Answer:
The steel plow and barbed wire
Explanation:
It was in 1837 when John Deere, a blacksmith from Illinois invented a steel mouldboard plough that was strong enough to cut through the stubborn roots of the prairie grasses. This invention turned millions of acres of prairie land into fields for arable crops and grazing ground for huge herds of domesticated cattle. The starving Indians who were displaced resorted to slaughtering the bison in 1872 to 1874 that resulted in the decrease of its population from 7.5M animals to about 750 only.

I would expect that the marine population of iguanas would be larger than the population of the land iguanas. The above text states that both the land and marine iguanas lay their eggs in the sand and that the rats living on the Galapagos Islands eat the eggs buried in the sand. It also states that the food sources are more abundant in the ocean than on the land. So, if we assume that an equal number of land and marine iguana eggs hatch and an equal number make it to their respective food sources, the marine iguana has a greater chance of surviving as its food source is more abundant.
