FAQs on Mangroves : Guardians of the Coast Video Lecture - Class 9
| 1. What are mangroves and why are they called "Guardians of the Coast"? |  |
Ans. Mangroves are salt-tolerant trees or shrubs that grow in coastal areas, brackish water, and estuarine environments. They are called "Guardians of the Coast" because they play a crucial role in protecting the coastline from erosion, storms, and tsunamis. Their dense root systems act as natural barriers, reducing the impact of waves and stabilizing the soil.
| 2. How do mangroves contribute to the biodiversity of coastal areas? | |
Ans. Mangroves contribute to the biodiversity of coastal areas by providing habitat and food for a wide range of species. Their complex root systems create a diverse and dynamic ecosystem, providing shelter, nesting sites, and feeding grounds for numerous fish, crustaceans, birds, and mammals. Many species, including endangered ones, rely on mangroves for their survival.
| 3. Can mangroves help mitigate the effects of climate change? | |
Ans. Yes, mangroves can help mitigate the effects of climate change. They are highly efficient in sequestering and storing carbon dioxide, one of the main greenhouse gases responsible for global warming. Mangroves have the ability to absorb and store significant amounts of carbon in their biomass and sediments, thus reducing the concentration of CO2 in the atmosphere.
| 4. How are mangroves affected by human activities? | |
Ans. Mangroves are often negatively impacted by human activities. Deforestation, urban expansion, pollution, and aquaculture development are some of the major threats to mangrove ecosystems. These activities lead to the destruction of mangrove habitats, loss of biodiversity, and disruption of the delicate balance of coastal ecosystems. It is crucial to implement sustainable practices and conservation measures to protect mangroves.
| 5. What are the economic benefits of mangroves to local communities? | |
Ans. Mangroves provide numerous economic benefits to local communities. They serve as a source of livelihood for many through fishing, tourism, and traditional practices like honey collection and wood harvesting. Mangroves also act as natural barriers, reducing the impact of storms and protecting coastal infrastructure. Additionally, they support commercial activities such as aquaculture and provide opportunities for ecotourism, contributing to the local economy.
