Abstract

Context:

The City of Flint was already distressed because of decades of financial decline when an estimated 140 000 individuals were exposed to lead and other contaminants in drinking water. In April 2014, Flint’s drinking water source was changed from Great Lakes’ Lake Huron (which was provided by the Detroit Water and Sewerage Department) to the Flint River without necessary corrosion control treatment to prevent lead release from pipes and plumbing. Lead exposure can damage children’s brains and nervous systems, lead to slow growth and development, and result in learning, behavior, hearing, and speech problems. After the involvement of concerned residents and independent researchers, Flint was re-connected to the Detroit water system on October 16, 2015. A federal emergency was declared in January 2016.

Sample PEE essay. Beautifully written by my Grade 7 student

 “Can Money Buy Happiness?”

Written by: Kate Lee


Is it possible for money to make someone physically and emotionally happy?

Happiness is a tough concept to define. Although some people believe that money can provide happiness, others disagree. Wealth can provide entertainment, but the best things in life are sometimes free.


Even if you had all the money in the world in the palm of your hands, loneliness,

depression, stress, and sadness can still occur. Consider Robin Williams, a well-known American actor and comedian. He has amassed a massive fortune and has been noticed for his improvisational skills in a variety of movies and shows. On August 11, 2014, Robin Williams committed suicide due to depression and anxiety issues. Such outbursts are very understandable. Pop artists and comedians alike face a barrage of hatred, misunderstanding, and criticism since they are public figures. This case exemplifies how wealth alone cannot heal a broken soul.


Family and friends have been there for us throughout our whole lives. They've led

us down a delightful path. With them, we have created all of our memories. All the scars, laughter, embarrassments, and joys we’ve shared are irreplaceable. Recollection is something that no amount of money can buy. A great deal of income can buy a fantastic experience, whether it's swimming with dolphins off the coast of Western Australia or bungee jumping over a glass bridge. What's important is who you spend that special time with, regardless of what you do or where you go.


In conclusion, happiness and sincerity are two human qualities that are completely free. Helping others, keeping calm, and caring about others boost your happiness. This type of joy cannot be purchased with money. True happiness is priceless.
