For years, humans have fought with the dandelions(蒲公英). Most people consider dandelions as terrible grass for they can get in the way of the crops' growth. They pull them up by the roots or kill the plants against chemicals. But our war with the dandelions may be over soon.

It's no secret that the dandelion has its uses. Young dandelion leaves make a delicious salad. Dandelion plants have many long, thin roots, which allow water and air to mix in and keep soil healthy. Dandelion flowers also attract ladybugs(瓢虫). Ladybugs are good to have in gardens because they can eat small bad insects. However,most people still think of the dandelion as a wild plant. Their minds need to be changed.

If you pick a dandelion, you probably notice the milky juice that comes from the stems(茎). Dandelion juice is a natural source of rubber(橡胶). Around 30,000 different products are made from rubber today. Most of these products are made from rubber that comes from the rubber tree. But there are problems with these products. Some people have a serious allergy(过敏) to this kind of rubber. And a fungus(真菌) is killing out many of the rubber trees on our planet.

Scientists are looking for dandelion juice to become a good source of rubber in the future. Dandelions are easy to plant and grow quickly. People who are allergic to rubber products made from rubber trees are not likely to be allergic to dandelion rubber. When we make peace with the dandelion, we'll be planting it, instead of pulling it.
