Ecological Impact
The donkeys have a serious impact on the environment they live in. Their presence can cause a wide range of problems: they may spread weeds by carrying seeds in their hair and feces, they may damage vegetation through overeating, they may foul watering holes in the drought season, and they can cause erosion with their hard hooves. These damages, particularly those to the watering holes, have the potential to make native plants and animals locally extinct. The donkeys also have an impact on local agriculture. They sometimes can over eat pasture grasses and destroy fences. They are also known to infect domestic animals with diseases.

Famous quotes containing the words ecological and/or impact:
“The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.”
—Freeman Dyson (b. 1923)
“Too many existing classrooms for young children have this overriding goal: To get the children ready for first grade. This goal is unworthy. It is hurtful. This goal has had the most distorting impact on five-year-olds. It causes kindergartens to be merely the handmaidens of first grade.... Kindergarten teachers cannot look at their own children and plan for their present needs as five-year-olds.”
—James L. Hymes, Jr. (20th century)
