1. Severe light pollution, human beings are disabled, and all things are suffering. In an ancient Indian hymn, www.biquge.info pen & fun & pavilion once described: "The sky is full of strange lights, like the power of the Holy Spirit, and only a thousand suns can compete with it." But the Indian sutra also says, "If a thousand suns shine in the sky, mankind will perish and the earth will suffer." The scene after the atomic bombing of Hiroshima is the most vivid interpretation of this poem. After the nuclear weapon explodes, it emits a strong flash, and then turns into a huge fireball with a huge diameter, hanging high in the air, like a thousand suns appearing in the sky, and in an instant, the vast sky becomes bright and incandescent due to the strong light, and everything on the ground loses its outline, and the blind people see the light in amazement, while thousands of people are blinded for life because of the intense flash.

2. Man-made geological disasters may become a reality. The explosion of a nuclear weapon will cause a constant loud noise that shakes the ground like an earthquake. In the explosion of the world's first atomic bomb, the Alamogordo, the continuous loud noise can be heard within a radius of 160 kilometers, and the glass windows in the city of Sylfer, 290 kilometers away, were shattered, leaving not only a large crater with a radius of 400 meters, but also the sand within 700 meters around the center of the explosion was burned into a glass-like crust, shaped like a white-hot platter. At present, "ground-penetrating nuclear weapons" are the new favorite, which can destroy the enemy's fortified installations, such as reinforced underground bunkers, underground passages and caves used for military purposes. It is reported that the United States is developing a small nuclear bomb that can penetrate 10 to 15 meters into the ground, which can not only destroy enemy caves in lofty mountains and mountains, but also destroy military installations hidden deep underground.

3. The ecological environment will face a catastrophic test. Clean air, water, and sunlight are the three basic elements that support the entire ecosystem, and they are also nature's gift to human beings. The outbreak of nuclear war would bring catastrophic changes to these elements. The huge thermal radiation produced by the explosion of a nuclear weapon will sharply raise the temperature of the air to 30,000 °C, which will not only wipe out all life that may escape within the effective range, but also deplete the moisture in the air and emit a large amount of toxic gases. If the target is a nuclear power plant, a large chemical enterprise, an oil field, a large oil tanker and other facilities, the bombing will cause a large amount of toxic chemicals, oil smoke and carbon oxides to be emitted into the air, seriously polluting the air, soil and water bodies in the adjacent areas; If the target is an important ecological facility such as a hydropower station or a large reservoir, it will cause flooding and cause ecological disaster to the system. A nuclear explosion also sends a large amount of nuclear soot and nuclear dust into the stratosphere, which reflects sunlight for a long time, so that a considerable proportion of sunlight cannot enter the earth's surface, and the average temperature of the ground will also drop significantly on days without sunlight. When the yield of nuclear weapons grows larger and exceeds a certain level, there will be a "nuclear winter".

4. Radiation contamination will be the main culprit affecting public health. When an atomic bomb exploded, nearly 200 radioactive isotopes were produced. Most of those who survived the catastrophe suffered from "radiation sickness". The patient's wound is difficult to heal, and various cancers occur one after another; Babies born after marriage by people who have been exposed to radiation are either congenital malformations or incurable diseases. More importantly, families have been destroyed, wives have been separated, disease and hunger have spread, and the social fabric has been severely damaged, and the mental and physical suffering they have caused to people is like a tragedy that will never be ended.
