The COP15 Biodiversity Conference failed to tackle the main driver of biodiversity loss: animal agriculture

The COP15 Biodiversity Conference failed to tackle the main driver of biodiversity loss: animal agriculture

Jan 19, 2023

The recent 2022 UN Biodiversity Conference, COP15, came to a close to much fanfare. However, the delegates chose to ignore one of the main causes of biodiversity loss. We cannot continue to ignore the elephant in the room.

Animal agriculture follows the tobacco playbook – and media plays along

Animal agriculture follows the tobacco playbook – and media plays along

Dec 13, 2022

The animal agriculture lobby exploits the news media’s tendency to falsely grant all viewpoints the same scientific legitimacy when reporting on controversial issues. In reality the evidence supporting an immediate and significant shift to plant-based diets is overwhelming. A recent study sheds light on these tactics.

Eating meat leads to longer lives? Beware poorly designed studies with even more poorly interpreted results.

A recently published study claiming that meat eating is causal for longer lives actually shows no such thing.

Corn chips walking: How the overuse of corn in animal agriculture is devastating our environment

Corn chips walking: How the overuse of corn in animal agriculture is devastating our environment

Feb 28, 2022

Animal agriculture has turned humans into massive consumers of corn, doing enormous damage in the process. It doesn’t have to be so. We can stop eating animal products.

Some people argue that hunting is more sustainable than animal farming. In reality, neither is a feasible way to feed humans in even the medium-term future.

Gloomy climate change report offers hope

Gloomy climate change report offers hope

Sep 7, 2021

The recent IPCC report tells us that time is running out to prevent catastrophic global warming. We need to rapidly slash our emissions of carbon dioxide, methane, and other greenhouse gases into the atmosphere. But the report also offers hope. We can rise to the challenge. Going vegan is one of the most powerful ways to do it.

Make your diet as sustainable as you can

Fully plant-based diets are the most efficient and, thus, the most sustainable – by tremendous margins. We can all make changes today to move in the right direction.

Farmed animal sanctuaries: Beacons of light in a very dark world

Farmed animal sanctuaries: Beacons of light in a very dark world

Mar 23, 2021

In the early days, Farm Sanctuary was a shoestring operation. Gene and Lorri funded it by selling tofu hot dogs at Grateful Dead concerts. Over the years, it has grown tremendously.

We’re ruining our soil at a rate that threatens life on Earth – but we don’t have to

We’re ruining our soil at a rate that threatens life on Earth – but we don’t have to

Dec 8, 2020

The United States is losing soil 10 times faster than it can be replenished; the rate of soil loss in China and India is over three times that. Pimentel reports that over just the last four decades of the 20th century, some 30% of the world’s arable land became unproductive. Half of the topsoil in the breadbasket of North America has been lost since 1900.

New science shows immense promise for rescuing ourselves

The authors find that widespread adoption of vegan diets would be – again, by far – the most effective approach.
