Reducing Food Waste
We have talked about food waste before. It is a big problem in this country: some 31% of our food supply is wasted, more than 130 billion pounds a year. Food waste makes up 21% of solid waste in municipal landfills, which means that it accounts for the bulk of landfill methane emissions. Methane is more than 20 times more effective as a greenhouse gas than carbon dioxide, and landfills are a major source of it.
Killer Air
Globally, air pollution kills 3.3 million people per year. And this number could double to 6.6 million people by 2050 if little is done to decrease the dangerous levels of tiny particles, toxins, and ozone in the air.
The Trouble With Sustainability
Since its inception, sustainability has been human-centric. It came into vogue in 1987, with the publication of a UN report called Our Common Future, which defined sustainable development as: “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
Reducing Methane In The Atmosphere
Methane is the main component of natural gas. It is also a potent greenhouse gas, having 25 times the heat trapping ability of carbon dioxide.
Whine While You Can
There are lots of potential impacts associated with global climate change – shifts in the distribution of plants are among them. Most plant species are adapted to a range of climate conditions. If the climate changes, their habitat can shift as well. This is true for crop and forestry plants, as well as native species.
Less Beef
In the Northeast, grilling season is almost over. While many will miss backyard barbecues, it’s high time that we rethink the American summer ideal of a thick, juicy steak.
Earth Overshoot Day
Earth Overshoot Day is the day when, according to estimates, the total combined resource consumption of all human activity on the planet reaches the total amount that the Earth can generate for the year. It is the natural resource equivalent of the date by which you have spent your entire salary for the year.
A New Labeling Initiative
Hydraulic fracturing – or fracking – is a well-stimulation technique in which rock is fractured by a pressurized liquid to free otherwise trapped natural gas or oil.
Meat Consumption & Biodiversity
Several studies warn that the current loss and decline of species is contributing to what appears to be the beginning of earth’s sixth mass extinction. More than 400 species have gone extinct in the last 100 years. And scientists suggest up to 37 percent of the world’s species could go extinct within the next 35 years.
Bumblebees And The Climate Squeeze
Bumblebees face their share of hazards – habitat loss, disease, and harmful pesticides among them. New research shows that climate change is also a significant threat to bumblebee populations in Europe and North America. In fact, University of Ottawa scientists suggest that, for these bumblebees, climate change may be the biggest threat of all.
Climate Change And Lobster
It’s no secret that ocean waters are warming, especially in New England. The waters in the Gulf of Maine are warming 99% faster than the rest of the world’s oceans. What’s the problem? Well, lobsters like cold water, and as a result, they’re heading north.
A Giant Red Tide
Red tide is the common name for algal blooms in the ocean. These are typically cyclical events that occur along our coasts and generally last a few weeks.
Obesity And Food Energy Supply
Obesity is a global health problem and is on the rise in many countries. There are many factors involved in the increasing prevalence of obesity such as increased urbanization, car dependence and sedentary occupations. Of course, the prime culprit is generally thought to be that we eat too much.
Too Warm For Seal Hunting
In the far north of Alaska, generations of hunters have traversed the broken sea ice of Kotzebue Sound every late June and early July hunting for bearded seals. A single seal can supply hundreds of pounds of meat, enough to feed a large family for an entire winter. Its meat and oil products are an important food source.
More About Food Waste
Yesterday we talked about the fact that Americans throw out nearly half of the food they buy. The worst thing about this is that one in seven Americans – over 46 million people – don’t know where their next meal is coming from.
Food Waste
We recently talked about the problem of food waste on this program, in particular, the 1.3 billion tons of food wasted around the world each year. This is a tragic situation given how many people around the world don’t have enough to eat.
It’s National Farmers Market Week!
Are you familiar with the farmers markets, CSAs, and food hubs near you? Do you know what products are for sale and what forms of payment are accepted? Can you find these places while on vacation?
Organic Versus Conventional Food
When you buy organic food, you expect that it has been produced without genetically modified seeds, artificial fertilizer, or pesticides. A scientific review of 50 years of data suggests that organic and conventional foods have similar nutritional content – yet many pay considerably more for organic products, believing they are healthier.
