Due to two factors..
The first factor is the placement of Europe in relation to latitude lines.
Up north is bound to be more cold than most places down south near the Mediterranean sea. (Which is closer to the equator)
The second factor is the physical geography of the region. Ranging from mountain ranges like the Alps and the Urals to the flat planes of much of mid Europe. The weather interacts with these regions and determines the climates making up much of the continent. (Only takes a rudimentary understanding of basic earth science and geography to understand that. If you have more questions pertaining to the subject, pm me.)
Some of the cash crops that were grown in the caribbean were sugar, tobbaco, coffee, spices, and cotton. :/
Humans affect the physical environment in numerous ways: overpopulation, contamination, burning fossil powers, and deforestation. Changes like these have triggered climate alter, soil erosion, poor air quality, and undrinkable water. These negative impacts can influence human behavior and can provoke mass migrations or battles over clean water.
