 * New foods, from the Americas, with higher nutritional value, increased the overall birth and survival rates, and increased the amount of healthy births.
 * Trade with the East and other parts of Europe helped spread different types of medicine to decrease the rate of death.
 * The increase of birth rate and the decrease of death rate caused the population to rise exponentially
 * The trade of syphilis from the new world to the old caused several more deaths and increased the death rate in Europe. No medicine and protection were invented at the time.
 * The trade of alcohol caused several health problems in the natives because they were not used to it and had very low tolerance.
 * There was new trade of food from Europe and animals, which helped complete many peoples diets, increasing the standard health or standard of living
 * The Europeans traded guns to the natives, but they weren't as technologically advanced, so the Europeans still had first priority. The new weaponry caused more deaths.
 * Trades of diseases such as smallpox, malaria, and syphilis caused the natives to die rapidly so that only 10% of the original population remained.
 * Trade in Asia stayed the same. They traded tea and silks to Europeans, which had neither a positive nor negative effect on the population growth on either Asia or the Americas.
 * Europeans traded Asians to the New World as a result of the cotton plantations and the epidemic diseases that killed many African slaves.
