Answer:
Soil erosion causes siltation in rivers, dams, etc. In some areas, huge river deltas are formed (such as River Nile delta) because of soil erosion. Such places are good for agriculture but not good for urbanization. However, some people do not care about it, they just want to construct buildings on alluvium type soils.
This should be Speciation.

Logging leads to higher erosion. This leads to increased sediment transport in rivers. The majority of rivers run to the ocean. Higher sediment loads in the ocean could block out sunlight and disrupt filtering mechanisms of coral reef organisms.
True. laws are there because government doesn’t want something to happen, trying to predict what’ll solve it. :)
