I chose this summary due to my interest in fishing and how it has an affect on our environment. Im interested in knowing what are the possible causes and effects these two attributes have on each other and how it can affect us as humans.
After reading through you summary, I would have to agree with you that the only way that we can enforce change and restrict these measures is by enforcing laws and having a program ran under government control. I cannot see any other way to make change happen other than that. Having fisheries controlled by the government is in my opinion the most optimal and efficient way that we can sustainably manage these fishing industries.

I decided to chose this article due to my interest in the causes and effects that come into consideration when talking about climate change, and how it could be or could not be problematic and if it is something that we as humans should be worried about.
I would have to agree with you, this summary was well written and went through all the main points in order to understand the situation. It is true that we as humans need to be more patient and aware about the process. If we take more care of our envionment we could possibly see some changes and a reduction in change in climate. The problem with this is that humans do not have the patience in order to change their way and standards of living for long term impact. Humans are used to having something done and having immediate impact, but this is not the case for this situation. Humans will need to adapt to a different standard of living in order to have the best and most successful way of reducing climate change.

Reading this article, I realized a lot of things I did not knew before. When it says that in 2048, overfishing will create extinction I was shook. This is in less than 50 years that means that were going to face serious economical consequences very soon. Aquaculture is a new topic that I learned from this article and this is why I found it even more interesting. I had heard about aquaculture but I never realized it could be a great solution in South China for example. But I don’t think that it means we should strop caring about the ocean. It is sad to realize how much we use our resources badly and we don’t seem to understand how important the ocean is. This article is important because even if for now it concerned Asia, it will eventually concern more people around the world because the extinction of some species will have negative impacts on everyone.

This article was really good and pertinent and I totally agree with the fact that this issue should be taken seriously worldwide before it is too late and we don't even realize it.

I decided to choose this topic due to my interest in what is the natural ecosystem change. I find it interesting to find the different ways that humans are affected through natural disasters and how they are caused.
As the writter wrote, I would have to partialy agree with them. I believe that there could be many different ways we can slow down these natural disasters or could stop rather than not being any. I do not think that it is immossible, but it is hard and is nearly immpossible unless we as humans being to contribute to the environment help stop pollution o make our ecosystem better, which may reduce the amount of natural disasters that are caused. I could see as to why you believe that their is little to no solutions due to them being "natural," but in my defence I would have to say with help of the rest of the world it could possibly reduce the amount of natural disaster and/or stop them.

I found this article really interesting and appropriate because when we talk about climate change we often talk about the Artic and the ice that is melting but this article shows us what is going on in the Sahara Desert. It is a really informative article and the data is collected since 1923 so it is really structure. I never really noticed but the fact that the Sahara Desert is expending is making some people lose land. I really like how you resume the article but you should try to put more example! What is great about your article is that the video in it is super interesting and it helps to understand!

This give us another perspective of the issues, when they say that the weather in Africa get warmer I realized that climate change is not only affecting the Arctic for example.

I think the article is a very relevant article as it exposed what we are doing to our planet, more especially to the wildlife. Each and every single animals have a serious role in our ecosystem and we take them for granted too often. You summary is good and it is actually full of interesting informations! I liked that you exposed how selfish humans are towards the situation and I like that you are really concern about the issue. Thinking that there is only 23% of wilderness left is crazy and I agree that governments should take more actions to preserve the wild life.

After reading the text and the article I got kind of sad because the wildlife is beautiful andI remember that Learned in biology and the environment managed is own self and how it can be bad to disturb that and I think it should be something that people realize to preserve a beautiful planet.

I am choosing this topic due to my concerns about our population and how we can or how it will be controlled. It's interesting seeing all the different factors that have to be taken into consideration for our population to withstand with our resources.
As Alexandra said, the real issue is maintaining our resources for the large population growth that we have, and that there is no sort of way of stopping it unless we implement some sort of population control. I am not entirely sure if you agree with the author that the only ways to control the population are by depending on the government and society as a whole to educate others about the problem, but I am assuming you do. On the other hand, I do believe that you have the correct perspective on the issue, such as people are not realizing the problem, because they do not see it. All in all, I believe the best way to this solution is by implementing laws to control births and educating those who are not aware, but how is the question.

