Explain why some economists believe that carrying capacity is generally increased by:
a) technology
b) trade

Technology has allowed humans to experience more efficient travel from place to place. People could travel all over the world with the help of a plane. Because of the increase in technology, people can now easily carry goods from place to place. A large amount of our produce, or the produce of other countries, can now be shipped all the way across the world. This increase of transportation and goods can now allow the population to increase.
