For years, people fought against the dandelions. Most people thought dandelions were weeds because they could stop the crops growing well. But our war with dandelions may be over soon.
Dandelions have their uses. Young dandelion leaves can be made into a delicious salad. And dandelion plants can keep the soil healthy. Ladybugs are interested in dandelion flowers. It's good to have ladybugs in gardens because they can eat small bad insects.
If you pick a dandelion, you'll probably notice the milky juice from the stem. Dandelion juice is a natural source of rubber. Around 30,000 different kinds of
products are made from rubber today. The rubber comes from the rubber trees. But some people may feel sick after using this kind of rubber. And the rubber trees are not easy to plant.
Scientists want to make dandelion rubber in the future. Dandelions are easy to plant and grow quickly. People will not feel sick after touching things made from dandelion rubber. We can make peace with dandelions: We'll plant them instead of killing them.
