ABSTRACT
The dramatic consequences of human activities, which have been happening since the beginning of the Industrial era through population increase, sprawling urbanisation and polluting industrialisation, transportation and food production activities, started to take their toll on the planet during the post-industrial era. Perhaps the greatest inventors of all time were the prehistoric people of the pre-industrial era. Early homo sapiens originated in the first part of the Stone Age, which is the Palaeolithic or Old Stone Age. The Bronze Age refers to a period between approximately 3300 and 700 bc, when the most advanced metalworking, at least in systematic and widespread use, included techniques for smelting copper and tin from naturally occurring outcroppings of ores, and then combining them to cast bronze. The Iron Age stretched from approximately 1200 bc to ad 800. In European history, the Middle Ages, also called as the Medieval period, lasted from the fifth to the fifteenth century.
