"Oh, there will be a lot of people!"

Tang Xiaoxin looked at the panda in front of the fence and suddenly felt a little muggy.

Blankly turned his head and was startled. Unconsciously, he was surrounded by people.

Originally, there were few people on the upper platform, but with the passage of time, the number of tourists to the panda Pavilion gradually increased, and many tourists came up.

"Let's go somewhere else!" Mother Tang suggested.

There will be so many people, and the panda began to eat bamboo and didn't play.

Father Tang is still a little reluctant to give up. He feels that the panda hall is overlooking on the upper floor. The more he looks, the more interesting it becomes.

Especially at the boundary in the middle, we can see two pandas living on one side, one eating bamboo and the other playing. Each panda is very happy. There is a wonderful sense of harmony among the moving pandas, the static venues and the flowing tourists outside.

He expressed his own opinion: "pandas need their own territory space. Look at this two pandas, one female and one male, living on both sides of the exhibition hall, do not interfere with each other. We tourists are outside, they are inside, and we keep a distance from pandas. Instead, we are more harmonious, aren't we?"

Tang Xiaoxin said in surprise, "Dad, you are still a philosopher! You can see so much from a pavilion. "

She didn't think so much, but it makes sense to listen to her father!

Back to the lower floor, he thought, "you can go around and see other animals first. I want to see the exhibition boards here!"

Tang Ma glanced at the nearby Panda Restaurant and said, "OK, let's come over at 10 o'clock later and have dinner in the Panda Restaurant!"

"Eat so early? It's too early. I'm not hungry yet. "

Tang's parents agreed: "if you want to eat here, you should take advantage of the early. There must be no seats late. There are so many people today."

Tang Xiaoxin strolled in front of the popular science exhibition board and saw a lovely picture of a panda lying on a tree on a conspicuous exhibition board with the title: "beauty is justice!"

"People always flock to beautiful things. Animals with high beauty are called 'flagship species' in conservation biology.

With its charming appearance, pandas are loved by the public and become stars in the animal world. There are polar bears, elephants, finless porpoises, golden monkeys, tigers, snow leopards and so on. They are flagship animals.

Compared with complex ecological concepts, flagship species have more appeal and can attract public attention, attract public support and even join conservation actions.

Scientists have found that the donations raised by high-value animals in a zoo can be 46 times higher than those raised by low-value animals! "

Tang Xiaoxin did not make complaints about it: "Wow, it's a real face looking world. It's too realistic."

"Concepts corresponding to flagship species, as well as cornerstone species and umbrella species, indicating species.

Cornerstone species, also known as key species, is a key role in the ecosystem, such as the pika on the Qinghai Tibet Plateau!

In the past two or three decades, pikas have been regarded as pests, which has promoted the desertification of the land. After large-scale poisoning, a large number of pikas have died, and many Raptors that prey on pikas have died because they eat poisonous individuals.

Later, it was found that after the pika turned over the soil and dug holes, the water permeability of the soil would be greatly improved, and the surface runoff would be reduced, which could reduce the probability of soil erosion and flood, and make the grassland ecosystem more healthy. In fact, it is grassland degradation caused by human overgrazing.

The role of umbrella species is to protect and shelter other species.

A species can play different roles at the same time. For example, the giant panda is both a flagship species and an umbrella species.

96% of the giant panda habitats coincide with the distribution hotspots of endemic species in China. The giant panda is like an umbrella. While people protect the giant panda, animals in other habitats are also protected.

Indicator species can reflect changes in the environment and the composition of ecological communities... "

Tang Xiaoxin suddenly said, "so it is!"

She also had some doubts about the usefulness of protecting giant pandas. Now she finally understands.

Animals such as pikas, wolves and wild boars, although they play a very important role in the ecosystem, their appearance is not high. Ordinary people just don't like them and even treat them as pests.

Giant pandas and green peacocks can attract people's attention, make it easier to publicize protection work and increase people's awareness of environmental protection. It can also be used as an umbrella to protect other animals.

Although the title of the exhibition board says "beauty is justice", it is actually telling tourists not to just look at beauty and decide whether they like or dislike animals.

Tang Xiaoxin felt a little touched, pondered for a moment and strolled again.

……

Ten o'clock!

Tang Xiaoxin and her parents got together again and came to the Panda Restaurant.

Sure enough, as Tang Ma guessed, there are already many tourists eating at this time. I'm afraid I won't have a place later.

As soon as I came in, I smelled a faint aroma, lingering on my nose.

"How fragrant!"

Tang Xiaoxin felt very strange. She had eaten a cage of steamed stuffed buns and drank a cup of soybean milk before leaving in the morning. She was not hungry at all, but she couldn't help salivating when she smelled the aroma and suddenly had an appetite.

He chose a seat and sat down. Tang dad directly scanned the QR code on the table and couldn't wait to order.

Mother Tang straightened up, looked left and right, and quietly looked at other people's tables: "what dish is so delicious?"

There is also a table with children next to it!

On the table are a plate of potato balls, a plate of shredded potatoes, a plate of stewed chicken with potatoes, and a plate of bamboo shoots

Mother Tang suddenly found something wrong and wondered, "Why are there so many potatoes? Where can I order like this? "

But look at other people's children and adults. They all eat like thieves and show a very intoxicated expression. The other table is also potatoes!

"Lying C..."

Father Tang opened the order interface and suddenly gave a low cry of surprise.

Mother Tang turned and leaned over: "what's the matter?"

But then she was surprised!

The panda restaurant is positioned at the upper middle level. The family orders several meals and eats three or four hundred yuan.

It's not as affordable as the animal restaurant. A single set meal costs about 40, and it's not as expensive as the lion restaurant. If you want to eat better, order a few beefsteaks and barbecues, and the consumption is easy for thousands.

However, because of the potatoes sent by fangye, the price of the dishes has changed

Stewed chicken with potatoes: 78

Stewed chicken with potatoes Deluxe Edition: 188

Potato balls Deluxe Version: 288

"Waiter, waiter!"

The waiter of the restaurant came over and said with a smile, "Hello, what can I do for you?"

Dad Fang pointed to the potato stewed chicken on the menu and wondered, "Hey, what's the difference between the deluxe version and the ordinary version? Why is it so expensive?"

The waiter respectfully said, "because the potato is an organic potato planted by our principal! It tastes wonderful, healthy, natural and pollution-free. "

Father Fang showed a surprised and tangled expression: "the potatoes planted by your gardener?"

It's understandable that organic potatoes are a little expensive, but why are they so expensive! Just because the gardener planted it? It is also described as wonderful.

Then he ordered some potato balls: "then why do potato balls sell more expensive than stewed chicken!"

The waiter said honestly, "because of potato balls, potatoes use more materials!"
