An enormously influential biological exchange occurred when Europeans landed in the Americas, to the benefit and detriment of Europeans and Natives. Old World—New World plant and animal exchange resulted in sugar and bananas crossing the Atlantic while pigs, sheep, and cattle arrived in the Americas. The transfer of European diseases had catastrophic repercussions: influenza, typhus, measles, and smallpox devastated the Native American population. The Biological Exchange (also called the Columbian Exchange or Grand Exchange) is one of the most significant biogeological events of world history, affecting almost every society on earth and historians have only recently begun to question the event and the way it has been traditionally interpreted. In the traditional interpretation of the Biological Exchange, Indians lived in harmony with their environment in a pristine world and both the Natives and the environment were suddenly devastated following the arrival of Europeans. Biological exchanges of plants and animals enabled a better and longer life for Europeans, who took food items like potatoes and corn back to the old world were suddenly able to grow food to support their large population while reducing the population overgrowth by transporting humans to the new world.
Invading Russia proved disastrous because of a few reasons:
1) Timing of invasion: While France invaded towards the middle of summer (the best time is summer), it just wasn't enough time to take over the strategic areas before winter set in, leading to the French defeat and eventual retreat from Russia.
2) Sheer size: Russia stretched across Eurasia, and because of this large extent covering thousands of square miles, Napoleon had a hard time locating and decisively taking over the land and guarding it, which led to infiltration, sabotage, and spies from the Russian empire.
