There are many reasons for natural disasters. Human activities play an important role in the frequency and severity of disasters. Natural disasters are to impair the balance of the environment. Human factors increase the cost of property damage and loss of life. Understanding the causes of natural disasters can provide clues to their prevention
According to the US Environmental Protection Agency (EPA), fire is forbidden and floods are the most common natural disaster affecting Americans. Floods are a factor of 90% of natural disasters. Floods cause both nature and humans. Storms can cause flooding that exceeds the capacity of the environment and artificial structures. The dam and dam brought about erroneous reassurance that was revealed in the 1993 flood in the upper Mississippi River Basin. I learned a painful lesson. Destruction of wetlands eliminates natural means of absorbing floods
Fire is a natural environmental manager. They will create and maintain ecosystems such as grasslands and pine forests. In fact, the grassland evolved with the presence of fire. Ecosystem health depends on this disturbance. The fire removes garbage from the surface of the soil and releases nutrients to the environment. It also produces favorable conditions for seed germination. If you suppress the fire, garbage collects and a catastrophic fire may occur. Plants and trees adapt to the existence of fire. However, higher temperature crowns may kill plants altogether. These fires are more difficult to control. According to the US Forest Department, the cost of suppressing fire is high, reaching 1 billion dollars a year.
Drought has a greater impact than any other natural disaster. The drought of the year caused more than US $ 6 billion in damage to the United States. It is safe to say that drought has a greater impact in modern times. More people are affected by land and food crop losses and environmental damage. Minor problems obscure direct impact. Compressed and dried soil is susceptible to topsoil loss and erosion. In the dry state the fire will become more common. There is evidence that global warming may cause increased drought frequency and global climate change
Like the drought, the National Climate Data Center has recorded an increase in harsh weather events in the last 100 years. Notification system is in place, but there are loopholes in property damage and loss of crops. Development also complicated the impact of these events. Increased development has resulted in a reduction in wetlands and an increase in impermeable aspects such as roads and driveways. This will create a flood and flood scenario. Like drought, scientists believe there is a connection between global warming and climate change.
Not all natural disasters can be prevented. All natural disasters have their own and complicated factors. Understanding the fundamentals of ecology can provide the key to mitigate its impact. Natural evolution involves natural disasters and confusion. The best precaution is to study strategies found in nature.
Floods are the most common natural disaster, the leading cause of death from natural disasters worldwide. Due to deforestation and coastal areas, river basin, population near lakeside, the risk of catastrophic losses due to floods is high. The purpose of this review is to explain the impact of flood events on population mortality, injury and evacuation and to identify as much as possible the risk factors associated with these results. This is one of five comments on the impact of natural disasters on humans.
