This post is from Zen Habits Journal - I have chosen 3 of his points that go hand in hand with ChicP's ethos. He states that these individual choices are all small measures but you may as well start now...
1. You’re better off eating vegetables from Argentina than red meat from a local farm.
Eating local is lovely, but most carbon emissions involving food don’t come from transportation — they come from production, and the production of red meat and dairy is incredibly carbon-intensive.
Emissions from red-meat production come from methane, a potent greenhouse gas. Experts disagree about how methane emissions should be counted in the planet’s emissions tally, but nearly everyone agrees that raising cattle and sheep causes warming that is an order of magnitude morethan that from raising alternate protein sources like fish and chicken (the latter of which have the added benefit of creating eggs).
According to researchers at Carnegie Mellon, a typical household that replaces 30 percent of its calories from red meat and dairy with a combination of chicken, fish and eggs will save more carbon than a household that ate entirely local food for a full year.
Yes, eating nothing but locally grown fruits and vegetables would reduce your carbon footprint the most. But for people not ready to make that leap, reducing how much meat you eat matters more than going local.
2. Eat everything in your refrigerator.
Scientists have estimated that up to 40 percent of American food is wasted — which amounts to almost 1,400 calories per person every day. Food waste occupies a significant chunk of our landfills, adding methane to the atmosphere as it decomposes. Even more important, wasted food adds to the amount of food that needs to be produced, which is already a big part of our carbon load.
How can you waste less? For food shopping, plan out meals ahead of time, use a shopping list and avoid impulse buys. At home, freeze food before it spoils. If you find yourself routinely throwing prepared food away, reduce portion sizes.
3. Buy less stuff, waste less stuff.
It’s not just car manufacturing that adds to carbon emissions. Other consumer goods can have a huge impact: Making that new MacBook Proburns the same amount of carbon as driving 1,300 miles from Denver to Cupertino, Calif., to pick it up in person.
At the other end of the product life cycle, reducing waste helps. Each thing you recycle is one fewer thing that has to be produced, and reduces the amount of material that ends up in landfills. But the recycling process consumes energy as well, so — depending on the material — it may not be as helpful as you might think. Recycling a magazine every day for an entire year saves less carbon than is emitted from four days of running your refrigerator.
It’s better not to consume the raw materials in the first place, so you may want to think carefully about whether you’re really going to use something before you buy it.
Of course, these individual choices are all small measures.
A sustainable solution that avoids severe damage to the planet will require fundamental changes in the global energy system: transitioning from fossil fuels to renewable energy and sharply reducing the number of cars that run on internal-combustion engines.
Advocating public policies that support the development of clean energy and efficient transportation is probably the most climate-friendly thing you can do. But cultural and behavioral change can be part of the solution as well. Might as well start now.
