Greenery on the Roof:

“Greenery on the Roof”, Climate Visuals, 2019. Available: https://www.climatevisuals.org/images?f%5B0%5D=theme%3ASolutions&id=1192. [Accessed: 02- Jun- 2019]

The image shows people are seeding on the roof on the government building in Mexico City.

How it work:

It can reduce the energy consumption. A green roof can protect the building from sun heat. Also, during rainstorms, it can store 75% of water to grow plants, and rest of the water will return back to the atmosphere. This system is also ability to sequester carbon

The green roof can even reduce the average temperature in a city.

Dog, Family and Turbine:

The image shows a dog and a family in front of a wind turbine.

How it work:

The wind turbine is alternate energy, which is change kinetic energy into electrical energy.

The large turbine can be used to provide energy for family use. There are two types of turbine, vertical and horizontal axis. Now, the blade length is increase, make it becomes more efficient.

In Malaysia, a lot of sort of materials can be landfilling. They have Public Cleansing Corporation, incinerators, anaerobic digester, and composting plants. In BC, people have already improved the sustainability of waste management, a lot of materials and energies can be recycled or protected, but per capita volume of waste is still increasing. Because it is inevitable to produce garbage, so BC’s waste management system can advance new technologies which can reduce waste or develop new recourse. Also, people may create some new materials which can be reduced, reused, and recycled easily.

I think Pacific salmon is not sustainable. From the video, I learned about the wild salmon’s unusual decline.


Pacific salmon is a very important resource in the world, it is important to economics, ecosystems. However, the population of wild salmon begins to decline in early 1990. People need to find out the problems.  They have concerned about overfishing and pollution. Finally, they find a kind of bacteria, which was released form 2007, over 10 million have vanished. They do labs to test why the fishes might disappear. DFO find out a kind of disease called Isavirus, this deadly string was caused by imported salmon eggs from Europe, around 70 percent are out of string and trade back to Norway. This flue is an international reportable disease, which means it can go anywhere and caused 2000 dollars of damage. However, the government did not want to take it seriously, so they think there is no ISA.


The test by 4 different labs, tree of them shows the positive sample of ISA. This is a big problem form BC because it is not only a culture but also a way of life.

The Ethic of care toward the environment is the moral relationship or moral status. This moral obligation can be created by raising awareness. We believed about something are morally wrong, for example, when people destroy parts of the natural environment or waste natural resources, we believe that this is wrong. We would following the rules in the environment and society. When people have an environmental ethic is usually because they can benefit from the environment, for example, the human can use plants to make medicine, get nutrients, foods； they are daily necessities, so people have the awareness to protect the environment. For some people who do not adopt this ethic of care; they can learn from documentaries to know how important it is. I think we should adapt to an ethic of care towards the environment.
