The Damage of E-waste
Electronic waste, or e-waste, has become anissue of serious concern to the public as a growingnumber of electronic items are discarded in landfillsevery year. Many consumers are not aware that electronics like computers and cell phonesactually contain toxins that can leach out into the soil and damage the environment.
E-waste compounds pose hazards to the environment as well as the human beings. Tostart with, when exposed to heat, the components of e-waste release toxic fumes and gas,polluting the air and causing global environmental problems. When circuit breakersdeteriorate, they release toxins, such as mercury, that pollute groundwater. In addition toits damaging effect on the environment, researchers have now linked e-waste to adverseeffects on human health.
In my view, it’s high time that the damage of e-wasted should be realized by the public andmeasures should be taken to cope with this issue. One idea is to put greater responsibility onthe companies that produce the goods. It should be mandatory for them to taking theabandoned items back and dispose them in an environmentally-friendly manner.

Some people can now no longer imagine life without their cell phones. The fact that theyare so popular proves that they are useful and convenient. Cell phones enable people toeasily and quickly communicate with one another; wherever you are, you can instantly reachsomebody. Cell phones eliminate the trouble of not being able to meet someone in person,and therefore increase business's efficiency.
Mobile phones necessarily also harbor disadvantages. The radiation such phones emit ishazardous to one's health. Furthermore, if people become too reliant on the use of cell phones,our face to face skills may decline. Any new invention has its drawbacks, and such negativeaspects cannot always diminish its popularity. Despite the negative effects of television, forexample, the number of people who own televisions continues to grow at a tremendous rate.This is also the case with mobile phones. People won't stop eating just because of the riskofchoking. In addition, the swift development of science and technology will likely eliminatethe hazards cell phones may cause. One can safely predict, therefore, that with theintroduction of new techniques, mobile phones will have more applications and become evenmore appealing to customers.
