Floods are thought of as natural disasters for most people. Floods have been known to wipe out entire towns and neighbourhoods, decimating homes, destroying businesses and causing death to humans and animals.Additionally, the floodwater itself can harm the environment by carrying off any toxins, gasoline or poisonous chemicals to lakes and rivers where even more damage can be done to people, animals, and plants. One of the most hazardous effects of floods to cities and urban areas, is that flood water also carries off sewage. This can lead to causing serious diseases for people and animals.Over time, the flooding which has been known to occur in the Mississippi Delta actually helped create the complex systems that allow living beings to thrive in this region. The land is sinking so without added sediment from the river when it floods it would fall well below sea level. In this instance, the environmental effects of floods are positive. While the environmental effects of floods can be both positive and negative regarding the environment and those of us who share living in it, there is the potential for minimizing negative effects. These effects can be halted through flood prevention programs by making use of environmental reports.These are often up to municipalities and cities to devise themselves. After all, different regions get different types of flooding or they have lesser or higher risks of flooding. One aspect of flood prevention in any area, even one not prone to flooding, should be minimizing the use or storage of hazardous chemicals or toxic substances.Any area can be a flood zone, and almost any flood insurer will attest to this. However, with good preparation, damage and injuries can be minimized. Environmentally speaking, floods are mostly a part of the cycle of life. Most floods have beneficial effects more than they have damaging effects.
