Eating and Drinking
Reducing food packaging
Buying unwrapped is okay
Most fresh fruits and vegetables don't need those layers of plastic.
Avoiding bottled water
It's healthy to drink water, but packaging and shipping it requires energy.
Limiting disposable containers
Plastic take-out containers and utensils, plastic bags and individualized packets all require energy to manufacture.
Factoring in transportation
Flying, trucking and shipping foods around the world uses oil, so buying local foods can reduce "food miles" emissions. But there are tradeoffs: sometimes growing foods close to home creates as much or more CO2.
Considering food choices
Buying seasonal foods
Eating more fruits, grains and vegetables
The livestock sector emits about 2.8 billion metric tons of CO2 each year--roughly 9 percent of the world's total--and is responsible for about 7.2 billion metric tons of all greenhouse gas emissions (including methane), or roughly 18 percent of the total.
