人类除了向大气层释放废气和微粒,还向自然环境倾泄垃圾。通常,这种垃圾对自然环境和人类本身都是有害且危险的。有害垃圾既有大工业大规模产生的,也有个人以较小的规模产生的。
In addition to releasing exhaust gases and particles into the atmosphere, humans also dump waste into the natural environment. In general, such waste is harmful and dangerous to the natural environment and humans themselves. Hazardous waste is produced both on a large scale by large industries and by individuals on a smaller scale.
