chaos theory

This man named Edward Lorenz came up with a theory of why not tell the weather for the future? not like tomorrow the future, but like next month! But while he was doing his studies, he found out that this was near to impossible. There is too many things that can change the weather, thus the butterfly effect. Not only that, but people do too many things to the environment to cause an inbalance in the weather/environment so their is no way to have an exact weather reading.
