Just below the water’s surface lies a magical world teeming with life and value. Coral reefs are home to 4,000 fish species and provide the world with goods and services — such as jobs, foods, medicines and storm protection — worth $375 billion annually.
But scientists estimate that 70% of all corals reefs could be lost by 2050 if current rates of destruction continue — from factors ranging from overfishing to climate change.
Planting biofuel crops on converted forestlands or other ecologically valuable lands has already become a hotly debated practice.
Now, a new report co-authored by Nature Conservancy scientists says that biofuel crops could also become invasive species — and that the risk needs to be evaluated before these crops are planted.
They go by the boisterous acronym MEND, or the Movement for the Emancipation of the Niger Delta, and they are lethal. As political students of Niccolò Machiavelli, they have crafted Machiavellian tactics to a fault, and boast about shutting oil pipelines in their motherland to get the ears of their sullen government and the rest of the capitalist world which is driven by its lust for oil.
But they don’t just boast, they actually engage in hostage taking and abduction of foreign oil workers working in Nigeria’s oil rich but socio-economically poor Delta region for ransom (they call it pollution reparation); sometimes killing them and even bombing oil pipelines for effect.
MEND said in an email circulated to news media in January 2006: “It must be clear that the Nigerian government cannot protect your workers or assets. Leave our land while you can or die in it…. Our aim is to totally destroy the capacity of the Nigerian government to export oil.”
Editor’s note: Our friends at Low Impact Living point out 10 ways you can save energy this summer. This post was originally published on June 10th, 2008.
The heat of summer is coming, and that means many of us are about to crank up the AC, make an extra batch of ice, and generally burn energy like it’s our job. But we need all need to continue to try to conserve as much energy as possible to conserve resources and slow the march of global warming. And we get to save money at the same time–woo hoo to that!
Here are the ten things we can all do at home to cut our energy consumption. We start out nice and easy, then ramp up to some extra-credit methods at the end of the list for you Climate Crusaders.
Not exactly washing without water, but with less than 2% of a normal washing machine. That’s only 1 cup of water for those sweaty gym clothes, grubby kid-wear, and foul socks.
Washing with soap and water has been THE WAY to clean most clothes for so long, it’s hard to imagine reducing H2O by 98%. What this technology lacks in sexy bells and whistles, it gains in implications. Billions of gallons of clean water could be conserved every year simply by adopting this dry cleaning technology. Less water also means less drying, which can add energy savings to those with energy-hungry clothes dryers.
Editor’s note: Green building and resource conservation doesn’t have to involve the latest technology or high prices. Our friends at GreenBuildingTalk take a look at one of the humblest of water-saving devices — the faucet aerator — and show how this low-tech option is a good bet for homeowners looking to conserve water… and lower their bills. This post was originally published on Sunday, June 1, 2008.
About a decade ago, water conserving faucets and low-flow showerheads were the bane of contractors and homeowners alike. But over time, trial and error has led to better product design, education and installation. If your kitchen or bathroom faucet is fairly new, it will probably have an aerator in it. New faucets today typically have 2.2 gallons per minute (gpm) aerators, whereas conventional faucets typically use 4 gpm. If your faucets are more than ten years old, odds are they’re water hogs. Aerators provide a low-tech solution that not only make the flow more forceful, but provide more effective wetting and rinsing. Consider installing an aerator with a lower flow, such as 1.5, 1.0, or the lowest option available to date: .5 gpm.
Editor’s note: Just like our friends at Low Impact Living, we’ve got passion for saving water… so we were very happy to see this post about a new technology for homeowners interested in doing just that! LIL writer Jason Pelletier originally published this post on Wednesday, May 28, 2008.
I’m often pleasantly surprised at how much interest and passion you (our visitors) display for water-saving technologies. 
Renewable energy is sexy, and eco-friendly cars are top-of-mind for most people these days, but graywater systems? Rain barrels? Rain gardens? Even water-conserving toilets and showerheads? They’re pretty hot too … I for one am thrilled, for not only have I spent a good part of my career designing stormwater treatment systems but I believe that water shortages are a pretty pressing and difficult environmental challenge that doesn’t get enough attention in these days of $4 gasoline and global warming.
