We buy cheap bootleg DVDs and fake Coach purses from random street vendors with little hesitation. But what about buying your daily medication from them, too?

This is a common practice in the developing world. In Zimbabwe, for example, street vendors offer the poverty-stricken populace medicine for a price five to eight times less than a legitimate pharmacy.

The trouble with these cheap meds is that they're often not the real thing. One study cited by the World Health Organization says the counterfeit medication industry could reach $75 billion by 2010. Although the industry's reach is worldwide, it's more prevalent in developing countries. The WHO says "many countries in Africa and parts of Asia and Latin America have areas where more that 30% of the medicines on sale can be counterfeit."

Though buying counterfeit medications can save a lot of money, it is also very risky. In 1995, 89 Haitian children died from taking counterfeit cough syrup that contained the active ingredient in antifreeze instead of the real medication. Governments in the developing world often lack the resources to track and prosecute these illegal manufacturers and sellers. The Internet is only making the fight harder.

Major pharmaceutical companies are protecting their products from counterfeiters using different methods. Today, companies like GlaxoSmithKline use holographic labels or stickers to make their product more distinguishable from fakes. Recently, counterfeit drugmakers have, however, been able to convincingly duplicate many of these stickers and packaging. For example, one study revealed that about half of Southeast Asia's supply of the anti-malarial drug Artesunate was counterfeit despite holographic packaging.

The easiest and fastest way to decrease the market for these fake drugs is for consumers to increase their own awareness. Many news organizations have begun to help. In this video, Al-Jazeera reports on counterfeit drugs in Mauritania.

Throughout the past 40 days, South Koreans have vehemently opposed a government proposal to lift a five-year suspension on the import of U.S. beef. Fear of meat tainted with mad cow disease prompted 100,000 Koreans to take to the streets of Seoul. Korea suspended the imports in 2003 when the first case of mad cow was discovered in American beef.

The public outcry over the proposal to lift the ban is President Lee Myung Bak's first big challenge as he tries to improve relations between the U.S. and South Korea. Though the president and his administration took office in February, already the uproar has prompted the president’s entire cabinet to offer their resignations. The divisive trade deal and a trucker’s strike over the surging price of fuel could further slow the South Korean economy.

This Al Jazeera video shows some of the more striking images from the demonstrations and gives an overview of the political climate that has led to the near- daily protests.

Some at the UN Food Summit are suggesting a second green revolution is needed to curb soaring food prices. “The underlying problem is the decline in agricultural productivity growth," said the UN's Lennart Bage. "Unless we reverse that, we’ll be back in the same situation in a few years' time.”

The first Green Revolution transformed developed-country agricultural practices from the 1940s to 1960s and led to increased production. Huge investments in seed research, infrastructure development and technological advancements fueled this transformation.

Increases in output are especially needed in Africa, which is in dire need of updating its farming techniques, improving agricultural technology and increasing the biodiversity of crop output. According to The Economist, several countries at the Summit promised to meet these needs by investing in seed research, building irrigation canals, and promoting the use of fertilizer.

Regulation reform and infrastructure upgrades are also needed. The International Food Policy Research Institute recently released a report saying prices could be cut if governments enforced market regulations. They also suggested African governments should dedicate 10 percent of their budgets to agriculture, and improve poor roads that hinder farmers' ability to get their crops to market.

However, Financial Times points out why a green revolution in Africa may not be easy to pull off. It would most likely require the cultivation of genetically modified crops in a region where many countries have resisted GMO foods. Other concerns involve Africa's diversity of climate and landscapes — farming techniques that work in some places might not work in others. Increasing output would also mean huge investments in irrigation systems. A dependence on rainwater and a lack of irrigation infrastructure has hindered many small farms in Africa.

The first Green Revolution took years to increase agricultural output in developing countries. It may be needed, but engineering a second Green Revolution is a daunting task.
