Week 6 
University of Barcelona. "Global change threatens high-mountain plants able to adapt to new environmental conditions." ScienceDaily. ScienceDaily, 21 November 2016. <www.sciencedaily.com/releases/2016/11/161121112315.htm>.

 This article is about the plants that are at the top of mountains and it explains how they are the most affected ones from the global  warming. With the global warming the tempearture of the earth rises and this affects most of the living things in a negative way. The higher the place of the plant is, the more the sunlight that it gets with a narrowe angle and so it gets affected more. In this artticle this is stated. The solution to that prblem would be planting the plants that will require more sunlight than normal to the top of the mountaiins so  a sunlight that would normally damage the plant will actually help these species to grow. I find this article related to our topic ''Zonation'' since we studied the living things through an environmental gradient in that topic. 

Week 5

PeerJ. "Three new species of miniaturized tropical salamanders are already endangered." ScienceDaily. ScienceDaily, 15 November 2016. <www.sciencedaily.com/releases/2016/11

A new spevies has been found just these days and not much after its discovery, it is stated that the species is going extinct. The reason behin this extinction is human behaviour unfortunately. They are identified as ''Endangered or Critically Endangered by the International Union for the Conservation of Nature.''  As a class we have studied endangered species and how they are identified as endangered or critically endangered.Also we have studied the human's effect on making a species go extcint and how the cause-effect mechanism works. The extinction of these species  oıuld probably cause a gap in the food chain or food web and will reduce the biodiversity so the resiliienc eof the ecoystem that they are in. To stop this, what we can do is take some of the salamanders and artificially breed them and make them reproduce rapidly and then release them back to their own nature. Also the acts that causes these species to die should be quited. 

Week 4
University of North Carolina at Chapel Hill. "Pollution emitted near equator has biggest impact on global ozone." ScienceDaily. ScienceDaily, 8 November 2016. <www.sciencedaily.com/releases/2016/11/161108085028.htm>.

In this article the importance of the place of emmision is given and it is stated that the place is more important than the amount of emmision.The researchers claim that the emmisions in the equator are causing  more damage to the ozone layer. Their claim is supported with evidence this is why I believe we must take  good care of the emmisions on that region especially. We need the ozone layer to protect us from  a specific kind of UV light and the damage on the  ozone layer  might cause such bad effects on human and on the nature. I find this article related to the 6th unit in which learned about the ozone layer , its uses and what happens  if it is damaged. Also the formation of ozone again , which we learned in the 6 th unit might not be properly done due to the emmisions on that specific region and that might be the reason why regional emmisions are important in fighting the damages on the ozone layer.

Week  3 
University of British Columbia. "Ocean acidification study offers warnings for marine life, habitats." ScienceDaily. ScienceDaily, 21 November 2016. <www.sciencedaily.com/releases/2016/11/161121130638.htm>.

The oceans being acidified causes the biodiversity to lower down and this is a real problem since an ecosystem with low resilience and low bodiversity can be damaged easily.My solution to this  issue would be to quit using fertilizers which then be transmitted to the oceans. Also the usage of CFC emmiting products should be restricted so that there will be less acid rain  and  the oceans wont be acidified that much. I think this article is related to the 6 th unit in which we leaarned about the ozone layers, how acid rains  are occuring and so. Also the topis that we have lastly covered such as eutrophication and water pollution are related to this article too. 

Week 2
University of East Anglia. "Over-hunting threatens Amazonian forest carbon stocks." ScienceDaily. ScienceDaily, 25 January 2016. <www.sciencedaily.com/releases/2016/01/160125155741.htm>.

Over-chasing large mammals in tropical woods could cause negative  environmental change. Tropical forests overall store more than 460 billion tons of carbon. Analysts concentrated on the effect of over-chasing on carbon stockpiling over the Amazon - the biggest woodland on Earth. They found that effect could be huge: an anticipated 313 billion kilograms of carbon not being ingested. The economic  estimation of such a loss in worldwide carbon markets could cost US$13.7 trillion.

Overhunting affects the environment very bad since it damages the food chains and food webs. I have just learned about a damage  about the carbon stocks however I can truly relate why the absence of creatures in secondary or tertiary trophic levels will cause a decline in the carbon stocks.I relate this with the second topic of our curriculum since we have covereed how living things are related to each other and NPP,GPP, CO2 release of organisms. I think the overhunting can only be gone with restriction and strict rules, taxes, punishments.

Week 1
Cornell University. "Marine microalgae, a new sustainable food and fuel source." ScienceDaily. ScienceDaily, 21 November 2016. <www.sciencedaily.com/releases/2016/11/161121131638.htm>.

Taken from the base of the marine evolved way of life, microalgae may soon turn into a top-level contender to battle an unnatural weather change, and additionally vitality and nourishment weakness, as indicated by a study by analysts connected with the Cornell Algal Biofuel Consortium, distributed in the journal  Oceanography.

I personally think that this can be a god way to support the global need of fuel however I am concerned with the efficiency of this production. Also the article includes the information that to produce enough for the global need of fuel, an area of 800,000 miles will be needed. It might be hard to maintain such area and countries might fight for the microalgae this time and it may change the way the countries fight.However it is such a better way to produce for most places since it does not require freshwater.  I  liked the the thing that as a byproduct protein is given by the production and it will be a food security for the planet. I find this related to the food production systems in our ESS curriculum.I think this article should be released in more popular journals so that the world will hear about such way to live sustainably and so people related with IB can see this and add this to the curriculum on the food production systems.