The beauty of any of these water-saving technologies is that a) they achieve multiple benefits, saving water while reducing wastewater or stormwater runoff and b) you can see the results right at home. It’s pretty satisfying to open the valve on a rain barrel, see the water flow out and know that you reduced pollution downstream and also prevented water from being siphoned from lakes or rivers tens or hundreds of miles away.
There are some challenges, though. In order to really make a dent in your runoff, you might have to use ten or more rain barrels - not so great if you don’t have space or your downspouts are on the visible side of your house (or if you’re not Ed Begley Jr and just don’t care!). Cisterns give you more capacity, but you’re talking about a real construction project with some possible permitting hurdles.
Editor’s note: Today’s final installment of Low Impact Living’s “A Thirsty Nation” focuses on steps you can take to conserve water around the home. Make sure to check out the previous two posts in this series on water use and conservation, or take a look at the whole report on Low Impact Living’s site.
For many homeowners in the southern United States, lawn irrigation is likely the largest source of residential water waste. There are many things one can do to correct this.
Adjust your irrigation controller to fit your climate conditions and landscaping. This alone can produce water savings of over 30%. Some water utilities offer water audits, so check with your local water provider to see if they offer this service. Or, find experienced landscape maintenance firms in your area.
Install rain and soil moisture sensors. Many people don’t turn off their irrigation when it rains. Also, most lawns receive far more water than they actually need when it isn’t raining. Both problems can be corrected using sensors attached to your irrigation system. See examples.
Replace existing landscaping with climate-appropriate options, keeping grass to a minimum. The biggest challenge with many yards is that they are composed of plants originally from other areas with vastly different climate conditions. The typical turf lawn can use up to 40 inches of water a year or more; many climate zones in the US have far less than that in rainfall. What most people don’t realize is that all regions of the US have native plants that are beautiful, durable, and adapted to local climate conditions. Some native grasses can provide the benefits of turf while requiring 1/3 of the water. So, if you really want to save water and also want to stand out on your block, cut down your turf use and rebuild your lawn using beautiful natives. Find landscape architects in your area who can help.
I remember vividly the sight of my dad running for cover, making slow groaning sounds, thrashing wildly at the air like some madman from a B-movie.
I was a mere toddler, blanket in one hand, thumb in mouth (think Linus) - wondering what all the fuss was about.
It was dusk and the bats were out, darting this way and that, catching insects as the summer’s sun slid from view, leaving that beautiful blue light before darkness descends.
I shrugged in an awfully precocious manner, looked at mummy, then turned my eyes back to the bats.
And today, Defra (the UK’s Department for Environment, Food And Rural Affairs) have announced that bats are to be used to help measure the biodiversity of the UK.
Editor’s note: On Monday, we published the first part of Low Impact Living’s report on American water use at sustainablog. Today’s second part takes a look at how we tend to use water excessively in our own homes. Keep an eye out for part 3, which will give you tips for reducing your water consumption, or visit LIL for the original publication of the report.
There are many sources of water waste across all sectors of the economy. But, as homeowners and consumers, which ones do we have the most control over? Low Impact Living suggests you consider the following ideas when thinking about lowering your water use.
Direct Household Water UseThe typical household with three members uses over 300 gallons of water per day, both inside and outside. If you live in a warm climate where lawn irrigation is needed, then typically this is your single biggest source of waste – most lawns are over-watered, irrigated with inefficient equipment, and planted with plants not suitable to the local climate.
Inside, toilets, clothes washers and showers are the largest water users, representing 19, 15 and 12 gallons per person per day respectively (see chart to the right). There are huge inefficiencies here as well, especially in older homes. New appliances and plumbing fixtures can often shave 50% off of your water use.
All told, an average water-conserving home could cut the 300 gallon average above to less than 150 gallons with no sacrifice in comfort or performance. Specific things you can do to achieve these savings are listed below.
In addition to the water that you use directly, you also consume water via the products and services that you buy.
