Wetlands are often drained in many regions to facilitate human use of the land. This happens a lot within the Pairie Provinces of Canada, where wetlands are drained to make way for agriculture. Wetlands are also often drained so as to use the land for building houses. Humans have also altered the flow of rivers through constructing dams and over-abstracting water. In many regions, depressions that would have been flooded in the past to form wetlands are no longer saturated. Wetlands also act as a 'sink' for many pollutants, and much of the pollution released into upstream rivers by humans may settle into the relatively stagnant waters of wetlands, to be absorbed into the sediments, where often it acts as a chronic pollutant, negatively effecting the aquatic ecosystem and water quality downstream.

The arctic fox is an incredibly hardy animal that can survive frigid Arctic temperatures as low as –58°F in the treeless lands where it makes its home. It has furry soles, short ears, and a short muzzle—all-important adaptations to the chilly clime. Arctic foxes live in burrows, and in a blizzard they may tunnel into the snow to create shelter.
Answer:
What is a monomer?
A monomer is a molecule that can react together with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.
What is a polymer?
Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester.The term polymer is often used to describe plastics, which are synthetic polymers.
