Now our life is so happy that it is directly related to nature. The oxygen we live on every day is a gift from nature. So the existence of trees is closely related to people. And I believe many friends have seen some very tall trees when traveling. These trees not only thrive on their own perseverance, but also need careful artificial cultivation to make them thrive and become the towering trees we finally see.

Today, Bian Xiao told you about a very tall redwood tree. Its address is in Sacramento National Park, the capital of California. There is a very big redwood tree here. It is very tall. Seeing it is simply a feeling of towering into the sky. Because this tree is particularly tall, other trees look even smaller against it. According to statistics, the height of this tree is about 76.2 meters, and the trunk needs the arms of more than a dozen adults to barely surround it. Because of its huge height, this tree has attracted the attention of many local people.

Even in 1880, the local people realized that tourism could increase their income, and in order to increase the reputation of this giant tree, they dug a big hole under it, which was specially for coaches and tourists to watch. At the beginning of this tree, it was allowed to drive here. However, in order to better protect the annual rings of this tree, only pedestrians are allowed to walk under this tree. But because the trunk of this tree is stronger than others and the hole is dug deeper, it is called tunnel tree locally.

With the vigorous publicity of scenic spots, the fame of this tunnel tree has increased a lot, and the park has become more popular. Many people have traveled thousands of miles to see this tree. In order to attract more people, the manager of this tree park dressed it up for tourists to take pictures here as a souvenir.

Just a few years ago, because the western United States experienced many natural disasters, this tree did not escape these fates. Besides, the local park makes money by digging holes in trees, which hurts its foundation. Finally, it gradually became a weak empty shell. After a long time, the tree withered.

In fact, the park manager has never considered the life of this tree. If this tree is well maintained, its life can be extended for several years, so that the park can earn more money. Obviously, in order to make more money, the park dug a tunnel on it, which will definitely cause damage to the trees. This is where the interests of man and nature lie. You have destroyed the forest, and your interests have been damaged to some extent.
