The sea has many problems, some being the destruction of coral reefs, water pollution, global warming, acidification and also overfishing of sea creatures. Although all of these may take long to reconstruct if it is at all possible in order to save the ocean, the goal is to do something about it and start somewhere to make the difference. Overfishing is a big problem because this reduces the amounts of species in the ocean which also has reduced the fisheries of their stock by up to 90%.

A team of researchers discovered incredolous amounts of cadium and arsenic in the air of the hotspots of Portland, which can prove hazardous to human health such as development of anomalies in children and cancer. During the investigations of these hotspots, the same team of researchers found an unlikely indicator of highly polluted air: the moss named Orthotrichum lyelli, which is not only cheaper than the current method they are using, but also much much more economical.

Experts in India claim that the air pollution would affect the country's plans to use solar pannels. They stated that it would affect the plans ina  negative way; "Experts said solar power generation is impacted by the dimming effect, a phenomenon wherein the amount of solar radiation reaching the earth's surface decreases due to the presence of pollutants in the air that absorb solar radiation and reflect it back into space.". This is bad news for solar powered plans and also a sign that solar powered energy cannot solve every problem.

Deforestation is a major problem due to the different kinds of living species and plants that are dying. Although some of the causes of deforestation are done by forest fires, humans are the main problems. With logging in place this is a main cause of the issue. People harvest lumber, usually bringing the wood to sawmills or to a lumber yard. Logging causes the forest floors to dry out which creates a higher risk of forest fires. Calculations have been done to see how much logging has damaged undisturbed forest each year in 1996 and 1997, which was 10,000 to 15,000 km2.

It is known by a lot of people that Brazil was a very bad example of deforestation in the 1990s. In this period, an area the size of Belgium was destroyed in the Amazonian rainforest every year. Fortunately, Brazil has found ways to break the vicious circle in which it was and its deforestation fell by 70%, going from a 19500 km2 per year in 2005 to 5800km2 in 2008. If it had continued at this pace, a surplus of 3.2 billion tone of CO2 would have been released. This is why Brazil play an important role in climate change.

All around the world, it happens that certain countries have difficulty with their waste management. In fact, this major problem in different location can be dangerous for certain humans being health. Some, can be affected by what we call; hazardous waste. This kind of garbage is most of the time composed of toxic chemicals that can come from factories and can be very dangerous for human health. So, a study has been done on the subject to know exactly how bad waste management can affect health. For this study, they analyzed population that are exposed to this said hazardous waste.

Geoengineering consists of using large-scale technologies to affect the Earth’s climate (Wood 1). The first set of geoengineering strategies consists of blocking the sun’s heat from getting to the Earth (Wood 3). For example, Stephen Salter suggests to make 1,500 ships permanently churn up water high enough so that it could get to the clouds, whiten them, and increase their albedo effect (Wood 3). Roger Angel would shoot ceramic disk in orbit around Earth in order to create a global sunshade (Wood 3).

Over the years, Geosyntec Consultants which is in Florida, worked with clients who were operators of landfills and wanted to increase the life of a landfill. They wanted to use them at maximum capacity even if they were filled, covered and closed. One way to increase it’s capacity, is by doing vertical expansion along the landfill to add space for waste. Another way to get landfills to be used at their maximum capacity is by using them to do renewable energy park using two type of energy which are electric energy and heat or thermal energy.

Palm oil production is one of the reason for deforestation in the world. This is particularly true for Indonesia who is the world’s largest producer of Palm oil. The rainforests of the country are cut down at a hallucinating rate to be replaced by Palm oil plantations. The island of Sumatra is the part of Indonesia which has undergone the biggest deforestation in all of Indonesia, resulting in loss of animals and plants.

Seaweed is popular in asian cuisine, but it also sucks up carbon dioxide in the ocean. In fact, kelp in particular helps with carbon dioxode and also reduces the ocean acidification, which affects global warming in the ocean. Marine ecologists from the University of British Colombia states that if we expand seaweed farms, we could remove billions of metric tons of carbon dioxide from the atmosphere. Furthermore,  the researchers also demonstrated that a seaweed farm or forest can also shelter more than 800 species of marine life.

