Do you knows what technology is? Technology is a scientific method to achieve practical goals. Actually, technology has existed since ancient times. The development of technology has grown dramatically and continues to evolve today. Besides having a positive effect, technology also has a negative effect on us and the environment in our daily life. For example, plastic waste that can’t be broken down by the soil, motor cycles and vehicles produce air pollution and air conditioners contained CFC, which causes depletion of the ozone layer. On the other hand it doesn’t mean that we mustn’t use technology; there are some ways to reduce the negative impacts of technology. Plastic is a very useful thing in life. A plastic can be converted into a lot of things such as rulers, bottles, and plastic bags. But a lot of people who don’t care about the plastic waste, such as mothers who carry groceries with plastic bags and, after arriving home, discard the plastic bags. Another example is when we immediately throw the plastic bottles away after drinking. It causes the plastic garbage to pile up and it can not be broken down by the bacteria in the soil. To avoid this negative effect, we can change the plastic bags with go-green bags or use a glass bottle. Another way is to produce household plastic ware such as pencil cases and bags. Motorcycles and vehicles have many functions for us. For examples, we can save travel time to a place and if using a car we can still go even if it was raining. But there are no motorcycles and vehicle exhaust emissions that do not cause air pollution that results in bad air quality and global warming if we continue to use motor cycles and vehicles constantly. We can reduce the air pollution in some ways. Don’t ride them if it’s not necessary. Why don’t we ride bicycles? There are no negative effects using bicycles, because bicycles are a simple technology without machine. Using bicycles also has benefits
