In my opinion, the most dominant problem facing by the engineers today is finding the solutions for grand challenges. According to the article "Introduction to the Grand Challenges for Engineering"(National Academy of Engineering, 2008), the world's cadre of engineers are finding ways to put knowledge into practice to overcome these grand challenges. We are unable to neglect or deny the importance on interactions between environment and living beings.Human beings are strongly depend on environment such as the energy sources, food production and others. The Earth's energy-source will be used up one day. Engineers need to develop new sources of energy. For example, using solar energy instead of the ongoing use of fossil fuels. Solar energy will not cause pollution and it can be used as a long-term energy. Since 20th century, solar energy had been used in our life. Now, engineers are trying their best to make it economical and efficiency. Besides, burning of fossil fuels will cause global warming. It will produce carbon dioxide, a key gas involved in global warming. "Global observations coordinated by WMO show that levels of carbon dioxide, the most abundant greenhouse gas in the atmosphere, continue to increase steadily and show no signs of leveling off,'' Secretary-General Michel Jarraud said (Greenhouse Gas Hits Record High). Now, engineers are developing a new method to capture the carbon dioxide. However, there are still many barriers await engineering solution. Let us wait for the engineers to change our life and make a better future.