            In the article “Environment: GLOBAL WARMING KILLING OCEANS' LIFE CENTRES” written by Jim Lobe it explains how climate change is showing us no signs of backing away and not only does it raise the temperature in our atmosphere, but also it also raise it in our ocean water, which can cause human and overall the ecosystem a lot of trouble, specifically the coral reefs. Studies from the Global Coral Reef Monitoring Network show that more or less 70% of the world’s coral reefs are being affected by destructions.

Olive oil is the sort of ingredient almost everyone has in their kitchen. It is mainly produced in Mediterranean countries, which are responsible for 97% of the olive oil production, which generates 8 billion gallons of wastewater every year. However, its production leads to major wastewater affecting soil fertility, drinking water, and ecosystems located near the olive oil mills.

Since they began in the GMO business, Monsanto has caused a lot of collateral damage to the environment with their Genetically Modified crops. For example, their Monsanto Roundup Canola has made organic canola nonexistent in the prairies, according to Saskatchewan Organic Directorate, due do pollen drifting across fields, thereby contaminating the growth of organic canola and making it GMO as well. Their Roundup products have also, over the last thirty years, been shown to reduce the amphibian population as the main active ingredient in it. glyphosate, is very toxic.

The state of Utah, due to a bad geographic position, is often affected by air pollution. The cold air is trapped under warm water trapping a lot of pollution throughout Utah. In 2012, Utah Gov. named Gary Herbert created a group of concerned residents called the Utah Clean Air Partnership (UCAIR). The main purpose of the group is to question people on what they could do to improve the environment.

 The article “Acid Rain go Away” by Shannon Shea Brescher describes the effects of acid rain on the Adirondack region of New York. Despite popular belief, acid precipitation comes not only in the form of rain, but also in the form of snow, fog, hail, and various other precipitations. Acid precipitation is a byproduct of industrial activity, and is a combination of ammonia, sulfur dioxide and nitrogen which mixes with atmospheric moisture. As a result, the precipitation is acidic.

In the article “Environment and Health Impacts of Household Solid Waste Handling and Disposal Practices in Third World Cities: The Case of Accra Metropolitan Area, Ghana” written by Kwasi Owusu Boadi and Markku Kuitunen explains how improper handling of solid wastes can trigger multiple health and environmental issues. As a location the authors chose to examine the rural area of Ghana in Accra. In the capital of Ghana, the researchers went ahead and interviewed 960 women that were head of their household and held a survey from June to August 2003.

Reply to: Ocean Pollution

Hi Audrey,

I find your summary very interesting and your topic got me to do more research on the subject. In fact, did you know that there is more than just plastic that pollutes our oceans? Substances such as oil, plastic, industrial and agricultural waste and chemical particles can be found in our water. There are many factors that contributes to ocean pollution such as sewage, the release of toxic chemicals by industries, land runoff, large scale oil spills, ocean mining and of course littering. All these causes have specific consequences on the ocean and the organisms living in it. For example, the oil released in the ocean makes it difficult for marine life to move or fly properly or feed their children. On a long-term scale, the effect on marine life can include cancer, failure in the reproductive system, behavioral changes, and even death. Moreover, the cycle of coral reefs can be disrupted, the oxygen in the water is contaminated, some sea animals will not be able to reproduce, thus it will affect the food chain because of the extinction of certain species and finally it will affect human health. To conclude, I hope that the government of each country will put a system in place to save our ocean, thus our planet.

Hey David, the article you wrote on sustainable development was very interesting. The statistics and calculations you mentioned regarding net-zero homes are assuring for individuals who seek more affordable consumption of energy along with a minimal polluting effect. As you mentioned solar energy is a very practical renewable energy producer, although, photovoltaic energy is very expensive, still, in North America. Companies like Solarcity may charge upwards of $38,330 for an average 2000 square foot 2-story home and 72,7000 for a 1-story bungalow home according to Teslarati. Evidently, as you mentioned anyone who chooses to employ such practices in their home could save upwards of $1,200 to $2000 especially if you have an electric vehicle. To add, when you mentioned better health due to toxin and chemical free walls, there is great upside to such innovations as they have the ability to prevent certain types of diseases and health ailments. All in all, as you mentioned net-zero homes are ultra-efficient, generating clean energy which in some cases you could be compensated for when having had generated enough extra available energy. Though these practices should be implemented more often, General Contractors, those primarily involved with the construction and finance of homes tend to spend the least money possible on new homes, thus I believe this is the biggest issue.

