There can be no greater example of a mankind's creative genius than for him to create new abodes of life throughout the solar system. Today, with an increasing population of more than six billion people and the fear of possible disaster, the need for an alternate home for mankind has become urgent. Mars is the only planet in our solar system, besides Earth – that has all the ingredients necessary to support life. Though the average surface temperature on Mars is frigid and it is a desolate lifeless planet, Mars once had an atmosphere thick and warm enough to allow for the flow of liquid on its surface.

If it is ever done, transforming a dry, desert-like Mars into a lush environment that can support the flora and fauna of the Earth, will be a mammoth task requiring decades or maybe centuries! Two methods have been proposed to make this a reality. One is placing large orbital mirrors that will reflect sunlight and heat onto the polar caps of Mars, which would melt the ice there. Gradually, the rise in temperature would release the greenhouse gases and heat the planet.

Another option would be to set-up solar-powered, greenhouse gas producing factories. Imitating the process of photosynthesis, the atmosphere of Mars would be oxygenated to the extent that people would survive on Mars with only a breathing apparatus.

While we may reach Mars this century, it would take several millennia for transforming it into a planet wherein plants and animals can flourish.

Select the most approproiate option to complete the following sentence:

In the light of ever increasing population, scientists view Mars planet as a challenge to ____________________________.

Solution

✅ Correct Option: 2

The passage links the rising population and fear of disaster to the urgent need for an alternate home, and then discusses methods to transform Mars into an environment supporting life. So, in light of the growing population, Mars is viewed as a challenge to make it habitable, not merely a display of ingenuity or supremacy.
