E-waste

Around the world old electronics, or e-waste, is being thrown away and dumped onto normally pristine landscapes. Not only is this harmful towards the environment, but it harms the health of surrounding inhabitants as well. E-waste buildup over the years has been massive, and the complications it brings will only increase if something is not done.
This e-waste is greatly impacting the daily lives of the surrounding inhabitants. It harms the scavengers health, as well as polluting the area. Also, certain types of e-waste provides criminals opportunities to steal personal or sensitive government data. However, the exporters of the e-waste find that dumping the e-waste is cheaper than properly disposing of it.
The people that scavenge e-waste by literally cooking components are slowly poisoning themselves by breathing in toxins that are released. Personal or sensitive data can be viewed by hooking up hard drives from thrown computers and simply opening the files(Inquirer). The companies that export the e-waste state in the video that the exporters don’t want to pay to dispose of e-waste properly even though they realize its hurting the environment.    
To help reduce the amount of e-waste we produce, certain actions should be taken. For one, legitimately donating old electronics you don't want or need to friends or family will prevent that machine from contributing to the e-waste piles. Another way is to find a website or business that legitimately recycles your device, instead of exporting it out of the country. Also, you could consider selling your computer used.(3 solutions)
        I believe that e-waste is harmful to both people and the environment it pollutes, as well as providing opportunities for criminal activity. Selling old electronics or donating them instead of "recycling" them is the best way to avoid contributing to e-waste and I will remember to go for one of those paths with my old electronics. I'll just have to remember to smash my hard drive.

First

My name is Marcus Sellner and my major is nursing. I've spent much time around computers, yet managed to not learn much about them. Restarting the computer fixes most of the problems that you get. Updating your drivers assists performance greatly, and as a last resort, wiping your hard drive is sometimes necessary to continue using the computer. I'd like to learn the basic structure of computers so I can eventually build a computer. Learning how to build robots is also an interest. Upgrading my computers security would be wonderful.


We talked about how computers use preset programming to function and do as we wish. We input data though things like keyboards and touchscreens, and computers give us the information sought though monitors, speakers, and similar devices. Wireless networks, as such created though modems, are considered one unit, even though there are multiple devices.
