Present an argument in favor of bioengineering.

Bio-Engineering is the use of living vegetation, either alone or in conjunction with civil engineering structures and non-living plant material, to reduce shallow-seated instability and erosion.

Explanation:

DEVELOPMENT OF BIO-ENGINEERING:

In Germany and  Austria wishes to use the low-cost local materials and traditional constructions due to their Financial restrictions of pre-war years 1930's

ADVANTAGES OF BIO-ENGINEERING:

Re-establishing vegetation and store the hydrology from the surface to control of accelerated erosion.

Cost-effective treatments:

EXAMPLE:

GRASS PLANTING

Usually planting the large grass clumps in lines across the slope.

Horizontal lines are used to increase the protection against erosion.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
