An Analysis of the Boston Sewer System
At the turn of the century, Boston had one of the most advanced sewer systems in the country. Through decades of neglect and a failure to truly update the system until the 1980's, the pollution in Boston Harbor became so bad that the harbor became a national embarrassment.

The Importance of the National Pollution Discharge Elimination System
The National Pollution Discharge Elimination System (NPDES) was created in order to help regulate and monitor point sources of pollution into surface waters. As part of the Clean Water Act of 1972 Section 402, the NPDES was created as a permit program for any type of facility that has a point source of water discharge (EPA, 2014). According to federal law, a basic definition of a point source can be anything such as: a pipe, tunnel, ditch, manhole, or a…...

One Of the Largest Aquatic Mammals On Earth
Whales are regarded as one of the largest aquatic mammals on Earth. However, at one point in their evolutionary history, they were land-based animals. Modern-day cetaceans evolved 55 million years ago from terrestrial animals that resided near brackish estuaries. In order for this shift to occur, whales had to change every part of their anatomy. Additionally, the decline of whales has likely negatively altered the structure and function of the ocean, suggesting that whales play a prominent role in the…...

Factors That Affect The Distribution Of Biomes
These factors include plate tectonics, atmospheric circulation, and tropical convergence zones, to name a few. The movement of the Earth’s plates causes continental distribution, mountain formation, and oceanic breaks. Different biomes are found because of the different latitudes/longitudes, altitudes, and depths respectively. Temperature and moisture at higher elevations differ from that of lower elevations thus creating different distributions for biomes to be found. Atmospheric circulation patterns cause wind patterns that will warm/cool different areas. Around the equator, where the sun…...
