Read the following article and answer the question. Article: The next time you eat a piece of chocolate, be sure to enjoy it, because according to two of the world's largest chocolate makers--Mars Inc and Barry Callebaut, the treat may soon be in short supply. The problem? We are consuming the candy at a faster pace than farmers can grow cocoa. The manufacturers say that in 2013, people consumed 70,000 tons more cocoa than was produced. Experts say that this is the worst supply-demand imbalance they have experienced in more than 50 years. Parts of the reason for the condition is the large reduction in supply, caused by a continuous drought in the west African countries of Ivory Coast and Ghana, where more than 70 percent of the world's cocoa is produced. Additionally, a certain disease known as frosty pod has destroyed 30 to 40 percent of global cocoa production. As a result, many farmers have turned to more profitable and easier grown crops like corn. This means that even if conditions improve, cocoa production may never get back to normal. Meanwhile, the world is only getting hungrier for chocolate. The biggest increase in demand is from the residents of emerging market countries like India. Though their consumption is nowhere close to the amount European devour, their newly acquired amount for the treat , is making a huge dent in an already tight market. There is also the growing desire for dark chocolate, which contains more than 70 percent cocoa compared to normal chocolates. Experts believe that if consumption continue at this pace, cocoa deficits could swell to one million tons by 2020 and to an even more worrisome, two million tons, by 2030. Not surprisingly, cocoa prices have risen by 60% since 2012, a cost that manufacturers have offset by raising the prices of everyone's favorite candy. As the situation worsens, the price of chocolate can only rise--so be sure to enjoy piece of the sweet treat, like it is your last! Question: According to the author's prediction, we can know that_.