This is an interesting and well-written article that outlines many points regarding the major issue of plastic pollution. You have done a great job of giving a solid overview of said issue. However, you state that people would rather buy a new water bottle than using a reusable one. Indeed, it is true that people still go around buying new bottles and throwing them away when empty, but there are also more and more people with reusable water bottle. Despite the “social norm of efficiency” it is important to note that this way of thinking is already changing. We can also note reusable bags for grocery stores that have made the use of plastic bags decline since costumers have to pay for plastic bags now.

I have also found an article by the American Chemical Society which states that most of plastic pollution in the ocean comes from rivers whose water eventually will fall in oceans. In fact, some scientists led a research and found out that 10 rivers around the world are responsible for 88% to 95% of the total amount of plastic in the oceans. The article states that it would be impossible to clean up all the oceans. However, starting by cleaning some of the major rivers who spill into the ocean it would be possible to reduce the amount of plastic or general waste in the ocean. Indeed, doing such would reduce by 45% the contribution of rivers to plastic waste in oceans.

Great subject! Black carbon is something that often goes unmentioned!
You mention that "many governments" are signing this act; it would be good to know that it is specifically the G8 and G77 nations signing the act, not simply various groups of governments. It allows the reader to know the specific group that is involved. If they don’t know who the G77 or G8 governments are, they would be able to look them up, or you could even mention some of them here! It is also to know what you mean exactly by "the last few years"; if instead you stated "since 2009", it gives more information towards the context of the article and is less ambiguous. Though you stated CO2 emission reduction was not enough, it is also important to mention why; it is not enough because the effect of reducing CO2 emissions is too slow. The article clearly states that "An appropriately comprehensive climate policy must also
address the variety of non-CO2 pollutants that cause warming
and aim to minimize warming trends in the near-term so
that we do not commit the climate system to irreversible and
potentially catastrophic changes long before CO2 emissions
can be stabilized and reduced", essentially saying that only dealing with CO2 is too slow, and that dealing with Black Carbon may help buy time due to its more rapid effects. It would also be good to mention some of the statistics that the author states, such as the fact that the CO2 emissions need to be reduced 50-80% in order to have a strong effect against climate change, or how the climate has warmed 1.40 F. It would even be good to mention some of the stats about the amount of Carbon that is being released into the air, whether daily or yearly, and how much it contributes to the warming effect (though you said 60%, the article actually states 25-60%). Finally, it would be good to mention the solutions that the article gives for reducing black carbon such as applying filters on diesel fueled vehicles and how it will reduce the emissions by approximately 42% between the years of 2001 and 2020 in the US.
All in all, a good summary of the article!

Sustainable cities and societies are a must in order to ensure a bright future to the world's population. Many countries and government has decided to take action upon this subject, and decided to be leaders in the field of sustainability. Some countries as Iceland, are running on 100% renewable energy, they are also working on becoming a fully recycling-oriented community. Sweden is another leader into sustainability. They have cities as Växjö which is considered to be the greenest city in Europe. There is also the region on Malmö were they keep on working on creative innovative and creative way to achieve sustainability. They are using architectural concepts, and new efficient technologies as green roofs. Here is a great article about 7 examples of sustainability in Sweden that gives more detail about how they are doing: https://sweden.se/nature/7-examples-of-sustainability-in-sweden/ . Finally, the biggest leader in sustainability is Switzerland. The country has a rate of 95.5 in the Environmental performance. From a report posted by the country (https://www.myswitzerland.com/en-ca/sustainability-environment.html) has really high rate of recycling (94% of old glass and 81% of PET containers). Switzerland is also really protective of their environment with their high regulation on forest, and woodland; 14,8% of the actual country is used a national park to preserve the unique landscape. These examples of sustainable cities are really important because it proves that with the required investment and motivation, it is possible to create society to would sustain themselves. By having more kind of countries taking this kind of action, we would generate less toxic gases and reduce the world’s carbon and ecological footprint.

