Question

Bio-fuels have become controversial because

• A. they increase environmental pollution
• B. they slow down industrialization
• C. they reduce food cultivation
• D. they lead to degeneration of soil

Answer 1

The Correct Option is A

Bio-fuels have become controversial primarily because they increase environmental pollution. While biofuels are often marketed as an eco-friendly alternative to fossil fuels, their production and use can sometimes result in environmental harm.

For instance, the large-scale production of biofuels, particularly from crops like corn and sugarcane, can lead to significant land use changes, deforestation, and increased pesticide and fertilizer usage. These factors contribute to soil degradation, loss of biodiversity, and pollution of water sources. Additionally, biofuels may emit harmful gases during production and combustion, undermining their environmental benefits.

The correct answer is: They increase environmental pollution, as the production of biofuels can lead to pollution and environmental damage in various ways, despite their renewable nature.
