Why are environmental problems common in developing countries?

With the development of their technology, their industries, factories too are ssubjected ro new trends. thereby, the factories emmit more and more gases and liquids out into the environment without proper planning. And also sewage disposal and proper garbage dumping is not properly planned.

The economic system prevailing in those countries is not stable. Therefore proper understanding about the environment is not very well seen. Mechanization is also been used as a new trend. Therefore the relationship between man and machines take root. Machinery is used more. THEREFORE IT IS NOT ENVIRONMENT FRIENDLY.

The changes to agriculture in the united states since 1900 is that increased mechanization has increased food production, thereby increasing the need for labor. there has been an increased need for higher speeds of food production due the fact that the population in the united states continues to rise.
