The global environment during the Last Glacial Maximum (LGM) and the implications for the perceived climatic change in the developing countries

Abstract

Earth’s environment is the home of mankind. The constituents are there as the provisions for man to live and be sustained. Naturally, the environment experiences changes (either hot warm or dry cold) which occur from time to time, every time, with varying degrees of the effects. The actions of man however, began significantly to influence such changes to occur and affect life rather too adversely even when the condition ought to be more favourable. For the Anatomically Modem Human (AMH) emerged in the hot warm period and has since had significant influence on the general condition of the environment. This influence especially since about 1950 has tended to change the situation of things within earth’s environment to the worse as it is now occurring quicker with more devastating effects on the existence of man, other organisms, and the entire rich constituents of the environment. Here, a note of warning is issued using the natural example of the LGM as has been documented in the earth’s ‘library’ and re-affirmed through prehistoric environmental studies. The LGM was evidently so devastating that some species of the world went into extinction while it lasted. But the reverse to the rosy hot warm phase, especially since the ‘Recent’ came as a relief particularly to the more vulnerable man. Man however, seems to have been extreme, experiencing this beautiful epoch of the Quaternary to his advantage. His limits are beginning to frightfully overshoot the boundary, to the detriment of the environment and the survival of especially humans with the boat being rocked to near capsize irrespective of nature’s navigatory itenary. This, he must act against, through more careful operation such as the suggested ‘management by avoidance’ means of operation in especially the developing countries areas of the world where this has not been put into real practice. Everybody therefore, should be meaningfully involved in the upkeep of the environment without the notions of hide and seek from some quarters.
