“As Humans Change Landscape, Brains of Some Animals Change, Too.” By Carl Zimmer
A. Biodiversity
B. According to Scientist Emilie C. Snell-Rood, small mammals’ brain size has increased over the past century. These small mammals include bats, voles, mice, and shrews. A new study has measured mammal cranial size and discovered that animals living in cities and suburbs have an increase brain matter of 6 percent. Dr. Snell-Rood concluded that the brain mass increased significantly due to the necessity to travel further for food while still being able to navigate home. Scientists hope to extend this research by breeding large-brained animals with their small-brained cousins to identify and study the genes that involved in brain size.
C. I chose this study because it seemed like a very interesting subject. I was skeptical at first that their brains were enlarged by their own accord, not in laboratories or by scientific experiments. It was very eye opening that these animals were evolving, and only in the very immediate years. I think that this would be a more relative way to teach Charles Darwin and evolution to children in the school systems.

Summary: The Fuhe River in China was bombarded with thousands of dead silver fish that almost clogged the river entirely. After further investigation the cause of all these deaths was determine to be high levels of ammonia discharged by a chemical plant in a city just outside of Wuhan. Water samples showed that the levels of ammonia were well past the national set standard. The norm would be around 0.2 milligrams and from the tests the amount of ammonia showed to be around 12 milligrams per liter. The river had been recently affected by drought which lessened its chances to sift out pollutants and the plant was ordered to stop production until the river was clean and the excess waste was under control. Water quality issues have sprung up in china and in a 2009 study by the Ministry of Environmental protections of all the lakes and rivers they monitor, 30% are labeled as being polluted.
Reaction: After reading this article I was shocked that waste from a plant killed that many fish and had that much effect on the neighboring towns. Waste from plants like these, which are everywhere, dump waste into rivers every day. It makes me wonder if similar situations like this happen more often and we just don’t know about them. If I was affected by this river being polluted I would want someone to take action so I’m glad they ordered the plant to shut down till they got this issue under control. However they should also do everything in their power to make sure this doesn’t happen in the future and maybe find some means to reduce the amount of waste that they pollute the river with or just find some other place to put the waste…maybe even reuse the waste somehow? Its important for people my age to be aware of this because even though China may be one of the most populated places on the planet, if we keep producing like we are now we can end up with just as many people as them and have the same problems. We can learn from their mistakes.

The EPA certified the new 2014 Honda Accord Hybrid with a 50 mpg rating in city driving. This is a big mile stone for mid size sedan hybrids. It was only a few years ago when only small bodied hybrids had this capability. This rating is so good, that the 2014 Toyota Prius only gets 10% better mpg. This is good news for Honda. Research shows that customers want larger cars, with “Prius” type fuel economy. This should secure the Accord Hybrid has the top contender for future hybrid buyers. Honda claims that they have also completely redesigned the car from last years model. They have introduced a smaller, lighter, lithium ion battery. They have also reduced the engine size to the equivalent of a 2.0 litter I4 while still maintaining above average horse power. One downside to the car is that its starting price is $39,780, a full $18,000 more than the regular Accord.
I chose this article because it affects me. My dad sells Honda. Personally, I want Honda to makes the best cars on the market so that my father sells more of them, making us more money. I like cars a lot too.

Plastic Pollution in Our Oceans
A) Environment, pollution and human health
B) It astounds me how much litter we put into the ocean, the majority of it being plastic. Animals are dying (the pictures of seals and penguins with plastics wrapped around their necks just kills me), beaching are becoming filthy and humans may even be at risk health wise. The debris stick around for years on end with monstrous effects, especially when ingested by animals because some compounds of the plastic waste can cause cancer and disrupt hormones. That effects the human population because we then catch and eat sickly fish. Not only is this issue dangerous, its costly to try to fix. Beach clean ups cost millions of dollars, so why cant we just stop dumping the waste in the first place? We already know the harmful effects.
C) I chose this article because it is a commonly known issue and I already know much about it. Ie heard before that humans waste so many plastic bottles that they could wrap around the earth, end to end, some odd number of times. Just ONE time was astonishing to me! Imagine how much of that is in our waters? It also breaks my heart how badly marine life has been fairing lately. From seals to polar bears (the poor polar bears!), marine life is all around a struggle, either due to pollution and waste, or climate change and melting ice.

B. Researchers from Wake Forest University discovered that Peru's Cloud
Forest are indangered because of warming in the climate. The plant species
in The Peruvian Cloud forests thrive in wet climates and the recent
increase in temperature is harming them. This warming is causeing these
plant speciese to lose 53-96 percent of their population. Right now the
scientest are working on moving the plants further up the mountain where
its colder so they can survive.
C. I read this article orginially because the idea of a cloud forest sort
of amazed me that the forest was so high up it was in the clouds. The fact
that these species are losing into the 90%'s of their population is
extremly shocking and bothersome because that means theyre almost extinct.
The scientist are talking about moving the plants higher up the mountain
and hopfully thatll work but i dont know if itll be a long term solution.
I would really like to know how they plan on moving the plants sthat are
already rooted into the ground.
