Yes, it’s possible. Gary Chang, an architect living in Hong Kong, managed to transform his 344-sq-ft apartment into a really amazing living space. He named it the ‘Domestic Transformer’.

As we all know, Hong Kong is very densely populated and land is particularly expensive. The people have to learn to live and fully utilise the limited space they have.
Sometimes, I wonder, is it because our earth is blessed with so many resources, that we have been taking them for granted? As Gary Chang can maximise the functions of such a limited space, hopefully someday our knowledge in science and technology has improved to the extent whereby we could achieve the maximum result using minimal resources, increasing the efficiency and reducing usage and waste of resources.

Besides that, one doesn’t have to be dubbed an Environmentalist to address green issues. Some people have the tendency to think that it’s an environmentalist’s job to find solutions, when in fact people from all fields play a part. As people of different expertise or different disciplines play different roles in society, it’s important for all of us to work on combating environmental issues together, in our respective ways.
