小题2: ___________
Environmental groups say illegal turtle hunting is one of the major threats to endangered sea turtles in southern California and Mexico. It has been illegal to harvest and eat sea turtle meat in Mexico for more than ten years. However, demand for sea turtle meat is widespread in both Southern California and Mexico. Biologists believe that illegal hunting is one of the main reasons for the sharp drop in sea turtle populations during the past thirty years.
小题3: ___________
The week before Easter Sunday is an especially deadly time for the turtles. As many as 5,000 turtles are killed during this time each year. Many Mexicans and Mexican Americans eat turtle meat during the days before Easter. Many people do not eat meat during this holy time in order to obey the rules of Lent. Because sea turtles swim, many people consider them to be fish. Fish is permitted during Lent.
