Pollution is causing human penises to shrink, according to one scientist.

A leading epidemiologist (dịch tễ học) and environmental (môi trường) expert has published a book that examines the link between industrial chemicals (chất hóa học công nghiệp) and penile length (độ dài của chim).

Dr Shanna Swan's book, Count Down, argues that our modern world is altering humans' reproductive (sinh sản) development and threatening (đe dọa) the future of our species (tương lai loài người).

The book outlines how pollution (ô nhiễm) is leading to higher rates of erectile dysfunction (rối loạn cương dương), fertility decline (giảm khả năng sinh con), and growing numbers of babies born with small penises (chim nhỏ). Though the headline fact about shrinkage may sound like a laughing matter, the research paints a bleak portrait of humanity's longevity (tuổi thọ) and ability to survive.

"In some parts of the world, the average twenty-something today is less fertile than her grandmother was at 35," Dr Swan writes, dubbing the situation a "global existential crisis" in the book.
