Answer :
Final answer:
Farmers' drastic alterations of the breeding zones for Rocky Mountain locusts led to ecological disruption and a decline in this species. The conversion of land for agriculture disrupted their natural habitat, making it unsuitable for breeding. This illustrates how agricultural practices can profoundly impact local ecosystems.
Explanation:
Impact of Agricultural Practices on Rocky Mountain Locust Breeding Zones
The question asks about the consequences of farmers "drastically altering" the breeding zones of the Rocky Mountain locusts. When farmers plowed and irrigated the land, they significantly changed the natural habitat of these locusts.
As farming practices involved turning the soil and planting crops, the ecological balance of the region was disrupted. The plowing broke up the stable soil profile and destroyed the natural grasses, which provided both habitat and food for the locusts. By introducing crops with shallower root systems, farmers made the soil more prone to erosion and unsuitable for the locusts' breeding needs.
Consequently, the locusts could no longer find their required breeding grounds. This led not only to a decline in their populations but also to the potential extinction of certain local populations of the locusts, as they could be easily scared away or unable to thrive in the altered landscape.
Examples of Ecological Disruption
This phenomenon reflects a broader pattern where human activities can lead to unforeseen consequences in local ecosystems. For instance, the introduction of non-native species can create imbalances and further impair the survival of native species, just as was seen in other examples like the Dust Bowl in the 1930s or the case with invasive beetles in new environments.
