Answer:
Ever since Columbus set foot in the Americas, the number of endemic species, that is to say, species that only live in a specific geographical area has diminished, while other species have thrived, in the five continents.
For example, the Columbian Exchange led to the cultivation of a South American crop: the potato, across Europe and Asia, where millions of people in cold climates where able to avoid famine by feeding themselves with it.
Another biological homogeneization process occurred with disease vectors: before the Columbian Exchange, diseases such as measles or smallpox were unheard of in the Americas. When Europeans arrived, Native Americans did not have defenses against this illnesses, and the majority of them perished because of contagion (over 90%).
Nowadays, these diseases are present all over the world, but thanks to vaccines, they do not kill as many people as before.
It's somewhat a matter of opinion, since many people have their favorites and it always looks good if you answer "Nelson Mandela". The truth is that after WW 2, the world got divided into a "Western" bloc under US leadership and a Communist bloc under the Soviet Union. The various US Presidents and Communist Party Secretaries all shaped the world in the Cold War era. A good candidate however is Soviet party leader Mikhail Gorbatchev, who practically single-handedly dismantled the old Soviet Union and thereby ended Communist rule over many eastern European countries. Americans tend to thank Ronald Reagan for that, but that is vastly overrating his actual influence on affairs. We Westerners like Gorbatchev for that, but in Russia he is generally seen as a weak leader and the man who 'sold out' Russia's global power and prestige and who was responsible for much of the following unrest until "thank God" Vladimir Putin took firm control and put Russia back on the map again.
