Read the following text and make a flow-chart showing the factors causing the disappearance of the mangrove forest. (One is done for you)-

  A vast mangrove forest shared by Bangladesh and India that is home to possibly 500 Bengal tigers is being rapidly destroyed by erosion, rising sea levels and storm surges, according to a major study by researchers at the Zoological Society of London (ZSL) and others. Natalie Pettorelli, one of the report's authors, said, "Coastline retreat is evident everywhere. A continuing rate of retreat would see these parts of the mangrove disappear within 50 years. On the Indian side of the Sundarbans, the island which, extends most into the Bay of Bengal has receded by an average of 150 metres a year, with a maximum of just over 200 metres; this would see the disappearance of the island in about 20 years." The Sundarbans is known for vanishing islands but the scientists said the current retreat of the mangrove forests on the southern coastline is not normal. "The causes for increasing coastline retreat, other than anthropogenic ones, include increased frequency of storm surges and other extreme natural events, rises in sea-level, and increased salinity which increases the vulnerability of mangroves," said Pettorelli.

These lines are from the poem "Dreams" by Langston Hughes.

Langston Hughes was a prominent African American poet, social activist, novelist, playwright, and columnist, known for his insightful portrayals of black life in America from the twenties through the sixties.

In the line "Life is a broken-winged bird that cannot fly," Hughes uses a powerful metaphor to emphasize the importance of dreams. He suggests that without dreams, life loses its vitality and potential, much like a bird with broken wings that is incapable of flying and thus fulfilling its natural purpose. Dreams give life direction and hope; without them, life becomes stunted and devoid of possibility.

Culture plays a significant role in shaping the identities and behaviors of adolescents. It influences their values, beliefs, and norms, which in turn affect how they perceive themselves and interact with the world. Through cultural practices and traditions, adolescents learn what is expected of them within their community. Media and technology also contribute to cultural influences, exposing adolescents to a variety of perspectives and lifestyles. Peer groups, heavily influenced by cultural context, play a crucial role in social development and the formation of social norms. Overall, culture provides a framework within which adolescents navigate their formative years, impacting their choices, aspirations, and sense of belonging.

Biodiversity is crucial for maintaining the balance of ecosystems that provide essential services to human life. It ensures the availability of a wide range of resources such as food, clean water, and medicines. Diverse ecosystems are more resilient to environmental changes and disasters, protecting against the impacts of climate change. Biodiversity also supports agricultural productivity by maintaining healthy soil and pollinating crops. Economically, it contributes to industries like tourism, agriculture, and pharmaceuticals. Ultimately, the health of our planet and the sustainability of human livelihoods are deeply interconnected with the preservation of biodiversity.
