the most important to the profession

Nowadays, engineers play a more essential role in our world, and we can find engineers everywhere. In a sentence, the world cannot leave engineers any longer.
We can say that engineers are the builders of our civilization. Engineers have already created many miracles, such as the Great Wall, the Great Pyramid and many other incredible things. Engineers were considered as the designer and builder of architecture traditionally. However, in today’s world, the task of engineering is more than building. Engineers are involved in many other fields. No matter how fast the science develops, we need engineers to apply it. For example, as the population grows fast, engineers need to use the genetic technology to increase the food product, so that nobody will suffer in hunger, and also as the fossil fuel consumed rapidly, engineers need to find some new source of energy to replace the fossil fuel.
Therefore, a large demand of engineers will be required. This is the most important fact to the profession. Graduates with engineering education will have more job opportunities in the future. Most of them are employed even before they graduate. This is a precious opportunity for engineers. Meanwhile, it is also a great challenge for engineers. Many specific grand challenges await engineering solutions. They need to make more contribution on sustainability, health, vulnerability and joy of living. The stage of engineering can be depicted as a wide, which needs many engineers to performance on it together.
In addition, the modern world needs engineers, and this provide many challenges to engineers. Engineers should take this opportunity to make our future more beautiful.
