Next to a water source. And the drainage of marshy soils made it possible to create fertile areas for agriculture. Importance of wetlands Wetlands are extremely important for the environment. They can purify water, filter and remove pollutants from the soil, displace flood waters, and provide shelter for animals. They are also capable of capturing and depositing climate-influencing carbon , which combines with oxygen to form the gas (CO 2 ) responsible for the greenhouse effect . Peatlands, for example, store at least twice as much carbon as all the world's forests. How many wetlands have disappeared A study in Nature looks at how many wetlands have been destroyed by humans since the 18th century.
Previously it was believed that up to 50% of these lands could disappear. According to new data, this figure is closer to 21% - in total, this is an area the size of India. Some countries have suffered greater losses than others. For example, Ireland has lost over 90% of its wetlands. reason was their Russia WhatsApp Number List drainage for agriculture. insignificant on a global scale. However, this can seriously affect neighboring settlements, which begin to flood in spring and autumn. The process is also catastrophic for the local flora and fauna. Approximately 40% of the Earth's animal and plant species live and breed in wetlands.
In addition about a billion people depend on wetlands for food, raw materials, nutrients, and hydropower. Scientific work inspires hope In the study, scientists described the complexities that hinder the protection of wetlands. For example, sometimes experts cannot determine whether an area falls into this category. This is due to the fact that the amount of humidity in some regions in a particular season is difficult to measure. The researchers also note that the disappearance of territories occurs unevenly. (taxa) bas on common characteristics. The scientist describ the results of his work in the Elementary Theory of Botany.
