Class 11 English: Unseen Passage Reading Comprehension

1. Q1. Read the following passage carefully. The Amazon rainforest, often referred to as the 'lungs of the Earth,' is the largest rainforest in the world. It covers an enormous area of roughly 5.5 million square kilometers, spanning nine countries, with the majority located in Brazil. This ecologically rich biome is home to an estimated 10% of the world's known species, including countless insects, birds, mammals, and plant life. Its dense canopy plays a crucial role in regulating global climate patterns, absorbing vast amounts of carbon dioxide and releasing oxygen. Deforestation, primarily due to agricultural expansion, logging, and mining, poses a severe threat to the Amazon's biodiversity and its vital role in climate regulation. Indigenous communities, who have lived in harmony with the forest for centuries, are also deeply affected by these destructive activities. Efforts to conserve the Amazon include establishing protected areas, promoting sustainable practices, and supporting indigenous land rights. The future of this invaluable natural resource depends on concerted international action and a shift towards more environmentally responsible human activities.
