There’s BPA in cash register receipts?

Feb. 12   Leave a Comment  

Laboratory tests found high levels of BPA on 40 percent of thermal paper receipts sampled from major U.S. businesses and services, including McDonald’s, Chevron, CVS, KFC, Whole Foods, WalMart, Safeway and the U.S. Postal Service, among others. BPA in paper receipts also contaminates paper recycling and is showing up in napkins, toilet paper and other common papers with recycled content. (Thinkstock)

Water usage in the bathroom

Jan. 24   1 Comment  

Some 60 percent of our household indoor water usage happens in the bathroom. Toilets are the biggest water hogs, with older models using as much as eight gallons per flush. A shower, even with a low-flow shower head, can use up to 40 gallons of water, and a bath can use up to 50-60 gallons. (Thinkstock)

Analysis: Cutting down forests for biomass fuel

Jan. 24   Leave a Comment  

In theory, burning any kind of plant material for energy is a carbon-neutral endeavor, but chopping down forests for ethanol is unwise because they cannot be regrown quickly. And tree plantations don't provide the clean water, storm buffers, wildlife habitat and other ecosystem services that natural forests do. Pictured: A wood biomass plant. (Thinkstock)

The environmental impact of gold mining with cyanide

Oct. 30, 2011   Leave a Comment  

Some 90 percent of gold mines around the world employ "cyanidation," the use of a sodium cyanide compound to separate the gold from finely ground rock. At a gold mine in Romania in 2000, the accidental release of 100,000 cubic meters of cyanide-rich waste into the local watershed killed all aquatic life in nearby waters and cut off water supplies for 2.5 million people.

Will the U.S. ever put limits on greenhouse gas emissions?

Oct. 15, 2011   Leave a Comment  

Politics still stand in the way of efforts to limit U.S. greenhouse gas emissions. Two efforts, the American Clean Energy and Security Act (ACES) of 2009 and the American Power Act of 2010, got tabled or failed to make it to the Senate floor for a vote. ACES was, however, passed by a narrow margin in the House of Representatives, the first time the legislative branch has called for sweeping climate legislation.

What is nonpoint source pollution?

Aug. 26, 2011   Leave a Comment  

Nonpoint source pollution comes from many diffuse sources, but in the aggregate creates a formidable challenge for municipal, state and federal environmental and water control authorities -- and is likely the largest threat to our water quality.

Does medical waste still wash up on American beaches?

Aug. 26, 2011   Leave a Comment  

Medical waste washing up on New Jersey beaches was a big problem in the late 1980s, closing beaches along a 50-mile stretch of the New Jersey shore. Although that problem was addressed for the most part, bacterial contamination from sewage treatment outflows, contaminated storm water and other sources caused more than 24,000 beach closures or advisories across the U.S. last year.

KFC, Taco Bell, and the destruction of the rain forests

YUM! Brands, which operates 38,000 fast food restaurants in 110 countries (including KFC, Pizza Hut, Taco Bell, WingStreet, A&W and Long John Silver’s), continues to ignore calls to stop sourcing palm oil, paper and other goods from suppliers notorious for destroying tropical rainforests in Indonesia and elsewhere. Indonesia’s tropical rainforests are home to orangutans, tigers, elephants, clouded leopards and dozens of other endangered plants and animals. (Media credit/Marufish via Flickr)

Re-processing nuclear waste

July 9, 2011   1 Comment  

Reprocessing nuclear waste -- practiced in France and several other countries but not in the U.S. where it was invented -- involves breaking down spent nuclear fuel to recover material for use in new fuels. Proponents say it reduces the amount of nuclear waste, resulting in less highly radioactive material that needs to be stored safely. Pictured: France's Cattenom nuclear power station.

Would legalizing pot be good for the environment?

May 14, 2011   Leave a Comment  

Legalizing pot (left-hand image), some say, would eliminate many negative environmental impacts associated with clandestine growing and illegal smuggling. It would also likely open the door for the legalization of hemp (right-hand image), a relative of the cannabis plant that can't get you high but could help us sustainably meet a good amount of our fiber and fuel needs.
