Coral Reefs worth saving
http://www.sciencedaily.com/releases/2013/12/131217155223.htm
The study about the Coral Reefs were held from 1999 to 2012. They have established the article in the November online issue called Public Library of Science. The scientists, Frazer and Jacoby studied reefs around Little Cayman Island, an area that is known for its healthy reefs. According to the Caribbean researchers has stated that the damaged reefs can recover. For 13 years of researching and studying Jacoby and Frazer had indicated that the reefs where it is located in the warm ocean temperatures, it led to bleaching and infectious diseases that reduce live coral cover by more than 40% between 1999-2004. The reef at the island is protected. Even the well protected one are suffering from the damage that human had done to them. Overfishing, runoff, coral mining, tourism, and coastal development are the treats to the coral reef. The researchers believed that if humans pay more attention to protecting them then it will also help the organisms that live in the coral reefs.

Population Growth Increases Climate Fear
http://www.sfgate.com/science/article/Population-growth-increases-climate-fear-4781833.php
The world population has reached over the earth carrying capacity. According to scientists at Standford University have warned that the Earth is reaching a tipping point. Due to all the technology and the way human genetically modified food, population are increasing all around. Humans are destroying the ecological life-support system and according to the Millennium Alliance for Humanity and the Biosphere at Stanford, children today when they reach middle age, the life-support system on earth will be damaged. An example of the reaching over the carrying capacity, the state of California. California is one of the most populated state in the world, one out of ten. There are many trash washing up on the coast, 157 endangered species, looming water shortages, 8/10 most air polluted cities in the country. The population of California is 38 million people which increased up 10 % in a decade. Population are doubling from the explosive birthrates growth. The government is creating a policies to encourage child-bearing.

Bite-Size War
http://www.nytimes.com/2013/09/30/us/in-florida-the-front-lines-of-a-war-with-mosquitoes.html?ref=pesticides&_r=0
Down in Florida, mosquitoes have always been huge problem. It leads to killed, sickened, bedeviled, annoyed, and outwitted many residents and visitors. In Florida, the place has warm weather with many swamps and marshland. Now, the bats abandoned the tower in Sugarloaf Key leaving the problems to the local people to take care of the mosquitoes. Dengue fever had became a problem in July of 2013. 20 people developed the disease. Locals in Florida are worried because these same flu was carried by the mosquitoes and it had occurred in 2009 out west. To find where these mosquitoes lay, it must be in small area that contain water. The locals tell everyone to get rid of any water that is expose to the environment in order to not let the mosquitoes reproduce. The use of DDT was banned in 1972 because back then they had drop large amount of DDT to kill the mosquitoes that live in the area. Michael Doyle, Florida Keys Mosquito Control District's executive director, stated it is harder to kill the adult mosquito due to that they are becoming stronger and resistant to the pesticide. Keys have been spraying pesticides into the car to let it float into small area where water are located to kill the larvae of the dengue fever.

Scotland Pledges new laws after hoursemeat scandal
http://www.foodmanufacture.co.uk/Sectors/Meat-poultry/Scotland-pledges-new-laws-after-horsemeat-scandal
Following the horsemeat crisis, there will be a new law in Scotland, scottist gov't has confirmed. It is to protect the consumers in buying the wrong product. Michael Matheson, a public health minister, has stated that, "We need to be able to trust the food we buy. We must know what is in our food and it must be safe to eat." It has appeared that consumer has no confidence in buying food from the Scotland and across Europe because of the hoursemeat scandal. But the government is taking defences and building up high confidence in Scottish red meat said Richard Lochhead. the Scottish gov't is giving more money toward the FSA Scotland in funding the meat testing and asking for them to watch how they label the red meat products.

3 new vertebrate species have been discovered on Australia's Cape York Peninsula
http://www.iflscience.com/plants-and-animals/three-new-vertebrate-species-isolated-millions-years-have-been-discovered
Dr. Tim Laman went to explore a remote mountain range on Cape York Peninsula in NE Australia and went to the rain forest near the boulder-fields, which is largely unexplored. Dr. Laman has discovered 3 new species that have been completely isolated for million of years which made them evolved into distinct species in their environment. The 3 species are Leaf-tailed Gecko, Shake Skink, and Boulder-frog.
Leaf-tailed Gecko was known as "exceptional", "extraordinary", or "exquisite" due to when the rain-forest was more spread out million of years ago. It hunts for prey at night and it is highly camouflaged and sit still for their prey to come near.
Shade Skink is discovered along with Leaf-Tailed Gecko. This specie is active during day when Leaf-Tailed Gecko is active during the night. It is referred as "saltus", which mean leaping due to the running and jumping hunting the prey.
Boulder-frog is a "rock-loving" specie. It lives during the dry season in the boulder-field and when the temperature began to decrease and become moister. It comes to the rock and feed and breed there.

