Question

Which of the following would most likely help to slow down the greenhouse effect?

• A. Ensuring that all excess paper packaging is burned to ashes
• B. Promoting the use of private rather than public transport
• C. Converting tropical forests into grazing land for cattle
• D. Redesigning land fill dumps to allow methane to be collected

Answer 1

The correct option is D Redesigning land fill dumps to allow methane to be collected

• The greenhouse effect can be curtailed by redesigning the landfill dumps so that the methane produced by the decomposition of biodegradable waste is collected effectively and it can be used for the production of biogas as methane is an integral component of it.
• The use of biogas curtails the level of carbon dioxide in the atmosphere and thus reduces global warming and the greenhouse effect.

So, the correct answer is option D.
