Two isotopes of hydrogen, tritium and protium, undergo nuclear fusion in the sun to give helium, neutrons and a tremendous amount of energy. This reaction occurs at the very high temperature found in the sun and yields tremendous amount of energy.

The potato crop devastation occurred in Ireland for not using one single potato species.
Explanation:
Potato became the staple crop of 18th Century Ireland and was easy to grow in the soil of this place. Later, it became the most dependent crop of the people of Ireland which made its supply very demanding leading to the yielding of more than one species of potatoes.
This yielding reduced the variety in the genetics of potatoes that helped in preventing the disease that affect potatoes by making the Irish people susceptible to famine. The Phytopthora bacteria affected the potatoes of North America in the year 1840 and Ireland’s moist weather in that same year made the blight to thrive.
