Famine is a more complex problem than a shortage of things to eat; it is a challenge of market and distribution, the result of a long, slow decline in access to food. That decline may occur for any number of reasons, including natural disasters, politics, repressive governments, and poor management of resources. The famine cycle may be triggered by a natural disaster, but is often exacerbated by man-made issues, such as reduced wages and/or rising food prices.
There are several factors that can influence chemical reaction rate. In general, a factor that increases the number of collisions between particles will increase the reaction rate and a factor that decreases the number of collisions between particles will decrease the chemical reaction rate.here are several factors that can influence chemical reaction rate.

Many things lead to an increase in the rate of chemical reactions. These factors include: - Addition of Catalysts - Light (only in some reactions) - Increase in temperature -â¦ Increase in Pressure - Increase in amount of reactants.
