On July 17, 1942–February 2, 1943 the Soviet forces were holding off the Wehrmacht and Luftwaffe forces. In the battle of Stalingrad the Soviet Union introduced the new T-34 medium class battle tank which was a armored machine capable of impressing speeds outrunning almost every single German tank. T-34s were used against the German Howitzer tanks and Heavy tanks by shooting down their tracks and then going in circles around the tank slowly shooting it down. Another main reason why the Battle of Stalingrad was so important is the sudden turn of tide in the war as the Soviets succeeded in defending and pushing back the Wehrmacht forces from the city.
The Europeans began to colonize those regions and territories which are rich in resources because they need raw material for their factories to make the final product and sell those final products in new markets.
This led to Globalization and world economic connectivity, It led to the worldwide pollution and other sorts of disease especially cancer and global warming.
