Infrastructural damage caused by rising sea levels, fires, droughts and many other disasters takes a toll not only on buildings, homes and schools, but also on forests, jungles and other natural environments. Just like animals, humans are and will be forced to leave their homes. Economists and scientists predict that huge migrations of people will lead to a loss of productivity and security, necessary conditions for the economic stability of any country. Those who have studied these fluctuations say positive changes must happen quickly if we are to avoid massive economic instability on a global scale. Yet as humans we see things in the short term, this will eventually have to change if we are to prevent global warming or other major problems.
