Question

Erosion of America's farmland by
wind and water has been a problem
since settlers first put the prairies and
grasslands under the plow in the
nineteenth century. By the 1930s, more
than 282 million acres of farmland
were damaged by erosion. After 40
years of conservation efforts, soil
erosion has accelerated due to new
demands placed on the land by heavy
crop production. In the years ahead,
soil erosion and the pollution
problems it causes are likely to
replace petroleum scarcity as the
nation's most critical natural resource
problem.

passage that erosion in America
1. Has 382 million acres ever since settlers first put the
prairies and grasslands under the plow 2. Has been
so slow and is not harmful in the future 3. Occurs
only in areas with no vegetation 4. Can become a
more serious problem in the future​
