Green Roof 

As the recreational land use is not enough in the inner city, most of the building try to promote the roof top garden to provide more leisure space for the building user. They will try to use the roof top for the gardening use and leisure farming use. It can create one more place for the people to rest and enjoy the green cover.

The other benefit for building the green roof to reduce the sunlight to hits the top of the building. It can reduce the temperature of the building because of the less cement cover area. Therefore, the energy can be saved for the cooling facilities.

Although the green roof have some advantage, there are also some barriers to promote it to public. First is the maintenance cost is high, the second is the loading of the building may not support it.

Underwater Oceanscrapper


The above two photo is the city called“Aequorea” ,which was created by Belgian architect Vincent Callebaut. This is the concept that the city is built under the sea and estimate can stay 20,000 to stay in this under water city. The concept of this city is to support the food and energy itself. This building is include the office, farm land and laboratory etc. The concept of this is to save the energy usage in the earth and  try to lower the carbon footprint.

This concept of this city is wonderful. The city can supply their own needs and the energy. The city can solve the city's lack of land supply problem and over population. Due to the global warming cause the sea level increase,  the percentage of the continental become less. Develop the under water or above the sea development will become the next trend of the property development.

Ocean Pollution

The pollution in ocean become the most serious problem nowadays, Many people dump the garbage to the ocean. Those garbage, especially the plastic, give the huge damage to the sea life. For example the sea bird and the sea turtle.

(Dead Sea Birds body fill of Plastic Garbage)

The above photo is shown that the dead sea bird body if full of plastic garbage. The reason is that they can not recognize the small things, After the reflection of the sunlight, the plastic garbage become sensitive for the bird. When these plastic were ate by the bird , it can not be digestion and remain in the birds stomachs till they die.

Another victim is sea turtle. The plastic bag is look like their main food - Jelly fish. It is toxic for the sea turtle and it will remain in their body. Another situation is the plastic will trap them and affect their growth. For portect the sea life , we shouldn't pollute the ocean and don't put the rubbish into the sea. Another way to help to protect our environment is get involve to the  beach cleaning activities. It can raise awareness about protecting the ocean.
