Dealing With E-waste (2)

Possible e-waste solutions
Owners can prolong the life of their gadgets by upgrading less frequently and by repairing the devices instead of replacing them. Owners might also choose to sell their old gadgets to a company like Gazelle that prepares them for resale overseas. That way, owners can earn money while preventing these devices from ending  up in a garbage dump. Similarly, owners could send their used electronics to Atteor, a company that specializes in extracting the valuable metals in used gadgets.

Some waste-management experts are promoting green chemistry. Green chemistry attempts to stop e-waste by designing safer chemicals to replace the hazardous ones currently used in making electronic products.

And green chemistry aims to design products that degrade easily, as opposed to plastic ones that take hundreds of years to break down.

Another creative solution to the e-waste problem has been found in Togo, West Africa, where members of WoeLab built a 3-D printer from scraps of e-waste. And in Ghana, a company called FairPhone is making phones using recycled materials. While such creative efforts won't completely solve the e-waste problem, they do offer a ray of hope.

Teaching Topic: Language Purists and Realists (語言的純粹主義者與現實主義者)
美國的小學老師, 最愛糾正小朋友的一件事,
就是當小朋友問:
Can I go to the bathroom?
老師會反問:
I don't know. Can you?
因為嚴格的來說, 小朋友應該說:
May I go to the bathroom?

英文文法來說:
Can I ....是指我有沒有這個能力,
但一般人不會在乎正確的用法,
因為事實是語言不斷的在改變演化,
語言的 purist 力求文法語言的正確使用,
但是 realist 現實主義者, 注重可以溝通可以使用即可