This article was really interesting to me! I never noticed how much water we use for cereals or beef. The statistic surprised me and even scared me as 1000L of water for one kg of cereals and 43 000L of water for one kg of beef is enormous! Humans consume a lot of these two product and I am concern that if we are not more careful we will run out of water one day. A lot of countries like Uruguay, Argentina and Hong Kong consumed more than 100kg per capita of beef only in 2016. This is really scary because this article show us the correlation of water and what we produce! I think everything you say is really true, there is a serious issue and we must do something as a society to be more careful because we seriously could have a shortage of water. If everybody consume less meat I believe we could see a real difference in the future.

The impacts of meat consumption on the environment are of great concern as you mention in your article. Nevertheless, they are often overlooked by environmentalists. Hence, I congratulate you for having taken the time to explore this issue.

First, I completely agree that food production takes a large portion of the US land area. As a matter of fact, this is a global problem. Specifically, the livestock production takes 70% of all agricultural land, and 30% of the Earth’s global surface (Ilea, 2). Thus, one of the main causes of global deforestation is animal farming (Ilea 8). Indeed, large areas are necessary for animals to graze, and for the production of their feed (Ilea 8). For example, from 1990 to 2000, the Amazon rainforest lost “an area twice the size of Portugal […], most of it to pasture” (Ilea 8). Similarly, 50% of the global production of corn and 80% of that of soy is intended to feed farm animals (Ilea 8). As you partly noted, meat production can, as a result, cause biodiversity losses, soil erosion, and deforestation (Ilea 8).

However, while reading your second paragraph I did not see how your argument proved your conclusion. Indeed, while you state that the US food production, may it be for meat or for plant, use a large amount of energy and is not sustainable, you conclude that a vegan diet is much more sustainable than a meat-based one. Although your conclusion is reasonable, the statistics you provide do not prove it. Nevertheless, in addition to the other environmental consequences aforementioned, the livestock sector does have a significant impact on global warming. As a matter of fact, the livestock sector is responsible for 18% of the global greenhouse gas emissions, which is more than those of all transport (Ilea 2). More specifically, meat production is responsible for 68% of anthropogenic nitrous oxide emissions, 64% of anthropogenic ammonia emissions, and 35–40% of anthropogenic methane emissions (Ilea 4). While methane and nitrous oxide respectively have a global warming potential 23 and 296, nitrous oxide also contribution to the ozone depletion and ammonia plays a significant role in the acidification of rain (Ilea 4).

Similarly, meat production also consumes much more water than the production of cereal, as you noted. Nevertheless, the statistics you provide do not match those I found. Indeed, you mention that producing 1 kg of animal protein requires 100 times more water than 1 kg of grain. What I found, however, is that the production of 1 kg of meat takes from 2.5 to 20 times more water than the production of 1 kg of grain (Ilea 9). As a result, “diets based on meat from grain-fed cattle may take two times more water than pure vegetarian ones” (Ilea 9). Nonetheless, this is a real problem, especially with increasing water shortages that are expected; in fact, “64% of the world’s population is expected to live in water-stressed sectors by 2025” (Ilea 9). Furthermore, the nutrients from livestock’s manure are important sources of water pollution (Ilea 9).

Finally, the rapid population growth will indeed make all these problems worse if no changes are made. The population of the United States is indeed expected to increase, as the projections are now expecting, to 447,883,000 people in 2100 (United Nations, 28).

Hence, while some suggest that the population growth should be controlled, it is certain that developed countries’ consumption of animal products will need to be decreased (Ilea 12). In fact, if the global trend is not changed, the world livestock will consume as much as 4 billion people by 2050 (Ilea 12).
