How would you predict and minimize potential risks or abuse of your work?

Engineers try their best to design and make products to improve the quality of life, but at the meantime, some products also bring some disvantages to human beings. For example, plastic bags used to be ragarded as the most important inventory in 20th century, while now they cause serious pollution problem. We can see that it is also necessary for enginneers to preidct and minimize potential risks of their work.. however, it is not that easy since risks always come out accidently.

To predict potential risks of enginneering products, we need to fully undestand the products from different aspects. There are a few questions engineers should consider before they put their products into the market, such as how to use the product, what can be done with the product, and what may be dangerous when using the product. An overall understannding is important to reduce the risks of the products, not only how to make such a product.

After recognising the potential risks or abuse, minimizing them becomes easier. Sometimes minimizing the risks and abuse of the products means also minimizing the using efficiency of the products, which may make the produsts less useful. Certainly, enginneers and bussinessmen should consider the safety first instead of the economic benefits.

One of the problem I met when writing my engineering essay is how to write more academicly. To write more academicly, there are two important factors, vocabulary and organization.

Vocabulary is the basic unit of an essay. The choice of word is the key to determine the accuracy of the meaning. Bad choice of vocabulary leads to misunderstanding, while good word choosing improves the expressing of the essay. As we know, academic essay needs high accuracy of meaning expressing. Little difference of words may make a large distance of meaning when writing academic essays.

Organization is another important factor which helps in writing in academic essay. Different kinds of essay requires different block or essay organization styles. For example, argumentative essay follows the order of organization: introduction, body paragraph with rebuttal to opponents’ views, and summary or conclusion. Good styles of organization make a shortcut to guide readers to know what the author want to say and help the readers to understand better.

To write an accurate and well-organised article, I need to pay more attention to my word using and paragraph structure. Certainly, practise makes perfect. I have to write more to gain exeperience.