I think this post is interesting because I've briefly heard of net-zero homes but I didn't know that it was becoming something more open for the majority of the population. I was taking a look at your sources and I thought it was intriguing and that it would be interesting to mention that the American Association of Architects created a goal for 2030 to build more accessible and user-friendly homes for the population, however I feel like this construction is only really happening in Canada. I then went on to look at the house availabilities in the U.S. and saw that they cost twice as much - one home going for $749,000 - (and in some cases more) than the net-zero homes being built in Canada so perhaps that could be a big factor in their decreased production due to the fact that many Americans might not want to pay that much, especially when being coerced by politicians that global warming is not real.

I agree with you when you say that "Veganism is an easy way to live a healthier lifestyle, help the environment, all while saving the lives of many innocent animals".
In fact, according to an article I read written by the American Dietetic Association and Dietitians of Canada, having a vegetarian diets offers a high number of nutritional benefits, such as a lower levels of saturated fat, cholesterol, and animal protein as well as higher levels of carbohydrates, fibre, magnesium, potassium, folate, antioxidants such as vitamins C and E, and phytochemicals.
Furthermore, vegetarians have been reported to have lower body mass indices than non-vegetarians, which is healthier for you. Also, it has been proven that vegetarians have a lower rates of death from ischemic heart disease, lower blood cholesterol levels, lower blood pressure, and lower rates of hypertension, type 2 diabetes, and prostate and colon cancer. With all of these benefits, I do not see why people would not turn to vegetarianism. While a number of federally funded and institutional feeding programs can accommodate vegetarians, few have foods suitable for vegans at this time. It is now time to convert people to vegetarianism. In the article it is mentioned that dietetics professionals have a responsibility to support and encourage those who express an interest in consuming a vegetarian diet, which is perfect to spread vegetarianism among the population. They can play key roles in educating vegetarian clients about food sources of specific nutrients, food purchase and preparation, and any dietary modifications that may be necessary to meet individual needs. Menu planning for vegetarians can be simplified by use of a food guide that specifies food groups and serving sizes. There is no reason to not be vegetarian after reading all its benefits to the human body. And as your article mentions; it does not only benefits us but also helps the environment and saves the lives of many innocent animals. Let's think about it!

Hi Louis, I highly agree with your article summary that explains how hazardous waste have a threatening impact on human health and that countries should manage more properly their waste to avoid their impacts on living organisms. To add on your summary, a study made by Reza Najem and Lisa K. Voyce examined 112 households living near a thorium waste disposal proves that leaving nearby houzardous waste disposal can have a serious impact on human health. 55 households lived within three block of the thorium disposable and 57 others were living from 9 to 10 blocks away from it to compare their living. Each of the participants had to be living there for at least 5 years. They interviewed the people living in these households face-to-face or by telephone and noted each disease or conditions reported by participants. The results of Reza Najem and Liza K. Voyce’s study, is that even if the numbers that came out of this study were not high, the 55 households living nearby the thorium disposal had an increase of birth defects and liver diseases. This study adds on to your summary, Louis, and proves that hazardous wastes have a negative impact on the health of human. If wastes were better managed, and countries started thinking for green solutions, as you mentioned, for sure waste would have a reduced impact on human health.

I happen to stumble across your article and found it extremely interesting as it addresses a mainstream metropolitan’s serious issue, which is traffic. Traffics are expected to happen during rush hours only, but in reality it can happen at any given moment of the day or night. Since it is such a big problem that happens in our city, Montreal, it obviously affects our daily life and we should be searching for a solution. Many solutions have been brought up and supported by our city with posters encouraging a greener option of transport method and promotions such as 2 free of charge months on the accord of the yearly membership with the Opus card. With such approach to encourage its population to use public transport’s services, it leads us to believe that these approaches would lessen the congestion, but with some research done, I would have to agree with you that it is true that mass transit do not help lessen the weight of traffic present, even less by expanding lanes. The correlation between the increase of mass transit and the decrease of traffic has been proven ineffective by many studies where one of them is from the University of California-Davis.
However, the fact that the article claims that it shows no effect on the environment I strongly disagree with you. Since there is an overwhelming amount of studies where researches proves the effectiveness of public transports on our environment especially in comparison with single-occupant automobile. Studies where it claims that public transport uses 8.7% less energy per passenger mile than a typical automobile.
