Cutting a Course of Pollution

CRUISE SHIPS introduce millions of people to exotic places throughout the Americas. As the industry grows, so does the size of the ships. Some carry as many as 5,000 passengers and crew. According to a study conducted by analyst G.P. Wild, the number of people taking cruises will reach 20.7 million by 2010. The Caribbean is the principal destination accounting for almost half of all cruise traffic.

The problem — according to Oceana, a non-profit organization based in Washington D.C. — is that cruise ships are legally able to dump raw sewage into the ocean. To address this issue, Oceana has launched the Stop Cruise Ship Pollution campaign with two goals in mind: create federal legislation in the U.S. to control cruise ship water pollution and convince cruise ship companies to install modern sewage treatment equipment. “These boats go to some of the most beautiful places on the planet, places that are already struggling with all kinds of pollution from development,” says Oceana Pollution Program Director and Senior Scientist Jackie Savitz. “These boats are capitalizing on the glory of the marine environment and in the meantime they are dumping all kinds of waste.”

Each day an average-sized cruise ship hosting 3,000 passengers and crew generates 30,000 gallons of sewage. An additional 255,000 gallons of waste water comes from sinks, dishwashers, and laundry — much of which contains toxic chemicals from industrial cleaning products, dry cleaning, and photo processing. Under current environmental laws, all of this waste can be dumped untreated into the ocean once the ship is more than three miles away from shore. “Harmful nutrients in sewage like nitrogen and phosphorous are well known pollutants that cause low oxygen problems like the dead zone in the Gulf of Mexico,” explains Savitz. She says that raw sewage contaminates marine ecosystems and contains viruses that can make humans and marine life sick.

The cruise ships have responded to public pressure by voluntarily adopting memorandums of understanding and waste management policies that agree to fully comply with laws and regulations, welcome new technology, and minimize waste. “We make our living off of pristine environments and we have no reason not to be invested in the future of the environment,” explains International Council of Cruise Lines President Michael Crye. He says that the industry has invested millions of dollars in advanced waste water treatment on board cruise ships and that some of the new systems — like those in use in Alaska —  discharge water that is drinking-water quality. “Our mandatory waste management practices and procedures basically mandate that none of our members discharge anything within four miles of the shore unless they have these advanced wastewater treatment systems installed,” he explains.

Oceana wants all cruise ships to install the most current waste treatment technology and estimates that cruise ships could install new technology within five years at a cost of only $1.50 dollars per day per passenger. In order to find out if cruise customers would support  the cost of new technology, Oceana hired Greenberg Quinlan Rosner Research, Inc. to conduct a survey of cruise ship patrons. The poll revealed that six out of ten cruisers are willing to pay extra to make sure that cruise ships never dump sewage into the ocean. More than 90 percent of this group said that they would pay more than $25. “What we want them to do is get into the 21st century and upgrade to state-of-the-art sewage treatment and then we’ll be off their back,” Savitz says. “If they treat the stuff and stop dumping raw sewage, we think the customers will be a lot happier and the oceans will be a lot better off.”

Purses from Plastic

| ChrisHardmanWriter

THE UBIQUITOUS PLASTIC grocery bag—used for lunches, garbage cans, and groceries—is one of the most prolific sources of pollution in modern-day society. Scientists estimate that worldwide people use 500 trillion plastic bags each year. In the Americas alone, the United States reports using 380 billion plastic bags a year. Cheap to buy and easy to store, the plastic bag has become the favorite of grocery stores who no longer ask, “Paper or plastic?”

Lack of recycling programs and improper disposal of the bags create a waste nightmare and environmental hazards that are too complex to track. Non biodegradable plastic bags travel on the wind polluting our oceans and forests or take up permanent residence in our already overcrowded landfills.

Since 2006 an innovative program that started in Costa Rica is using those bags in a most environmentally friendly way. Women living in small villages on the Caribbean Coast convert the plastic bags into thread and weave attractive and colorful purses with them.

Weaving for Nature is run by WIDECAST, a conservation organization that protects sea turtles in the Caribbean and its surroundings. The program solves several problems at once. The bags are re-used, eliminating the need for disposal, and the business gives people an environmentally friendly income source.

The program is organized to promote fair trade standards with an environmental mission. The weaver receives 75% of the profit and the rest goes toward sea turtle conservation efforts. The weavers, mostly housewives in small villages, work under fair and relaxed conditions and are compensated for all stages of production from collecting and washing the bags through the finished product.

According to Didiher Chacon-Chaverri, WIDECAST Country Coordinator in Costa Rica, weavers produce about 3 purses a week that means they can earn $180 a month to supplement their family’s main income.

To date the project has employed more than 50 women in villages on the coast of Costa Rica, Panama and Nicaragua. In 2008 the sale of bags, coin purses, plastic figures and Christmas Tree ornaments generated $75,000 in income for the four coastal communities.

The environmental benefits of this program are far-reaching. Along the Caribbean coast of Costa Rica and other countries, the plastic bag is a deadly enemy of marine habitats.

Because many of these bags are thrown on the ground or tossed into rivers, they often end up in the sea where they suffocate coral and kill sea turtles. For the hapless sea turtle gliding through the ocean, a plastic bag looks just like its favorite food, the jellyfish. The turtle gobbles up the bag and either chokes on the plastic or feels full and stops looking for real food.

Unfortunately plastic waste of any kind affects the entire marine environment. Because plastic bags are made of polyethylene, they are not biodegradable, and even if the bags are broken into smaller pieces, their tiny particles invade all levels of the food chain causing disease and sometimes death for marine life.

The Dolphin Research Center in Florida estimates that 100,000 marine mammals die each year from eating plastic bags.

WIDECAST estimates that each purse made is removing approximately 70 plastic bags from the environment for a total of 12,000 plastic bags a month. The bags are sold throughout Costa Rica in tourist areas and gift shops and online through http://www.inbio.ac.cr.

They range in color and size and come in various styles including beach bags, calabash bags, messenger bags, water bottle cases, and coin purses. For more information about the project, visit latinamericanseaturtles.org.
