Diet and the Environment

TED talks to watch and think about the impact of diet on the environment and you.

What's wrong with what we eat

In this fiery and funny talk, New York Times food writer Mark Bittman weighs in on what's wrong with the way we eat now (too much meat, too few plants; too much fast food, too little home cooking), and why it's putting the entire planet at risk.

Why not eat insects?

Marcel Dicke makes an appetizing case for adding insects to everyone's diet. His message to squeamish chefs and foodies: delicacies like locusts and caterpillars compete with meat in flavor, nutrition and eco-friendliness.

Hidden toxins in the fish we eat

What's link between the ocean's health and our health? Marine biologist Stephen Palumbi shows how toxins at the bottom of the ocean food chain find their way into our bodies -- and tells a shocking story of toxic contamination in the fish market, where consumers were being tricked into buying fish that's not only mislabeled but unsafe.

Choice, happiness and spaghetti sauce

"Tipping Point" author Malcolm Gladwell gets inside the food industry's pursuit of the perfect spaghetti sauce -- and makes a larger argument about the nature of choice and happiness.

The global food waste scandal

Western countries throw out nearly half of their food, not because it's inedible -- but because it doesn't look appealing. Tristram Stuart delves into the shocking data of wasted food, calling for a more responsible use of global resources.

Save the oceans, feed the world!

What's a marine biologist doing talking about world hunger? Well, says Jackie Savitz, fixing the world's oceans might just help to feed the planet's billion hungriest people. In an eye-opening talk, Savitz tells us what's really going on in our global fisheries right now - it's not good - and offers smart suggestions of how we can help them heal, while making more food for all.

Obesity + hunger = 1 global food issue

Co-creator of the philanthropic FEED bags, Ellen Gustafson says hunger and obesity are two sides of the same coin. In her talk, she launches The 30 Project -- a way to change how we farm and eat in the next 30 years, and solve the global food inequalities behind both epidemics.

Ending hunger now

Josette Sheeran, the head of the UN's World Food Program, talks about why, in a world with enough food for everyone, people still go hungry, still die of starvation, still use food as a weapon of war. Her vision: "Food is one issue that cannot be solved person by person.

We need to feed the whole world

Louise Fresco shows us why we should celebrate mass-produced, supermarket-style white bread. She says environmentally sound mass production will feed the world, yet leave a role for small bakeries and traditional methods.

The other inconvenient truth

A skyrocketing demand for food means that agriculture has become the largest driver of climate change, biodiversity loss and environmental destruction. At TEDxTC Jonathan Foley shows why we desperately need to begin "terraculture" -- farming for the whole planet. (Filmed at TEDxTC .)

Why I'm a weekday vegetarian

We all know the arguments that being vegetarian is better for the environment and for the animals -- but in a carnivorous culture, it can be hard to make the change. Graham Hill has a powerful, pragmatic suggestion: Be a weekday veg.
