U.S. is Second Highest for CO2 Emissions

Carbon Dioxide(CO2) is a chemical that exists in natural sources all around the world.  However, the CO2 emissions that are created by burning certain kinds of fuel are very harmful.  These types of fuel that create such awful emissions range from gasoline in our cars to coal in coal burning power plants.  This is a problem because as we are trying to find cheaper and cheaper ways to produce energy for our daily lives coal is the cheapest option.  Coal is also one of the most dangerous options because it emits the most Carbon dioxide.  CO2 emissions from these and other sources are one of the leading causes of global warming.

According to Wikipedia.com in 2008 the United States was the second leading contributor to CO2 emissions. The only country with more CO2 emissions was China. Wikipedia also states that China's CO2 emissions in thousands of metric tonnes from the year was 7,031,916 and the United State's was 5,461,014.  Let me put that in perspective for you.  These numbers are in thousands of metric tonnes.  One metric ton is equal to 2,204.62262 pounds.  So if you multiply that big number by 1,000 then multiply your product by the emission numbers given for China and the U.S. you will have the actual amount of CO2 emission for the year.  Now, I'm a math major so I'm used to seeing a lot of numbers but these numbers are a lot for me to wrap my head around.  Consider this; the average male in the United States weighs 191 pounds while the average female weighs 164 pounds.  Now if you go back and think about the numbers for the CO2 emissions and compare them to the average weight of an adult person these numbers should seem outrageously huge.  I'm not going to propose that we should just stop using any form of energy to avoid emitting CO2 because that would not be realistic but I do think that we should cut down on some of the things that we do in order to cut down on these emissions and make our planet safer for all of us.  There are so many small things that we could do that would make the biggest difference.

Water pollution in Developing Countries

According to recent research we are living in a world of water crises.  An article by Mingcaqian Li of East China University states that recent research shows that many health problems can be traced back insufficient or polluted water resources.  This problem is occurring in multiple countries around the world and it is a very serious problem.  Many of the countries where this water deficiency is taking place are underdeveloped countries.  The countries cannot continue to develop without adequate water supply.  Therefore it is hindering the survival of the people not only because they do not have an adequate amount of clean and safe water but also because the country cannot develop any further to support the population.  There are many reasons why this crises is taking place, ranging from corporate pollution to things as small as individuals throwing out there McDonald's napkin after they've finished their BigMac.  It's absolutely sad that this problem even exists, that we don't care enough about the environment that we live in and the people around us to change our ways.  If we all made small changes to certain things that we do like throwing out a napkin after our fast food lunch this would make a HUGE difference in water quality all over the world.  Kids should be able to swim and play without worrying about getting sick from the water and parents should not have to worry about the water that they are giving their kids to drink.  I believe that each of us can change something about what we do in our daily lives to make the water supply safer and plentiful for everyone.

Disappearing Rain forests

It is very sad that one of the world's most beautiful and most diverse ecosystems is disappearing more and more every year.  According to rain-tree.com 14% of the world used to be covered by rain forests.  Now, only 6% of the world is rain forest.  Also according to rain-tree.com experts are saying that the last of the earth's rain forests could be gone in less than 40 years.  To me that is a chilling statistic but it is a reality that we must face.  People are willing to destroy these beautiful parts of the earth because the only value they in the rain forest is the value of the lumber they contain.  However, if rain forest continues a large fraction of the earth's species of plants and animals will die off.  But all of that life is worth destroying as long as we get the lumber right?  I don't believe so. Rain-tree.com puts this into perspective by stating that experts believe that we are losing 137 species of plants, animals and insects every day due to deforestation!  I must be honest.  I had no idea that this was this much of an issue.  I never really thought about it but now that I know these facts all I can do is wonder why we continue to let this happen.  These are beautiful lands containing gorgeous plant life and tons of different animal species and we are just letting them be destroyed.   I believe that we must stand up for these living things that cannot stand up for themselves and put a stop to rain forest deforestation before it is too late and they are all gone.

What are you drinking out of?

This week's blog post is inspired by fast food restaurants.  It is not for their food but rather the cups that they serve their drinks in.  Most fast food places either serve their drinks in paper, Styrofoam, or plastic cups.  I wanted to examine which of these is the cheapest to produce and which is the best for the environment.  This may not seem very interesting to some but considering how often people visit these kinds of restaurants I thought it was worth looking into for our environment's sake.
According to genexe.com plastic is actually the cheapest of these to produce, costing $11.00 for 1000 while Styrofoam costs $25.00  for 1000 and paper cups cost around $80.00 for 1000.  This kind of shocked me because I thought that paper would be the cheapest but I was wrong.  According to genexe.com paper cups(like McDonald's uses) are not only the most costly but they are the worst for the environment.  They result in almost twice as much CO2 emission and energy consumption over Styrofoam and plastic.  Also stated in the genexe.com article, if paper cups have a wax coating on them, which  many of them do, they are not recyclable.  Therefore, paper cups seem to not be the best option environmentally or economically.
Another option, Styrofoam is cheaper to produce and probably more efficient because it is a much better insulator that paper or plastic.  However, genexe.com states that Styrofoam can break into small pieces very easily and these pieces can be hard to breakdown and can be harmful to people and animals because of the chemicals used for it.  In many ways plastic appears to be the best option.  Genexe.com says that this is because most plastics are recyclable and even if they are not they can be used as fillers in other products.  More research will have to be done of course, and I am interested to look further into which choice is best but based on my current research I'd say that plastic is your best bet!