Aquatic Biodiversity is Being Threatened by Pesticides
http://www.enn.com/wildlife/article/46112
Over the summer, the researchers has indicated that pesticide is dangerous to the aquatic life because it alter the ecosystems, cause nuisance, and spread disease. The decrease in biodiversity was due to several species being susceptible to pesticides and it is affecting the food chain. The species that are decreasing are mostly flies because their habitat is around littoral zone, meaning contact with both surface and water. According to ecotoxicologist, Matthias Liess, Pesticides always cause impact on the ecosystem, no matter what protection was created.

New Storm off Mexico's Pacific Coast
http://www.reuters.com/article/2013/10/20/us-mexico-storm-idUSBRE99J00P20131020
Acapulco, a city that was flooded last month, is getting threaten by a new storm coming off Mexico's Pacific coast. Mexico had suffered the worst flooding from Manuel and Ingrid's tropical storms last month. The tropical storm have killed more than 150 people and causing a lot of damage near $6 billion. Acapulco was one of the place worst hit by the event and the NHC had stated that the tropical storm is moving futher northwest at about 8 mph. The maximum sustained winds of depression is 35 mph. They expect the weather front to move slowly toward the coast near Acapulco in the next few days. Also, Mexico has no major oil installations.

Death of a Spruce Tree
http://esciencenews.com/articles/2013/10/03/death.a.spruce.tree
The climate change has a huge effect on the health of forests. The study showed that the forest fire is not happening which caused the dead trees to not be replaced by new ones. Also, due to the climate change, the growing of the tree is harder to estimate because they believed that the trees are storing more CO2. Bond-Lamberty had stated that "We need to understand forests in the long term, but forests change slowly and researchers don't live that long." This is correct because for some trees, it takes 100 of years for it to become a full size adult tree. In the NASA-led BOREAS project in 1990s, they studied the Northern Old Black Spruce site and collected samples from 3 different years between 2001-12. They had suggested that the slow-growth years was due to low rainfall and high temperature. Then, they found a bigger territories where the oldest trees started growing in the mid-1800s, and Bong-Lamberty stated that between the 5 years, the trees are dying and not being replaced. Also, the fact that the tree takes in CO2, the study shown that the middle-aged trees fatten up. As the period continued the world will get warmer and it will be a rotten time for the forest.

Longer Life for human leads to the loss of endangered species
http://www.sciencedaily.com/releases/2013/10/131009130122.htm
This study was published in September issue of Ecology and Society that as the population of human increases, birds and mammals are endangered. The study analyzed data from 100 countries and had explained that New Zealand, United States, and Philippines had the highest percentages of the endangered and invasive birds. Africa has the lowest percentage of invasive and endangered birds and mammals. It has a limit international trade, which gave less chance for biological invasion.

Researchers have generated gasoline from bactoria
http://www.nature.com/nature/journal/vaop/ncurrent/full/nature12536.html
The concerns about limited fossil fuels and the global environmental problem have focused attention on the develop biofuel from renewable resources. Researchers from Korea have engineered Escherichia coli stains that are capable of producing short chain alkanses, fatty acids, fatty esters, and fatty alcohols through the fatty acyl to fatty acid to fatty acyl-CoA pathway. They started off blocking the pathway of B-oxidation and to increase the short-chain fatty acids by deleting the fadR gene. Then, a modified thioesterase was used to convert short-chain fatty acyl-ACPS to the correspinding FFAs. The final engineered strain consist of nonane, dodecane, tridecane, 2 methyl dedocane, and tetradecane, which chain with small amounts of hydrocarbons.

Turning Plastic Bags into High-Tech Materials
http://www.sciencedaily.com/releases/2013/09/130925102651.htm
University of Adelaide researchers have created a way of turning waste plastic bags into a high tech nanomaterial. By transforming the waste materials through the nanotechnological recycling, can help decrease the environmental pollution at the same time as producing high added value product. The idea of this process was by PhD student named Tariq Altahi. The process of producing the high tech nanomaterial is catalyst and solvent free, meaning that it can be used without generating poisonous. So far, the plastic bag that was recycled had been used in many industries like in electronics. sports equipment, batteries, sensing devices and wind turbines.

Where will it erupt? Yellow Stone Super Volcano
http://news.nationalgeographic.com/news/2012/09/120920-yellowstone-supervolcano-prediction-volcanoes-science-environment/
Geologist had predicted that Super Volcano will erupt at the center in 1/3 paraelle fault zones running north-northwest across the park. Guilaume Girard stated that small eruptions will occur more, but the major eruption will probably occur is less than one in ten thousands. Girard's team had study the titanium content of the lava flows and that it is risen very quickly from the magma chamber sone 4 to 7 miles deep.
