It has killed more than 80 million trees worldwide, mainly in South Africa since 1910, Argentina (10 million) and Brazil (6 million) since 1970, and the U.S. (3 million) since 1950. With the spreading of T. citricida the severity and impact has increased dramatically in Central America and the U.S. In Spain there has been a progressive decline in production from over 40 million sweet orange and mandarin trees.

“The child thinks of growing old as an almost obscene calamity, which for some mysterious reason will never happen to itself.

Only child life is real life.”
