4. Take a Reusable Water Bottle
Millions of barrels of oil are needed to produce the plastic water bottles
annually in US alone, which was enough energy to fuel more than a
million cars and light trucks for a year. You can do your part to curb
emissions by always traveling with a reusable bottle. And coffee and tea
drinkers can help when it comes to saving paper by carrying reusable
travel mugs instead of to-go cups.
