Eating and Drinking

Part of the Climate Change exhibition.

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 takeout 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.
