Giant pandas are on the verge of extinction because of deforestation and overcapture. Pandas usually live alone, only when it comes to the breeding season will they go out to look for mates, male and female attract each other, pandas will leave their own smell in various places, attracting the arrival of pandas of the opposite sex, in the dense bamboo forest, began to carry out various activities.
Reasons why the giant panda is on the verge of extinctionThe survival rate is low, red pandas.
At birth, it is quite immature, the weight is only one percent of its mother's weight, the newborn cub weighs very little, the average newborn weight is about 145 grams, about one thousandth of the weight of an adult giant panda, the lightest is 51 grams, the heaviest is 225 grams, taking care of the child is a very difficult task for the female giant panda.
The panda with low absorption capacity takes bamboo as the main food, and the giant panda has a low digestion and utilization rate of bamboo, and the food stays in the body for a short time, so it takes a large amount of food and rapid excretion to obtain enough energy to meet its needs, so that the energy intake of the giant panda is greatly limited, and all its activities must take into account the intake of as much energy as possible and consume as little energy as possible.

Among the various disadvantages that pandas are on the verge of extinction, the intrinsic reason for this is the high specialization of feeding habits, reproductive capacity and child-rearing behavior. The external cause is the destruction of the habitat environment, the formation of unconnected islands, leading to population segmentation, inbreeding, and species degradation.
The giant panda has lived on the earth for at least 8 million years, is known as a "living fossil" and "China's national treasure", the image ambassador of the World Wide Society for Nature, and is the flagship species of the world's biodiversity conservation.
According to the third national giant panda population survey, there are less than 1,600 wild giant pandas in the world, which are China's national first-class protected animals.
As of October 2011, there were 333 giant pandas in captivity in China. Giant pandas originally ate meat, and after evolution, 99% of their diet was bamboo, but their teeth and digestive tract remained the same, and they were still classified as carnivores. The lifespan of giant pandas in the wild is 18-20 years, and in captivity they can exceed 30 years.

The important reasons why the giant panda has been downgraded from endangered to vulnerable"Eat"The relationship is close because the giant panda is too picky eater, and its staple food is basically only bamboo, and once the bamboo is destroyed, its survival will be affected.
In addition to this, experts have analyzed four other reasons, which include:
1. Due to the blind activities of human beings, their habitats have been destroyed, resulting in the reduction of their habitat area.
2. The panda's own reproductive ability is reduced, its reproductive system is infected by certain bacteria, the egg-laying rate of females is reduced, and the desire of males to mate is reduced, which is also a major reason for the imminent extinction of pandas.
3. The survival rate of baby pandas is low.
4. Pandas are more dependent on their place of residence and less adaptable to environmental changes.
Giant pandas downgraded from endangered to vulnerable:
According to the first report, on the morning of July 7, the first press office held a press conference, Cui Shuhong, director of the Department of Natural Ecology Conservation of the Ministry of Ecology and Environment, introduced that China has established a relatively complete system of natural protected areas, large areas of natural ecosystems have been systematically and completely protected, and wildlife habitats have been effectively improved.
The survival of rare and endangered species such as wild giant pandas, Tibetan antelopes, and elk has been improved. The populations of some rare and endangered species have gradually recovered, and the number of Siberian tigers, Amur leopards, Asian elephants, crested ibises and other species has increased significantly.
The wild population of giant pandas reaches more than 1,800.
Be. Those that can become national first-class treasure animals are basically endangered.

On the one hand, it is to adapt to the cold environment. Pandas inhabit high altitudes, often have long winters and a lot of snowfall, so it is so cold that white fur alone is not enough. In the process of evolution, in order to protect the visual organs, there is a "dark circle" that everyone loves, and similarly, in order to ensure that the chewing organs, olfactory organs, auditory organs and locomotor organs are not frostbitten, their coat color changes from light to dark, absorbing sunlight, just as people often wear dark clothes in winter, with dark earmuffs, gloves, and knee pads, which plays a role in reducing heat loss. >>>More
