Lightbulbs have changed quite a bit lately. Compact fluorescent lamps were introduced as highly efficient alternatives to traditional bulbs before 100, 75, 60 and 40-watt incandescent lightbulbs are phased out of production by 2014.
The good news is that the bulb is so efficient that if every 60-watt incandescent in the country were replaced, $3.9 billion and 20 million metric tons of carbon emissions would be saved in one year.
Sustainable fashion has been in vogue and on the radar since the early 1990s, but it’s only gone mainstream recently.
Synthetic fibers like polyester produce significantly more carbon emissions than organic cotton, and quite a few large brands were found to use some harsh chemicals to dye and manufacture their garments.
Either way, ethical and ecological clothing is catching on. H&M is the biggest user of organic cotton in the world, and brands like Nike and Zara have followed suit.
Single-use plastic bags have been outlawed in a few major cities across the country like Seattleand San Francisco, and others like Washington D.C. have instituted a per-bag tax. China imposed a nationwide ban in 2008.
But people should be wary and keep grocery bags clean – a 2012 study found a connection between reusable bags and a spike in E. coli infections.
