Animals living in the wild are particularly vulnerable in natural disasters. Earthquakes, hurricanes, volcanic eruptions, tsunamis, and forest fires can have devastating consequences. Many animals die, drowned or buried alive by dirt, ash, lava, or snow; crushed to death in collapsed or burnt burrows; smashed against trees and rocks, or pelted by hailstones. Others sustain major injuries, including cuts and abrasions to the eyes, wings and gills; respiratory and digestive disorders, eroded teeth; malnutrition; and poisoning from contaminated food and water. Strong volcanic eruptions and fires can temporarily change regional weather, cooling or heating the air, changing winds, or causing rain. Volcanoes, storms, and floods can kill marine animals directly, or cause long-term problems by depositing debris and affecting the temperature and salinity of water. All of this contributes to health problems for marine animals, while changing the circulation of water, which further affects nutrient availability and water temperature

In VN, floods are a natural occurrence. Flood due to rising river water during the rainy season. The amount of rising water that occurs on a river at a level that makes it possible for floods to occur once or many times a year. into low-lying areas and cause widespread inundation over a period of time. Floods are known as large and especially large when they cause great and prolonged damage to people and property. In order to monitor the changes in the water level on the river, people measure the water level and draw it into a water map. bridges, sewers, railways, etc. Not only causing material damage, floods also cause human and animal injuries due to drowning or injury due to flooding.

Humanity is facing the risk of extinction due to the impact of environmental pollution leading to "climate change and recent natural disasters such as earthquakes, tsunamis, volcanoes... measure for humanity”. From the past few years, humanity has had to face the threats of nature, natural disasters and epidemics that endanger human life. Remember in 2005, the tsunami swept away tens of thousands of people in Thailand and Indonesia. In 2008, an earthquake devastated Sichuan (China). More and more "cancer" villages appear in Vietnam and the world... these are alarming numbers, showing the anger of nature at the mistakes of man. The causes leading to the above consequences are due to: Human impact on nature such as deforestation, ecological imbalance, use of chemicals such as pesticides and herbicides, lack of science. Then industrial exhaust fumes, urban exhaust fumes puncture the ozone layer, causing the greenhouse effect and global warming. Humans are constantly building, chiseling the earth, building tunnels, mining to deform the earth's crust. Humans with hatreds, ambitions for world hegemony, non-stop arms races, production of chemical weapons, bombs, and constant wars... All will lead to the anger of nature and newspapers. sign of the doom of the earth. According to the Mayan calendar, 2012 is the apocalyptic year, the prophet Vanga predicted: after 2010 there will be earthquakes, volcanoes and tsunamis... now coming true. Let's join hands to protect the environment with practical actions: Do not burn, destroy, or exploit minerals indiscriminately, causing environmental damage and ecological imbalance. Do not discharge oil, grease, toxic chemicals, radioactive substances beyond the permissible limit, wastes, animal and plant carcasses, bacteria, viruses that are toxic and cause disease into water sources; do not bury or discharge into the soil hazardous substances beyond the allowable limit; States commit not to use and produce chemical weapons, not to wage war; If using nuclear power, there must be a strict process to preserve it to avoid terrible incidents such as the explosion of the nuclear reactor in Japan (2011), the explosion of the Chernobyl nuclear reactor in Russia (1986) causing many injuries to children. people.
