Scientists are the most interesting people on other. They always want to come up with theories to explain everything. Some of their current research has shown that it is possible to explain how life first emerged on earth over 4 billion years ago. The discovery of the 10 amino acids that existed on earth formed fordable proteins that could provide for metabolic activities of the first organisms. You can read on this theory and you can be sure to find fun in it: How life first emerged on earth. Whether to believe scientists or not is still debatable. But in most cases we do believe them because we have no explanation of our own.
While salt or what is chemically referred to as sodium chloride is important for our health, too much of it is not necessary. Lack of it could cause goiter while too much of it could lead to high blood pressure. People living in ice frozen areas find salt a very important element to de-ice their roads especially during the winter season. While this is a benefit on one side, it becomes a negative impact into their lives on the other hand. This salt is a health hazard since it still gets to man through the food web and food chain processes. This salt is also washed to water bodies which man use thereafter compounding the problems. It is therefore important to be cautious about the water we drink to keep off from diseases. The salt is not only a nuisance to man but also to other living organisms in the environment. For, example, birds presume that these crystals are seeds and therefore proceed feeding on them and eventually they poison their body cells and the effect is death. The chloride also impacts negatively on the aquatic life as well as wildlife which need water for their survival and may also lick this salt from the environment. Too much o these salt in water prevent the oxygen dissolved from reaching the bottom of the water thus cannot support aquatic life. Only those adapted to living in such conditions will survive.
How salt affects vegetation
Vegetation along the roads is very important because it acts as a buffer between the pollutants and water sources. However, this vegetation is not safe from splashes by vehicles and runoff of water to the soil. Most of the shrubs, grass and foliage found along the roads are not tolerant to salt. The nosmotic effects of the salt which includes dehydration and poor uptake of nutrients causes foliage damage as well as the ability of the vegetation to grow. It also destroys the roots. Since we are not in control of the ice on the roads, it is good to plant salt tolerant vegetation along these roads as we look for alternative means of de-icing the roads.
How this salt affects our living environment
The salt from the roads will be carried by the moving air around. This means that our homes are not safe especially the rails around our homes and on our stair systems. If these rails are not tolerant to salty air, then we reap nothing better from the beauty around us because eventually it becomes a site not worth having around you. Salt is capable of eroding non-protected rails. In such a situation, you will need to look for those which have a layer of protection.
Sodium chloride is a necessary evil because despite the impact it has to aquatic, water, human health, vegetation, wildlife, soil, infrastructure and ground water, we still need it for our health as well as other industrial use.
