In a high mountain area in central Utah stands the world's oldest, heaviest and largest tree, Pando. And it's dying!
Pando means "I spread" in Latin and it's a name that makes sense. Pando is a big group of trees that all grow from the same roots(根). They look separate but are all joined underground by their roots. With all these roots joined, the whole group of trees can share water and food.
▲ . In summer, animals(mule deer and cattle) feed on the new leaves, making it difficult for the trees to grow. The number of mule deer has even increased because their natural enemies(mountain lions, bears) have disappeared. The second problem is from people. Hikers and campers like this area because of the colourful leaves in autumn. But getting too close and stepping on the new growth has made Pando smaller and thinner over the last 50 years.
Protecting Pando is challenging. Putting fences(栅栏) around it to keep animals away has helped new growth. But deer are smart, and they've found ways to get through the fences. Other efforts have included cutting or burning part of Pando to encourage new growth. Pando grows back very quickly after a forest fire, and these fires do not reach temperatures that would kill its root system.
Michael Grant, one of the scientists who helped name Pando, warns if the trees are in trouble, the whole ecosystem will be in danger too. We need to make people understand the long-term effects of our actions.
Dust storms(沙尘暴) appear when strong wind blows sand and dirt from a dry surface. Strong dust storms may cause deaths, so you should know how to protect yourself from dust storms when you meet them.
Be careful of dust storm warnings | Dust storms probably happen on hot summer days, and it's not safe for people to travel during this period. So you should listen to the local TV or radio before travelling, and consider changing or giving up your trip if dust storms are predicted(预测). |
Be prepared | If you are in a place where storms happen often, carry a mask(面具) to keep dust and dirt away from your face, and a pair of glasses to protect your eyes. |
Stay inside | Do not move around when a dust storm comes, as you will not be able to see hidden(隐藏) dangers. So if you are in a house, don't go out and just stay inside. |
Protect yourself from flying objects | Cover your body as much as possible in a dust storm. A strong wind of dust storms can carry heavy objects, so you should try to stay low, and close to the ground, and protect your head with your arms or a backpack. |
