There is a problem that the delicate desert ecosystem is destroyed by the construction of walls at the border between the United States and Mexico. Many living things, including the endangered Mexican wolves and the Sonora desert Jaguar, can not move as before, and shortages of food and partners can occur. According to a report published by the US Fish and Wildlife Service in 2016, the walls are constructed, making it possible for 111 endangered species, 108 migratory birds, 4 safe areas and fish egg hatchery, and countless wetlands It is said that it is considered to be influential.

There are places in the state of Texas such as the Rio Grand Valley where various organisms inhabit. There are 700 species of vertebrate species that live only in the Rio Grand Valley, and revenues from wildlife observers, such as bird watchers, are about $ 463 million annually (about 53 billion yen) . It is possible to observe these creatures because they can move freely between the borders, but the wall built by President Trump will break the Rio Grand Valley.

In the past, in 2005 when President George Bush was in office, a fence of barbed wire ranging from California to Texas at a height of 18 feet (about 5.5 meters) - a distance of 650 miles (about 1050 kilometers) Although it was installed, the number of 16 kinds of living things decreased by 75% by 2011 due to this influence.

"At this moment transportation existing in the border has already affected all living organisms," said biologist Louise Misztal. "Various creatures such as Puma, Bear, Jaguar, Ocelot and so on need to move through the mountains in order to get water and food," and the living things habitat habitat due to the change in the global environment that will occur from now Given that it is a transfer, the walls of the border are also expected to interfere with environmental adaptation of such living beings.

Also, although birds may fly in the sky, they may not be affected by the walls, but the birds move the star in the night sky instead of a map so if the walls are illuminated with a light it hinders the movement I will. In addition, Misztal said, "Besides the influence on wild animals we can anticipate at this stage, there may be long-term effects that we can not see yet at the moment," he said.
