Happy Earth Day! - Save Energy, Save Money
By Shahir Masri - 4/22/15

Happy Earth Day everyone! This day was inaugurated 45 years ago today, just at the height of what would come to be the environmental revolution. So how far have we come since the 1960s and 70s? The answer. Far! Reductions in outdoor air pollutants such as sulfur dioxide, particulate matter, ozone, and lead represent some of the greatest advances. Those who lived in populated cities such as Los Angeles 30 years ago can attest to the improvements in visibility alone.

How much paper does a tree produce?
By Shahir Masri - 7/24/14
Answering this question is not easy because the answer depends on a number of variables, such as the density of the wood, the size of the tree, and the type of pulping process used. Recently, however, the Sierra Club published a response to such an inquiry, estimating that a single 8 inch diameter tree produces about 10,000 – 20,000 sheets of paper. Other numbers I’ve seen range as high as 100,000 sheets per tree. This may not sound like many trees necessary to meet consumption, but when you consider that the U.S. alone produced nearly 21 million tons of paper last year, this amounts to millions upon millions of trees.

Conserving Energy for Better Health
By Shahir Masri - 10/10/11
How does flipping on your light switch affect your health?  To answer this, consider the way electricity is generated.  Typically, plants generate electricity using superheated water or steam to drive the rotation of turbines.  In much of the United States, power plants burn coal and oil in order to heat this water.  Known as fossil fuels, coal and oil unfortunately contain a number of toxic compounds such as mercury.  When plants burn fossil fuels, these chemicals are released into the atmosphere and in turn affect our health.  If you think you’re not at risk simply because you don’t live near a power plant, think again.
