Where could they possibly plant a hybrid tree such as the one they are about to graft? Jace spaced out as soon as he tried to look for a possible, and logical answer. He did hear what Mel had to say...but thought it impossible for them to travel to Mars. Sure, they are magical and all, but then...travelling to another planet via magical means is still quite...a farfetched idea, isn’t it? Not impossible though, but just like muggle inventions and developments, it would take the wizarding experts to come up with such...innovation.

Jace blinked, and tapped the tip of his quill against his not quite empty parchment. “Fumō.” He muttered the Japanese word for deserted under his breath, and grinned at the professor. He raised his hand to offer his answer. “As an element, Nitrogen can be transformed into a mineral, which, I suppose will make the soil rich. Over time, it can revitalise the rest of the land, making it fertile so people can use it to plant more trees, and maybe crops." Muggle science, really. "The anti-pollutant tree will obviously clean the air, so I was thinking...maybe we can plant the trees somewhere that is barren? A wasteland perhaps?”Jace said putting his hand down, eager to know what the professor has in store for them, besides grafting.
