Benefits of Eutrophication
Eutrophication entails accelerated plant growth due to increased concentration of nutrients and atmospheric carbon dioxide. On the other hand, nutrient pollution from water runoff can trigger eutrophication processes that pose environmental hazard. Listed below are the positive impacts of eutrophication to the environment.
1. Improves biodiversity
Eutrophication and biodiversity often go hand in hand. Biodiversity not only entails the large animals and plants, but also algae, fungi, bacteria, and various types of tiny invertebrates and insects. These smaller micro-organisms are responsible for enriching the soil with nutrients needed for plant growth. Fungi and bacteria degrade organic matter, which then breaks down into fertile soil.
2. Aids in waste removal
Biodiversity also plays an essential role in decomposing toxic wastes. By eutrophication, organic materials such as twigs, insects, dead animals, logs and leaves are decomposed. This is a delicate process that maintains balance in the ecosystem, whereas certain microbes and insects perform an essential role in removing toxins from the environment.
3. Boosts ecotourism
Since eutrophication leads to the rise of tall forests and woodlands, tour companies promote ecotourism in locations such as jungles and forests, where tourists enjoy hikes and cruises. Revenue from ecotourism can then be used to help prevent the extinction of plants and animals.
4. Source of medicine
Plants and other natural ingredients are incorporated in modern medicine to treat an array of diseases. For instance, cinchona tree native to South America is used to quell the symptoms of malaria, whereas cortisone derived from yams is used as a sedative.
5. Better water quality
The eutrophication process also helps to keep water sources clean and pure. Plants that grow in wetlands help to filter out impurities in water. Additionally, woodlands and tall forest attract rainfall, which in turns leads to increased plant growth.
Eutrophication may pose a negative impact in lakes as it promotes the growth of toxic aquatic plants, as well as overgrown shores.
