Ở nước ta, hàng trăm ngàn nạn nhân chất độc da cam đã chết. Những người còn sống đang hằng ngày, hằng giờ vật lộn với những căn bệnh quái ác bởi dioxin mà hình như y học bất lực. Họ sống trong đau khổ tột cùng cả về thể xác lẫn tinh thần, chết dần chết mòn và chết tức tưởi. Dioxin gây nên chứng vô sinh ở nam giới, làm cho nhiều gia đình, dòng họ có nguy cơ mất nòi giống. Dioxin gây biến đổi gen, làm cho thai nhi chết yểu hoặc phát triển không bình thường. Bao bà mẹ chín tháng mang nặng đẻ đau, nhưng đau khổ suốt đời vì sinh ra những “giọt máu” không lành, những đứa con tật nguyền vô phương cứu chữa. Đó là những đứa trẻ hoặc thiếu hoặc thừa các bộ phận cơ thể, hoặc đủ nhưng bị biến dạng, mất khả năng hoạt động: tai không thể nghe, mắt không thể nhìn, miệng không thể nói, chân không thể nâng bước, tay không thể ôm ấp, não không thể tư duy… Đó là những đứa trẻ câm, điếc, tâm thần, bại liệt, nhũn não, sống đời sống thực vật.
