4 . The best spring destinations in Tibet

The Qinghai-Tibet Plateau has long been an ideal and mysterious destination for visitors. Now with the arrival of spring, the climate is becoming more pleasant and Tibet has become an even better trowel destination. Here we recommend some of the best tourist destinations in Tibet which might suit your travel taste.

The peach blossoms in Nyingchi, Tibet Autonomous Region have been named as “the most beautiful peach flowers in the world”. A great time to visit Nyingchi for the peach blossoms would usually be from March 20 to Apil 15 each year.

The peach blossom valley in Bomi County, Nyingchi, stretches for 30 kilometers, making it one of the longest in China. Peach blossoms can be seen everywhere- around houses, across farmlands and along streams. Peach trees bloom depending on the altitude and climate, so visitors will have the chance to enjoy the blossoms throughout April.

The Yarlung Zangbo River Grand Canyon is the deepest canyon in the world. With a total length of about 500 kilometers, its altitude spans from 1,182 meters at Namchak Barwa, the highest peak of the eastern Himalayas, to 550 meters around the Yarlung Zangbo River Valley in Metog County.

One unique feature of the spring sight here is that visitors can enjoy both the peach blossoms and the snow-capped mountains at the same time.

Nanyigou scenic spot is 20 kilometers away from Milin County and is an important birthplace of the mysterious Tibetan medicine culture. The scenic area rovers a total area of 820 hectares. The ecological conditions here are so good that the place is rich in various animal and plant species.

Surrounded by mountains and shrouded (遮蔽) in clouds, Nanyi Valley is an ideal spring destination for visitors, where you can find peach and azalea blossoms everywhere.

5 . In the middle of the Pacific Ocean lies the tiny island nation of Tuvalu, the fourth smallest country in the world. This group of four islands and five atolls (islands made of coral rock) is famous for its sandy beaches and turquoise (青绿色的) waters and has long been a popular tourist destination for nearby New Zealanders. However, the nation of Tuvalu is at the risk of soon no longer existing, not because of war or political change, but because it will be covered by the rising ocean.

Tuvalu is experiencing the harmful effects of global warming. As the global temperature rises, so does the ocean temperature. Due to the scientific law of “thermal expansion”, when water heats, it gets bigger.     1    . Most experts claim that the effects of climate change will make Tuvalu uninhabitable within the next 50 years. Problems are already emerging. As sea level rises, ocean water containing high levels of salt is travelling further and further inland, destroying the little amount of soil Tuvaluans have to grow crops in.

Even before Tuvaluans began to suffer from the effects of climate change, the life in Tuvalu was tough.     2    . Most of the land on an atoll is rock-hard and arid and the soil that exists on it is usually thin and poor for growing crops. The nation has always had to import food apart from fish.

More serious than Tuvalu’s lack of home-grown food has been its lack of drinking water.     3    . Therefore, Tuvaluans depend almost entirely on rainwater for their water needs. Unfortunately, due to a geographical phenomenon known as La Nina, Tuvalu often suffers from long periods of drought. In the autumn of 2010, after seven months of no rain, the Prime Minister had to declare a state of emergency not only because of a lack of drinking water, but also because the water left was polluted with cholera (霍乱).    4    .

Tuvalu’s problems have led some of its 11,000 inhabitants to consider migrating to Australia or New Zealand.     5    . They know they’ll have to someday, but for as long as possible, they want to remain and make the world aware of what is happening to their homeland due to climate change.
