        <p class = "intro">Overall, the global demand for meat is growing, but at different rates in different re- gions. In Europe and the United States, the biggest meat producers in the 20th century, consumption is growing slowly, or is even stagnating. On the other hand, the booming economies in Asia and elsewhere, will see around 80 percent of the growth in the meat sector by 2022. The biggest growth will be in China and India because of huge demand from their new middle classes. </p>

	<h1 class = "header">The Meat Demand Gap Between Two Worlds </h1>
	<p class = "intro">Overall, the global demand for meat is growing, but at different rates in different re- gions. In Europe and the United States, the biggest meat producers in the 20th century, consumption is growing slowly, or is even stagnating. On the other hand, the booming economies in Asia and elsewhere, will see around 80 percent of the growth in the meat sector by 2022. The biggest growth will be in China and India because of huge demand from their new middle classes. </p>
