Trouble For Sardines
In the 1950s, there was a huge collapse of the West Coast sardine population as a result of intense overfishing that coincided with a natural down-cycle related to cooler water temperatures. That crash resulted in the virtual shutdown of the largest fishery in the Western Hemisphere, closing down the famed Cannery Row in Monterey, California.
To Bee Or Not To Bee
No one likes pests: mosquitoes at your barbeque, termites in your basement, caterpillars on your garden vegetables and field crops. During the past 70 years, the chemical industry has developed an arsenal of chemicals designed to eliminate pests.
Useful Byproducts From Coffee Roasting
Coffee is the second most valuable commodity in the world after oil. This $100-billion-dollar-a-year industry plays a major role in the global economy. It also has a significant impact on the environment. Processing coffee produces more than 2 billion tons of byproducts annually.
Reducing Food Waste
Wasted food is one of the greatest economic and environmental problems in the world today. According to a United Nations study, one-third of the world’s food winds up spoiled, rotting in fields, or is thrown away. This amounts to 1.3 billion tons of food wasted annually while at the same time nearly 900 million people around the world go hungry every day.
The Biofuel Crop Dilemma
The demand for biofuels continues to grow. Producing fuels from plant matter is considered to be a carbon-neutral way to get energy and is an important part of efforts to move away from fossil fuels.
The Downside Of Nitrogen Fertilizer
Yesterday, we introduced the topic of synthetic nitrogen fertilizer. Anyone with a lawn or a garden is familiar with the product. But prior to the 1950s, it use was not the norm.
Too Much Of A Good Thing
Bags of garden fertilizer are labeled with three numbers, such as 15-4-5. These numbers indicate the percent of nitrogen, phosphorus, and potassium in the product. The remainder of the bag is filler that helps the fertilizer disperse.
Protecting Working Forests
The U.S. has more than 420 million acres of “working” forests, which provide timber for construction, as well as pulp for paper and packaging. Apart from these economic benefits for communities, such forests provide clean air and water and wildlife habitat. Nearly 45 million acres of these forests are at risk of being lost to development.
When Planting Trees Is Bad For Biodiversity
Over the past decade, more than five million acres of forests and farms worldwide have been cleared for agro-industrial rubber plantations. The driver is the growing demand for rubber products – especially tires – which use 70% of the annual rubber production.

Human Pollution And Fish
We recently spoke on this program about how up to 28 billion pounds of plastic debris enters the world’s oceans every year. Well now a new study has shed some light on how this and other human-caused pollution may be impacting deep-water marine fish.
McDonald’s And Antibiotics
McDonald’s – the world’s largest chain of hamburger fast food restaurants – recently announced plans to source chicken that is free of human antibiotics. The corporation, which is one of the country’s biggest buyers of chicken, is trying to shake its image of offering unhealthy and unnatural foods. The transition to this cleaner meat will take two years.
Perennial Rice
Rice is the most economically important crop in the world. It supplies humanity with about a quarter of its calories. Domesticated rice is a short-lived plant that generally dies off after it produces seeds. Rice paddies have to be cleared of vegetation and plowed each year and are highly vulnerable to soil and nutrient loss through erosion, soil compaction and decline in organic matter.
Are Weed Killers Killing Us?
The U.S.-based agrochemical giant Monsanto finds itself at the forefront of another controversy. Monsanto, which dominates the agriculture market with its genetically modified seeds and herbicides, has drawn unwanted scrutiny after a new report linked one of its most popular herbicides to potential health hazards.
The True Cost Of Meat
It’s not uncommon for Americans to eat meat at every meal – bacon with breakfast, a turkey sandwich at lunch, steak for dinner. Worldwide, meat production has more than quadrupled since the 1960s, when more meager portions were the norm. And mass production has driven prices down considerably.
GMO Apples
In February, the first genetically engineered apples were approved for planting and sale in the US by the Department of Agriculture. Two varieties, known as the Arctic Granny and Arctic Golden received the approval. They are genetically engineered to resist browning.
The Dirty Job Of E-Waste Recycling
“Reduce, reuse, recycle” was a popular mantra of the 80s and 90s, encouraging citizens to separate paper, plastic, and aluminum from their trash. But with the exponential rise of electronics like cell phones, laptops, and tablets – recycling has become more complex.
Manure To Energy
Dairy cows are very industrious. On average, they produce about 70 pounds of milk a day. Unfortunately, they also produce about 150 pounds a day of manure. Basically, it is an inevitable byproduct of the production of milk.
Food Waste: Now Illegal In Seattle
Previous Earth Wise segments have explored the global problem of food waste. In developing nations, inefficient harvesting and poor storage result in less than half of produced crops making it to the marketplace. In the U.S., food waste tends to occur in grocery stores, homes, and restaurants.
