CHICAGO (CBS)– Author and environmental expert Ashlee Piper joined CBS 2’s Suzanne Le Mignot to share her tips for helping the environment and making sustainable lifestyle shifts.

Week 1: Go Meatless
One of the most potent ways to help the planet, according to Piper, is to reduce meat consumption. Piper recommends LYFE Kitchen for vegan and vegetarian meals.

Week 2: BYO Everything
Eliminate trash by “bringing your own” water bottles or silverware. Piper says S’well water bottles keep drinks hot or cold.

Week 3: Revamp Your Regimen
Piper said personal care products use a lot of plastic and can be tested on animals. “Seed Phytonutrients hair care — vegan, cruelty-free, and natural luxury products that perform beautifully and can be found at Sephora and Whole Foods,” Piper stated.

Week 4: No New Things
Shop second hand and reuse items in order to eliminate new items. Piper said the benefit is also the lower costs of buying used items.

Piper said April is Earth Month, which is a great time to try out these new tips.
