Description: There’re two people in the image that trying to recycle a big pile of shoes by collecting them and selling them to the industries who would like to source the materials of shoes and then process them into raw materials that they then sell.

Assessment from me: I think it’s pretty effective a way to reduce our waste shoes. We just did a project called “precycling” for the last few weeks, and I learned that it’s necessary to recycle clothes and everything else that’s recyclable after using them for once because the landfill is too few for us to put all our garbages there.
Comparing with Canada where export most of the recyclable waste to other countries, people in Bangladesh should feel lucky to have some industries who want to recycle the produces for them.

Description: People are building with “low CO2 bricks” in Peru. It’s a method to reduce the emissions of CO2 by using electrically powered ventilation. They store bricks for some days before loading them into the kiln.

Assessment: I don’t think it would help to reduce the emissions of CO2 a lot because it’s not a very scientific method that’s been proved by experts. They seem to use physical method only so it’s not very persuasive to me.

Today’s weather:

We predict that the weather tomorrow would be sunny since there’s a high pressure coming to us; there’s also a cold front coming from a farther area with a slow speed toward us so we don’t think it would affect the weather a lot.

We predict that we are going to have a sunny day since the low pressure is going to be gone and a high pressure seems coming to us. We might continue to get haze since the smoke of the forest fire is coming to us.

For the predictions, we concluded that if the cold front was coming to us, and it seems like it is moving toward us, we could expect some precipitations and grey sky and rainy weather. Because of the pressure changed from L to H, we should probably get sunny sky.

We predict that at the end of the week we are going to have a cloudy sky because of the cold front which is coming soon.

Today is May 24th, 2019

Weather prediction: we saw that we were going to have a high pressure tomorrow, so the sky will get clear in a few days. It might also be more windy because the isobars are staying close together.

BC’s waste management syetem is not as efficient as we thought it was, there’re still improvement we need to make in order to make the system more sustainable. Let’s first take a look of how some other parts of the world deal with their garbages:

As the world’s largest trash generator, China is still finding a way to deal with its own garbage while a big amount of garbage ending up becoming landfills and flowing down the river. This is a drawback of China about how to deal with the waste, however, it has the world’s largest e-commerce market, consisting of 42% of global transactions, and the largest mobile payment market, These two pole positions make China the best place in the world to innovate digital solutions for waste. Therefore, a lot of developed countries send their digital waste China, this can also be a solution to BC’s digital waste.

Also, some Chinese restaurants are using a U.K. technology system called Winnow”, to save the food waste from the kitchen chefs, how it works is that the kitchen staff are trained to log the food they are throwing away, which is then automatically weighed by the trash bin. The technology analyzes the value of what is dumped, in both economic and environmental terms, and provides analytics reports to help the kitchen run more efficiently. Globally, Winnow’s system has helped to save one meal from the bin every two seconds, since starting in 2013. it can probably be an efficient solution for BC’s food waste.

Rather than using other kinds of plastic, Japanese people use a plastic called “PET” resin, which is a reusable material, instead. What Japan does with its domestic PET resin waste is that they crush the collections into flakes then pelletize them so that they can get fiber out of those resin wastes to create spun yarns. A lot of recycled uniforms are made through this process and it reduces the plastic wastes efficiently. So why don’t we use this kind of plastic and try to recreate uniforms and clothes out of them? If companies in BC utilizes the technology of recycling this type of plastic, we don’t even need to send our own plastic waste to other developing countries, where all the plastic waste ended up piling up somewhere unknown.

Generally speaking, Canada doesn’t seem to have a complete circular economy system; when it comes to deal with various types of wastes, the most common thing Canadian government chooses to do is to transfer them to some other countries instead of fully reuse and recycle the recycable waste. Since the biggest reason why the companies in BC would not like to create more useful things from recycling our wastes is the few benifits they could get from doing so, the government should introduce policies to encourage more companies to regenerate our waste effectively except for landfilling and reducing the amount of useing the unrecycle wastes; and at the same time, companies that are in cahrge of dealing with wastes in BC should learn more efficient technologies to recycle and manage our wastes from other countries that have more advaced technologies.

I think it’s better to combine the practices like clearcutting with reserves, clearcutting, and selective logging together in order to continue BC’s forestry industry and also keep the sustainability of the silviculture system of BC at the same time.

Although that clearcutting is the most efficient and least expensive way of harvesting wood, it may create difficulties that impede the establishment of regeneration. The statistic showed that in 2015-2016, harvesting on public lands was by clearcutting with reserves occupied 85% of BC’s forests, clearcutting occupied 11%, and retention cutting occupied 3%; which is good to the forest conservation since the companies did reserve the area where they cut trees down. “The average size of clear-cuts has decreased, improving the balance of environmental and economic objectives.” quoted from Wikipedia. From the picture, we can see that clearcutting with reserves is more renewable a forestry practice than the only clearcutting.

Selective logging is a practice of removing one or two trees and leaving the rest intact. It is often considered a sustainable alternative to clear-cutting, in which a large swath of forest is cut down, leaving little behind except wood debris and a denuded landscape. In my opinion, selective logging seems to be the perfect way to maintain the sustainability of BC’s forestry. Because sometimes the forest fire is caused due to the trees are too closely growing near to each other, and the selective logging reduces the possibility of trees burning themselves efficiently.

A silviculture system is a sum of activities that including how trees are harvested, regenerated, and managed over time. Foresters choose a silvicultural system according to the ecological traits of the tree species, and by balancing the purposes of the landowners. The graph below tells us that it’s not a simple step to keep the silvicultural system work, we need to combine the clearcutting, particle cutting which is similar to selective cutting, and also clearcutting with reserves.

As we all know, a big part of BC’s economy depends on the forestry, and a big amount of people are working for the forestry industry.

From the chart above, we can see that the total amount of employment in BC forestry presented an increasing trend during the recent 3 years. And we also talked a lot about it in class that the forestry of BC is an important part of the economy. So the best way to develop the forestry and also to reduce the areas experiencing the deforestation is by combining different forestry practices together and that way we can reach a balance of the silviculture system in BC.
