人类是地球发展到一定阶段而产生的。在亿万年的发展中,人类与其生成的环境,互相制约,互相依存。当自然和人为的因素,包括人类改造自然的斗争,如实现工业、农业、国防、科学技术的现代化过程中,人类改造了环境,同时也破坏了环境。比如工业发展的过程中,产生“三废”(废水、废气、废渣),农业发展过程中,农药、化肥的残毒问题,造成对环境的污染。 Humankind is generated by the development of the earth to a certain stage. In the development of hundreds of millions of years, human beings and their environment are mutually restrained and interdependent. When natural and man-made factors, including the struggle of mankind to transform nature, such as the modernization of industry, agriculture, national defense and science and technology, mankind has transformed the environment and destroyed the environment at the same time. For example, in the process of industrial development, “three wastes” (waste water, waste gas, waste residue), residues of pesticides and chemical fertilizers in the agricultural development process are caused, resulting in environmental pollution.
