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.
The cuticle decreases water loss and stomata assist gas exchange. The plants from wet habitats must have a comparatively large number of stomata and thin cuticle. The plants existing in dry habitats must have comparatively few stomata and thick cuticle.

Explanation:
Hydraulic facturing, aka fracking, uses toxic chemicals above some regulations which may lead to a leak into water supplies and therefore contaminate it.
It has not much to do with coal, more to do with oil and natural gases
Because of fracking now making it accessible to reach sources in vast number that were previously unacessible, it leads to decreases in gas prices
Hope this helps :)
