Geography ch 5 - Natural Vegetation and Wildlife — Social Studies STD 10 — Question

Introduction: Both Brazil and India are fast-developing nations. Due to rapid urbanization, industrialization, and increasing population, both countries face several severe environmental challenges.
Key Environmental Issues:
1. Deforestation:
In Brazil: Large patches of the Amazon rainforest are being cleared for cattle ranching, commercial farming (like soybean), and timber.
In India: Forests are being cut down to accommodate the growing population, for mining activities, and to build infrastructure like dams and highways.
2. Pollution:
Water Pollution: Industrial waste and untreated sewage are dumped into rivers. For example, the Ganga and Yamuna in India and the coastal waters near major cities in Brazil suffer from high toxicity.
Air Pollution: In mega-cities like Delhi (India) and São Paulo (Brazil), smoke from factories and vehicle emissions have led to poor air quality and respiratory issues.
3. Loss of Biodiversity:
Because of the destruction of natural habitats (forests), many unique species are losing their homes. Illegal poaching and wildlife smuggling remain major threats in the biodiversity-rich regions of both the Western Ghats (India) and the Amazon basin (Brazil).
4. Shifting Cultivation (Slash and Burn):
The practice of clearing forest land by burning it for agriculture (known as 'Roca' in Brazil and 'Jhum' in India) causes massive air pollution and reduces soil fertility over time.
5. Urban Congestion and Waste Management:
Rapid urbanization has led to the growth of slums (like Favelas in Brazil and Dharavi in India). Lack of proper waste disposal systems leads to land degradation and the spread of diseases.
