopefully, modern agricultural technology will help us avoid disasters such as that of 1915, when a plague of locusts in Israel led to much tragedy.
