Here is a quotation from Baha’ullah, from a pamphlet put out by the Baha’i community of South Africa in 1999, called Who is writing the future: Reflections on the twentieth century. P. 2.
” Strange and astonishing things exist in the earth . These things are capable of changing the whole atmosphere of the earth and their contamination would prove lethal.”
A warning that would have been made in the 19th century, and unfortunately how true they are turning out to be.
