When it comes to designing the first question that should be asked is:- what solution is one making effort to provide to cater for the intending design?, for great architecture is beyond just buildings; it is more about creating a sustainable destinations that make people feel healthy to live in, motivated to work in and always wanting to come.  A sustainable city should provide the highest quality of life and also ensuring that the needs of future generations are not compromised. Although several conditions influences the quality of life, such as high crime rates, general health, unemployment, income growth, and most of all, cost of living. The built environment, and the designed pattern of the city has a great influence on the general quality of life of the city as well as helping to minimise people’s impact on the environment. It is very important to note that for a sustainable city to be achieved there must be a collaborative process between municipal authorities, urban planners, developers, architects, landscape architects, engineers, and energy, water companies and all other Environmental and Developmental bodies. All this holistically create a master plan approach that will result into a vibrant, healthy and Sustainable balanced environment. Everyone should also be made to effectively participate in the process, if possible education model should also be created for the city residents to follow and by so doing the future needs and possible solution is met in the now. It is very obvious that there will be a significant increase in population and urbanisation, which will in turn have a tremendous impact on the city structure, infrastructures and resources, as well as the health and wellbeing of its inhabitants. Necessary solution must be provide to cater for the high standard of quality living. In achieving this the people should be carry along and made to understand properly the essence of sustainability, this sense of belonging will make them passionate about improving their own city and in the long run result into a positive way of thinking about sustainable cities. For a perfect sustainable city to be achieved the urban transportation must be put into consideration. There are many challenges in the way we move about inside our cities. Congestion, safety, air pollution, noise emissions and high levels of CO2 are some of the key challenges we face today in growing cities. That is why in most big cities in the world right now encourage the use of bicycles for mobility to tackle congestion and CO2 challenges. Walking and cycling are otherwise called “Active transport”, are more than just a healthy mode of transport. From Research it has be established that active transport brings many positive social, environmental and economic benefits to the cities involved. All these gives us a positive perception about the Solutions involved in Sustainability.

Critical thinking s the ability to engage in reflective and independent thinking. Critical thinking might be described as the ability to engage in reflective and independent thinking.

In essence, critical thinking needs you to use your ability to reason. It is about being an active learner rather than a passive recipient of information. Critical thinkers constantly question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments and findings represent the entire picture and are open to finding that they do not. Critical thinkers will have to identify, analyse and solve problems systematically rather than by intuition or instinct. Someone with critical thinking skills can: Understand the links between ideas. Determine the importance and relevance of arguments and ideas. Recognise, build and appraise arguments. Identify inconsistencies and errors in reasoning. Approach problems in a consistent and systematic way. Reflect on the justification of their own assumptions, beliefs and values. Critical thinking is thinking about things in certain ways so as to arrive at the best possible solution in the circumstances that the thinker is aware of. In more everyday language, it is a way of thinking about whatever is presently occupying your mind so that you come to the best possible conclusion Don’t ask what the world needs. Ask what makes you come alive and then go do that. Because what the world needs is people who have come alive.” Howard Thurman Critical thinking is . In our constant changing, high-pressured, distracting world, our working memory gets stressed beyond the breaking limits Our brain's capacity is constantly over burdened and tend to diminish in function over time. Deep thinking needs effort and patience to be properly activated On the other hand, effort must be exercised to achieve the fine art of thinking deeply. You also need effort to maintain focus on one particular train of thought. Always set aside some few minutes in a day to focus on improving how you think, and in do doing enriching the depth of your every day knowledge. “I constantly see people rise in life who are not the smartest, sometimes not even the most diligent, but they are learning machines. They go to bed every night a little wiser than they were when they got up'' ....Charlie Muroe Keep looking for answers. If something doesn’t make sense to you, ensure you look for ways to broadens your knowledge so as to understand it. If you desire to be a deep thinker, you have to cultivate the habit of asking deep questions. You asking should not have boundaries. Always ask why repeatedly! Consciously force yourself to use your brain more. The more often you embark on a new skill, study a new subject, or dig deeper into any topic, the stronger your mind becomes. Pick up one new thing every week, continue working on it as you learn new things. The more you exercise and challenge your mind, the deeper your understanding becomes. Your career, personal life and your destiny will never be the same if you can go the extra mile to understanding topics, issues, and subjects clearly.
