Thursday is World Environment Day, and you will no doubt celebrate by donating to Grist. (Thank you!) Once you’ve got that out of the way, you can also help out our dear environment by packing a lighter suitcase when you travel, jogging in the park instead of on the treadmill, using a wind-up alarm clock, and ditching your electric toothbrush, says a 202-page United Nations report called “Kick the Habit! Towards a Low Carbon Economy.” That kicky title is also the official slogan of this year’s World Environment Day. New Zealand, which is striving to become a carbon-neutral country, will host the main international celebrations of the day. But if you don’t live in Wellington, look for a rally, parade, concert, reading, tree planting, and/or clean-up campaign near you.
