Climate Change: Scientists Witness Greenhouse Effect in Action (A)
In this article, scientists study the greenhouse effect and its results on Earth. It describes a study in which scientists prove that pumping carbon dioxide into the atmosphere is warming the Earth's surface. Scientists tracked the infrared radiation that was coming down to Earth's surface. This radiation is absorbed by greenhouses gases, which then scatter is to all different places, thus causing increasing temperatures. Scientists studied the levels from 2000 through 2010 and discovered that the amount of carbon dioxide rose by 22 parts per million, which refers to the volume of carbon dioxide molecules in every million air molecules.
I feel that greenhouse gases and this article relates well to things that we have covered in Environmental Science, especially our new plant project. In my opinion, the rising levels of carbon dioxide help plants in many ways. Plants take in carbon dioxide in order to perform photosynthesis. By performing photosynthesis, plants release carbon dioxide, which humans need to breath. Therefore, these rising levels help humans, too. The more carbon dioxide that is in the environment, the more photosynthesis that plants can perform and the more oxygen that will be available for humans to breath. This article provided an interesting study on greenhouse gases. While many people think of greenhouse gases as negative, I believe that they are beneficial and necessary for plant, animal, and even human lives.

Oregon Chub Becomes First Fish Taken Off Endangered List (A)
The Oregon Chub has officially become the first fish taken off thee endangered species list! This article explained how this fish, added to the endangered species list 22 years ago and updated to threatened 5 years ago, has officially repopulated and gotten taken off these lists. By meeting key needs such as a safe place to live, the state director for Fish and Wildlife has managed to provide this species of fish with a safe environment, where they have thrived and grown, though a watchful eye will still be kept on them.
I feel that this article relates well to our lesson on endangered species. I agree that the fish still need to be watched carefully and cared for, yet I believe that the species will only continue to thrive and grow. Often times, species that are on the endangered or threatened lists are at a high risk for extinction. This article, though, proves that sometimes happy endings are possible!!

Canadian First Nations Seek to Protect Forest Homeland (A)
This article describes the First Nations, the national people of Canada, fight to gain back land taken from them and protect it from people that want it solely for natural resources. This Canadian land is home to a boreal forest. This forest contains many trees that, if cut down, will release an immense amount of carbon dioxide that will add severely to global warming.
This article relates to our lesson on habitats, as it focuses on the protection of a boreal forest. The First Nations people got their land wrongly taken, and now that it has been returned, they need to protect the forests from being destroyed in order to get natural resources. While I believe that obtaining natural resources is important, these resources can be gotten from alternative places so that the boreal forests can be protected. If we work together to compromise and find alternative options for gaining resources that are necessary to our survival, the world will become a better place and find the best option for the good of all people.

New U.S. Dietary Recommendations First to Consider Environmental Impact (A)
This article describes how health professionals are beginning to consider of foods impact the environment, whether it be from how they are grown, packaged, delivered, or many other things. The article states that new dietary guidelines will be decided on March 8, and these healthy food guidelines will be relates more to the food's impact on the environment than ever before.
This is important because it is a topic that often goes unnoticed and unconsidered. When people eat food, they usually focus on the nutritional value of the food, rather than on the impact the food has on the environment. It is important to consider how the food will effect the environment, and seeing that health professionals are now shifting part of the focus to this means good news for the environment. This is especially significant to our class now, as we are discussing food. Next time you choose what type of food to eat, don't consider just its nutritional value, consider its environmental effects, too!

Reducing Consumer Food Waste Could Save $300 Billion Yearly by 2030 (A)
This article discussed how reducing wast could save several billion dollars each year. As stated in the article, much of the worlds food waste comes from developing countries. This is due to their lack of technology and resources such as refrigerators and freezers. Without these types of things, it is nearly impossible to minimize food waste. However, if these countries had access to these things, the amount of waste would decrease, and billions of dollars would be saved yearly.
This article is significant to our class because we recently discussed developing countries. These countries are poorer than developed countries, so they are unable to obtain the necessary things in order to reduce their amount of food waste and save money. As residents of a developed country, it is our job to work together to help these countries achieve the necessary means, because saving money would benefit our world as a whole.
