In the 1800s, the irish wolved the problem of feeding a growing population by planting specifically, they a r e

potato, one in eight irish people died of starvation in three years during the irish potato famine of the 18405
the basis for the devastation of the potato crop was

sexual reproduction and genetic sameness
1)
not for using on just one species of potato
choosing a staple crop that was susceptible to light
d)
planting a crop that did not tolerate the maritime climate

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.
