growth in Europe by bringing new crops from

the Americas and started Europe's economic

shift towards capitalism. Colonization disrupted

ecosytems, bringing in new organisms like pigs,

while completely eliminating others like beavers.

for the united states of america, 1945 to 1964 was a time of high economic growth and general prosperity. it was also a time of confrontation as the capitalist united states and its allies politically opposed the soviet union and other communist countries; the cold war had begun.
