In spring, you may have seen white foam(泡沫) on a green tree or other plants. As a matter of fact, the foam is where young spittlebugs(吹沫虫) live. These insects are protected by the foam, and they usually don’t do much harm to the plants.

As we all know, in late summer, a mother spittlebug lays her eggs on the plant. The babies will hatch(孵化) in spring. After they come to the new world, they begin to eat juice from the plant. The babies eat more juice than their bodies need for food. The extra juice mixes with a special waste that the spittlebugs produce. When this fluid(液体) is released, it mixes with the air, forming bubbly foam.

What is so great about having a foam home? The space inside is so wet that it can keep the bugs’ soft bodies from drying out. And the foam tastes bad, so it keeps away most animals that would eat the bugs. Some birds will reach their heads through the foam to find the bugs. Wasps and ants might eat them, too. But most of the bugs stay safe inside the foam.

Once the bugs have grown into adults, they stop making foam. They leave their homes and jump from plant to plant in search of food. The adults look a little like tiny frogs. For this reason they are also called froghoppers.

If you see some foam on a plant, you might want to take a careful look inside. Gently push some of the foam aside with a small stick. Deep inside you may see a few insects eating plant juice. They might also be making more foam. Be sure to push the foam back after a moment to cover the insects and keep them safe. Soon the spittlebugs will grow up and leave their foam home. They will join the other insects in the grassland.

Have you ever wondered where the chocolate in your favorite candy bar comes from? Choco-

late comes from the cacao tree, which grows in warm, tropical areas of West Africa, Indonesia, Malaysia, Mexico, and South America. And who eats the delicious chocolate made from the cacao grown in these places? The majority of chocolate is consumed in Europe and North America. This probably sounds like a familiar story-developing countries produce inexpensive raw materials that are manufactured and sold as finished goods in developed countries, and generally, that is what happens with chocolate. Large chocolate companies buy cacao beans at a low price and produce cocoa and chocolate products to sell at a relatively high price.

But the familiar story has a new chapter. Beginning in the 1980s, some consumers learned that cacao farmers were living difficult and uncertain lives. The farmers received money for their crops based on world markets, and the market price for cacao was sometimes so low that farmers received less for their crops than the crops had cost to produce. In response, groups of consumers in Europe and the United States developed "fair trade" organizations to guarantee that farmers of cacao, as well as coffee and tea, would receive fair and consistent prices for their crops.

Fair trade organizations benefit farmers by buying cacao beans or other products from them directly at higher-than-market prices and eliminating（消除）“middle men" such as exporters. Fair trade organizations also encourage farming techniques that are not harmful to the environment or to farm workers. for example, growing cacao without chemical pesticides or fertilizers in the shade of rain forest trees.0ne organization, Equal Exchange, helps farmers set up farming cooperatives in which they can share resources and work on projects such as community schools. Another, Fairtrade Labelling Organizations International(FLO),guarantees that products bearing its label meet standards that improve the lives of growers and producers.

The results of fair trade are a better standard of living for some farmers and nicer chocolate bars made with organically produced cocoa that consumers don't feel guilty about buying. And al- though fair trade chocolate is somewhat more expensive than other chocolate and now makes up only 1% of chocolate sold, the fair trade idea is spreading quickly. You may soon see fair trade chocolate right next to the more famous bars in your favorite store.
