There are a couple of disadvantages of Petroleum usage.

• First of all, as Humans, we should plan on the Earth lasting us for Millions of years in the future. It is our only home that we have that is able to support life as we know it. Other planets in our solar system may support Human life, but not like Earth. People are predicting not only catastrophic environmental changes in the next generation or so, but essentially permanently using up the World's total oil reserves in the next couple of generations. What are we going to leave our grandchildren? Our great grandchildren?
• Burning Petroleum essentially means adding CO2 to the atmosphere
• There is a lot of controversy about Greenhouse Gasses... but for the first time in the evolution of Humans, we can now make measurable changes in the Carbon Dioxide levels in the entire atmosphere of the earth. Now, the percentage is going from 0.03% to 0.04% or so, a 33% increase, but they are still small amounts. We'll likely run out of fossil fuels before we reach toxic levels of Carbon Dioxide in the atmosphere around 2%. But, should that be our goal?
• Information does, however, indicate that with the increasing CO2 levels, we are making permanent changes in our environment, changes that we have difficulty predicting the full ramifications of.
• Plastics, and many other things are made out of Petroleum Oils. Once it is gone, they will be gone for good.
• There are suggestions to fuel our appetite for Petroleum Fuels we should try sequestering Carbon Dioxide with Limestone, or other ways to re-inject it into the earth. Carbon Dioxide is essentially an ACID. I'm not sure I'm ready to start filling the earth under my home with ACIDS.
• Petroleum Fuels are dangerous to handle.
• Petroleum fuels produce some of the most noxious pollutants
• As far as socio-economic disadvantages, we are sending a LOT of US Money, labor, etc overseas to feed this need for oil. This money would be much better spent domestically. And, a huge part of our trade deficit boils down to petroleum.
• We've found a method to put ourselves at the mercy of people who don't like us.
• There are few monarchies left in the world. Right in the center of the richest oil in the world lies the most powerful Monarchy in the world. And, we just let them do whatever they want.
• Now, cutting global oil use to a fraction would devastate the Middle East... but, perhaps they need to look at changing their own economies too.

The safety precautions of a laboratory is entirely dependent on the subject what is it for. Whatever the laboratory is, there are several guidelines.

• Wearing the protective glasses all the time.
• Leave all your belongings away from your working bench.
• Do not eat or drink in the laboratory.
• Do not smell any chemicals or substances unless instructed.
• Do not light the Bunsen burner with a piece of paper.
• If anything is spilled, clean it immediately.
• Immediately report all the hazardous conditions to the instructor/invigilator or to the teacher.
• Be considerate of others (if anyone do an experiment nearby)
• Minimize the waste (including chemicals, filter paper etc.)
• Avoid reagent contamination.
• Leave all the reagents where they belong.
• Never put solid waste into sinks.
• Separate glass from solid waste.
• Return the excess re-usable material to the storeroom.

1.) Sun Tsu:

The author of The Art of War written between 544 and 596 BC, is enigmatic in terms of historical account and some suggest Sun Tsu or Sun Wu never existed. Whoever did exist that authored the book The Art of War is only relevant today in that that person is the author of a text that has profoundly influenced world events and continues to do so to this day.

2.) Socrates:

Considered to be the father of Western Philosophy he lived and taught between 469-399 BC. He is most noticeably remembered through the works of Plato, one of Socrates students. Their philosophies combined have influenced Western culture in their art, sciences and politics and their fundamental work is woven into the very fabric of Western thought.

3.) Jesus Christ:

On the opposite end of philosophical spectrum of Sun Tsu is another man who has been the subject of speculation on whether he actually existed, the Roman philosopher and chronicler of Jesus' time Tacitus, has Jesus written down as being executed as a political revolutionary in his history texts. The influence of Jesus and the New Testament that survives is every bit as noticeable as Sun Tsu's text and perhaps better known.

4.) Sir Isaac Newton:

In 1687 Newton published Philosophiae Naturalis Principia Mathematica and the world has never been the same since. In this book Newton described universal gravitation and the three laws of motion that laid the ground work for classical mechanics.

5.) Albert Einstein:

Born in 1879 this man rocked the world with his genius and is considered to be the most important person of the last century. Best known for his theory of relativity, he is responsible for over 300 scientific papers and is revered in the physics community.
