James Cameron: Eating meat-free to save the planet

“We can just change what we eat,” explains Cameron. “Just eat less meat and dairy and your carbon footprint drops way down.”

When U.S. President Barack Obama visited Beijing last November, he and Chinese President Xi Jinping announced a landmark joint agreement to fight the effects of climate change. It committed the two nations to reducing planet-warming carbon emissions and cemented a first-ever pledge by China to stop its emissions from growing by 2030.

The accord was widely hailed as a crucial first step toward prompting other nations to make their own greenhouse gas cuts. This as a new global agreement on curbing climate change is expected to be signed this fall, by every nation around the globe, at a United Nations summit in Paris.

Experts Say Change In Diet Is Instrumental In Ending Hunger

The U.N. plan to end worldwide hunger by 2030 focuses on eating more vegetables and reducing food waste.

oes everyone in your family, group of friends or workplace have the same diet? While I love chocolate, I have friends who can’t eat it. Some friends and family are strict vegetarians while others rarely eat a vegetable. Some people may start their day with a smoothie or eggs and bacon or maybe even just a cup of coffee. Some people go hungry.

How people eat is dependent on a number of factors and could vary greatly around the world. Reuters reports that "world leaders are set to endorse a U.N. goal to eliminate hunger by 2030” later this month, but doing so requires the adoption of new eating habits. The change must occur across the board, from the wealthy to the developing nations.

Part of that change, according to Reuters, involves consuming less red meat, reducing food waste and fighting poor nutrition.

"Sustainable and healthy diets will require a move towards a mostly plant-based diet," Colin Khoury, a biologist at the Colombia-based International Centre for Tropical Agriculture, told Reuters.

There are 795 million people who go hungry each night, Reuters reports. To achieve zero hunger by 2030, we need enough food worldwide to feed them—not just any food, but sustainable, transportable food that will still be viable upon arrival (in other words, less meat and more grains, fruits and vegetables). If meat was eaten only once a week, commodity prices would decrease "as less grain would go to feed animals, making food cheaper for the urban poor,” according to Reuters.
