There are several factors that may lead to people becoming refugees, including warfare, political instability and natural disasters such as floods, tsunamis and famines. Refugees are defined as people who must leave their homes or native areas for reasons of safety and survival.

Answer:
One example is the agricultural progress developing farming methods to allow humanity to meet its needs.
The Industrial Revolution, which had humanity using machines to work over the environment to gain manufactured products.
The Technological revolution had an impact on communication (computers, internet), health care, and many areas that improved the quality of life in a vast and sometimes dangerous environment.
Finally, pollution and the climate change examined from the perspective of environmental possibilism has led to experiments on built environments with reasonable management of waste that shows how pollutants can be transformed into less dangerous materials.
Explanation:
Environmental possibilism is a theory that claims that the environment only limits the number of choices for human behavior since humans have agency and have power over the environment within certain limits and are as well responsible for their doings.
Answer:
Eratosthenes lived in the city of Alexandria (northern Egypt) and he knew that the Sun was never directly overhead at this location, even on the Summer Solstice. However, he knew that on Summer Solstice, in a town located in southern Egypt and named Syene, there was no shadow at the bottom of a well. This meant the Sun was directly overhead in the town of Syene at noon just on that day.
So, taking into account the sun is radiating to both places at the same time, but in Syene there is no shadow and in the second place,Alexandria, a shadow is observed, the logical explanation Eratosthenes concluded is that this must be a <u>curved surface. </u>With this in mind, Eratosthenes calculated the circumference of the Earth.
Therefore, if the Earth were flat, at both places the shadow would have been the same, and the calculation of the curvature of the Earth would have not been possible.
