Discussion board 5
Instructions: There are a lot of articles that you can find on the web (e.g. Science Daily, Discovery News, BBC, CNN, Nature, Science) about groups of organisms that are bacteria, archeans, protists, and plants or you can look for articles on conservation and ecosystems, biomes, and climate change. For this discussion you need to find one of these relatively current (within the last year) articles that relates to Chapters of this section. When you have identified the article you need to do the following that involves several postings by you.
- Your first post is about the article:
- write at least 300 words in length about the article which includes-
- A three- four sentence summary of the articles main point or purpose of the information.
- A short discussion on how the article specifically relates to the class and/or chapters we are studying
- A statement about why the article is important and what you think about the material in the article.
- Any questions you have regarding the article
- and you MUST have the url to the article attached to your work. It needs to be in the form of a link so I and other students can find and read this article.
- Your second, third and fourth post:
- Read and respond to at least two of your classmate’s articles. Your third and fourth post can be answering responses to your initial article, or responses back to your questions or comments to other students, or you can respond to other students who posted to your article.
ECOSYSTEMS AND BIOMESby Yujie Yang – Thursday, 1 July 2021, 10:01 PMNumber of replies: 0
The article “Habitat and species loss leave just 3% of world’s land ecosystems intact, study suggests” mentioned that just under 3% of the world’s land remains ecologically intact, with undisturbed habitat and minimal loss of its original animal species. The research mentioned that human damage to habitat shows that animals have disappeared from their actual ranges or are too low in number to maintain a healthy ecosystem to reach its conclusions.
The article is essential because it shows how humans impact ecosystems and biomes. The impact that human causes on the ecosystems had led to many animals to lose home and their habitat. We think that 3% is a lot because the number of wild animals in the world is way less than humans, but wild animals used to have more land to live on until we started building and disrupting their lives. This article is essential to this class because causing damage to the ecosystem may cause many nearly extinct animals to become extinct. I think this article is very important in raising awareness of animal extinction and damage to animal habitats. Still, many people today don’t care about animal extinction because it will not impact our lives.
We couldn’t do anything to stop animals from extinction, but there are many organizations built for treating and breeding nearly extinct animals. Ordinary individuals like us can’t contribute a lot to preventing animals from extinction, but we still can do many things. We can reduce our carbon emissions by not driving every day and voting for individuals that will help prevent animal extinction. I don’t think animal extinction is a massive issue because organizations like “save animals” are doing great work that help keep those animals away from extinction. We should support these organizations and also stop hurting the environment because we don’t want extinction to happen to humans.

EXPLORING MARINE PLANKTONIC ARCHAEAby Zeqi Wang – Thursday, 1 July 2021, 7:38 PMNumber of replies: 0
his article is about Archaea, and it is very relevant to what we learned in class. Since Archaea was discovered, people have always believed that they live in extreme environments such as salt lakes and some extremely hypoxic places. But later this statement was overturned. It was found in human mouths, skins, oceans, etc. This article is about Archaea on marine plankton. This article introduces the origin of methane in the ocean. Many people think that methane on the seafloor was born from archaea, but this article learned that archaea do not produce methane. This type of archaea is a substance called methyl phosphonate, and methyl phosphine Methane is formed as a by-product of acid salt under the action of aerobic bacteria. From this, we can see the importance of archaea. Its role may exist in all aspects of the world, and there are many types of archaea, and the coverage is particularly broad. Their genes are still very active, and their genomes are very diverse, so they are of great significance for biological research, especially genes. And archaea are involved in the cycles of carbon, nitrogen, and sulfur on the earth, which means that archaea maintain the stability of the ecosystem, especially the nitrogen cycle in the ocean, and archaea are the main participants. It is a pity that planktonic archaea are difficult to cultivate in the laboratory, which has led to very slow progress in the study of archaea. Until now, no clear research on marine archaea has been reported. Of course, there has been considerable progress in the cultivation of certain marine archaea, and large-scale collection methods are still the main plan for culturing archaea. I believe that soon, humans can cultivate and study archaea in the laboratory. This will be one of the great developments in biology. For humans, understanding paleontology is very helpful to understand ecology and evolution.

CLIMATE CHANGEby Yuxin Zhou – Thursday, 1 July 2021, 6:27 PMNumber of replies: 0
Climate change has always been a topic many environmentalists and people talk about during the last couple of years. The article “Climate change: Why action still ignites debate in Australia” mentioned that Australia’s government refuses to pledge net-zero carbon emissions by 2050. Australia cannot achieve zero carbon emission because Australia is one of the world’s most significant coal, iron-ore, and gas exporters. The country will lose a lot of money if they are planning on achieving zero carbon emissions.
This article is very important to this class because we learn how climate change might change the earth’s environment. Experts say that a 1.5 degree celsius average rise may put 20-30% of species at risk of extinction, and if the planet warms by more than 2 degrees celsius, then most ecosystems will struggle. 1.5 and 2 degrees seem like a small number for us, but it will take many years to raise the global average temperature by 1 degree. We shouldn’t don’t care about climate change because of the rate of carbon emissions now, and we will raise the global temperature faster than we expected.
I think the material in the article is very good at reminding people that the earth will be inhabitable after many years. Australia has been dramatically affected by climate change because of the forest fire that happened a couple of years ago. I believe that we cannot achieve net-zero carbon emissions because our world was based on emitting carbon fuel to survive. Planets can’t stay if we give up all carbons. Reducing carbon emissions will be the best way to prevent global warming and invent new technology that will eventually replace carbon, for example, electric vehicles and hydrogen cells. I think global warming isn’t a problem now, but we have to raise awareness of global warming. I have one question: what is the exact time that global warming will affect many species on earth?
