Re-order Paragraphs
Arrange the sentences into the correct order.
Put the sentences in the correct order:
- City planners now treat wetlands as essential infrastructure, valuing them as highly as any pipe or drain in a modern flood-control system.
- Within a few years of restoration, the returning marshland began filtering pollutants from runoff while also sheltering birds and fish that had disappeared from the area.
- Recognizing the mistake, several municipalities started restoring wetlands at the edges of rivers and floodplains, replanting reeds and native grasses that had been cleared away.
- Decades later, those same cities began flooding more often, and researchers traced the worsening damage back to the loss of wetlands that had once absorbed excess rainwater.
- As cities expanded outward in the twentieth century, engineers routinely drained marshes and wetlands, viewing them as wasted land better used for roads and housing.
