| | What can you do to fight climate change? A few tweaks in your diet may be a good start—and make you healthier.
And you don’t have to go vegan. A Purdue University study, analyzing more than 57,000 U.S. households, found just three changes could shrink the food carbon footprint of 7 in 10 Americans.
Not only are high calorie/low nutritional foods like candy, soda, and packaged snacks bad for you, they’re a tenth of the average family’s food carbon footprint. The study advises families to cut them—as well trim purchases of ready-made foods or bulk orders, some of which often end up in the garbage. (Nearly 40 percent of U.S. food production is wasted). Doing these things at the supermarket could cut a family’s food carbon footprint a quarter, with massive positive effects if many people do it.
Read more about cutting your family’s effect on climate change in the April edition of National Geographic. (Pictured above, Tina Nielsen-Hodges weighs an eggplant at a food co-op in Ithaca, New York.)

| Free again! Researcher and ecologist Joshua Griffiths gently releases a young female platypus that was captured just 20 minutes earlier as part of a program to monitor and understand the local population. The venomous, egg-laying mammal is under increasing threat in eastern Australia as climate change, drought, and human development ravage the rivers the animals rely on. See the video on our Instagram page.

3 WAYS TO HELP ENDANGERED SPECIES
1. Use less water, which leaves more to be released back into rivers.
2. Pick up litter, which can wash into waterways and impact freshwater wildlife.
3. Support wild places being kept wild.

Since 2008, the initiative has worked to inspire the creation of protected areas where marine life can thrive—and to ensure effective management of those areas. Read the full announcement here. (Pictured above, a sanctuary around the Colombian island of Malpelo was expanded after a 2018 Pristine Seas expedition.)
