Scientists are jumping on an underutilized protein source that is abundant and environmentally friendly.

Sounds great — until you realize that what the scientists from National Autonomous University of Mexico are suggesting is dining on insects.

Entomophagy, or eating bugs, is already a common practice in over 13 countries, including Thailand, Vietnam, and Cambodia, according to this week's Economist.

And what better then bugs? Gram for gram, bugs provide more nutrients than beef or fish.

And while the Food and Agriculture Organization at the United Nations considers livestock “one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global,” bug farming is a low-impact process.

Khon Kaen University in Thailand has already developed an inexpensive cricket-rearing technique and taught it to 4,500 families. On just a 100 square feet of land, a family can raise enough crickets to make a tidy profit. Or they can even be “grown” inside homes. Because bugs are a crop that doesn’t require much food or water, grows and reproduces quickly, the yield can be incredible.

The Mexican university researchers themselves cite numerous reasons for insect eating: the 75 percent rise in some food prices, the additional 100 million people pushed into poverty, and global warming as reasons to shift to these more sustainable sources of protein.

Of course, there are perils to introducing new species of insects to areas. And there are those who just plain won’t eat bugs.

A more palatable option suggested by the Economist might be to replace supplements in processed food or animal feed with insect-derived protein, which would still help make carnivorous habits a little more sustainable.

I recently came upon a blog by a Chicago woman committed to living as close to a plastic-free life as possible. Her journey to a life without plastic began last September, and over the months her postings about her adventures and increasing knowledge have gathered an audience in the thousands.

The statistics about our reliance on plastics are shocking: According to the U.S. Environmental Protection Agency, the amount of plastic in our waste stream has increased from less than 1 percent in 1960 to 11.7 percent in 2006. And, while Americans drank 50 billion bottles of water in 2006, 38 billion of those ended up in the trash, according to Fast Company magazine.

The anonymous blogger, whose blog is titled Life Less Plastic, explains that she's doing this for personal health reasons, as well to do better by the environment. Among her most popular posts is an entry describing "What I'm Doing to Be Mostly Plastic-Free," which includes:

10. Washing my dishes with Dr. Bronner's bar soap. It works! I'm not kidding!
11. Bringing my own stainless steel coffee mug to the coffee shop. This is important because paper cups are lined with plastic.
12. Bringing along a reusable water bottle or mug for water, and NEVER drinking bottled water.
13. Bringing my own takeout containers to restaurants in case I have leftovers. This sounds embarrassing, but no one has ever even noticed that I've brought my own container except for the people I'm with.
14. Not buying aluminum food cans, excluding canned tomatoes and vegetable broth, which I haven't been able to give up yet. Hopefully, I can/jar some tomatoes this summer and do away with this plastic use, though.

In a society where plastic is pervasive and packaging alternatives are few, even Life Less Plastic's author hasn't been able to do without medicine, which comes in plastic bottles; toothpaste; and even some packaged foods she hasn't been able to find in the bulk section of nearby supermarkets.

Plastics have been around for a while, but we are only beginning to understand their potentially negative consequences. Without plastic, we wouldn't have seen the advances in science and medicine we saw in the last century. However, as the Chicago blogger points out, there are a lot of ways to "live a life less plastic."

Last month, IPS news reported on recent trends toward sustainability and green business within the global economy. According to the January "State of the World 2008" report released by the Worldwatch Institute, "innovative green efforts by governments and business are becoming commonplace." It seems that almost daily, large corporations are announcing their green efforts, however Worldwatch's report warns, many of these announcements are greenwashing.

Can poor countries afford to be green?

A new report, the annually released Environmental Performance Index suggests that poor countries have been justified to disagree with blocs who demand environmental and other green protections even to the opposition of economic growth, according to the Economist. The connection between economic growth and the environment is not entirely clear, the study finds.

“Economic growth, coupled with good governance, may yet prove to be a source of solutions rather than problems. At the moment, perhaps 2 billion people have no formal access to modern energy—they make do with cow dung, agricultural residue and other solid fuels which are far from healthy. Unless foresight and intelligence are applied to the satisfaction of these people's needs, they may embrace the filthiest and most carbon-emitting forms of fossil-fuel energy as soon as they get the chance.”

The report concludes that a combination of growth and transparent government may be the only solution to avoiding this potential disaster. In fact, if developing countries were able to bypass the most polluting stages of their economic development, all parties would be better off.

This week, Norway declared that it will become the world’s first carbon-neutral country, by 2030. It turns out that the idea of “going carbon-neutral” is becoming quite the fashion around the globe, though – and Norway might find more competition than it bargained for: In 2007, Costa Rica announced it's intention to become carbon neutral by 2021, the 200th birthday of the Central American country. If Costa Rica meets its goal, it will beat Norway to claim the title of first carbon neutral country.

Update: In the weeks since this was posted, the United Nations has launched the Climate Change Network, which aims to unite global responses to climate change. Since Norway announced its intention to go carbon-neutral, three more countries have made the same declaration: Iceland, New Zealand, and Monaco. A National Geographic News article posted in March figured that Costa Rica was most likely to win the race to carbon-neutrality, considering for example that 80 percent of that country’s energy comes from renewable resources already.

The Economist recently took a look at how the process of recycling is helping to sustain one community in India. The dalits, a lower caste of Hindu, are participating in an economy that not only provides them with income, but helps to reuse some of India's waste.

Disposable plastic cups are many times reborn in Dharavi. In a spiralling continuum, they are discarded and gathered in, melted down to their polypropylene essence, and re-moulded in some new plastic form. Recycling is one of the slum's biggest industries. Thousands of tonnes of scrap plastic, metals, paper, cotton, soap and glass revolve through Dharavi each day.
