Less Meat and Dairy for a Healthier FutureTake action
How using land better is a vital part of surviving the climate crisis
If we want to keep both our bodies and our planet healthy, we need to make big changes to the way we look after the land.
Using ecological farming practices and giving more of the land back to nature is critical in guarding against the climate crisis, providing enough food for everyone, and to ensure the survival of Indigenous Peoples around the world.
Unfortunately, a major new report from the Intergovernmental Panel on Climate Change – the UN body providing the scientific analysis informing global action – reveals how land of all types (forests, grasslands and wetlands to name a few) is being mistreated, causing a host of social and environmental problems.
Ironically, the way we produce our food is causing many of these problems. Industrial agriculture has expanded across the planet at a phenomenal rate, chewing up forests and other natural areas to produce cheap crops and meat.
Here are the top five reasons we should take more care with the land.
Using land wisely will combat the climate crisis
Forests provide an essential buffer against the ongoing climate breakdown. Large, healthy forests are vital if we are to keep global heating below 1.5ºC, the level needed to keep the climate under control, as are other natural areas like grasslands and wetlands. They draw down carbon dioxide from the atmosphere to lock it away in plant matter and the soils. So the remaining forests need to be protected, damaged forests allowed to recover and millions of native trees planted to restore natural forests (rather than creating commercial tree plantations which don’t have anywhere near the same impact on reducing emissions).
But what’s happening instead is that forests and grasslands are being torn up at an ever-increasing rate, largely by industrial agriculture. The drive to produce cheap meat has seen vast areas of forest being replaced with enormous cattle farms and soya plantations to feed cows, pigs and chickens. Converting forests into agricultural land releases carbon emissions. So it’s no surprise that nearly a quarter of global emissions comes from agriculture, forestry and other types of land use, and meat and dairy production is responsible for a significant proportion of those.
Cutting back on the amount of meat and dairy we produce and eat will reduce the amount of forests being converted into agricultural land. Reducing meat consumption around the world by 50% in the next 30 years (and by even greater amounts in regions where meat consumption is already high, like Europe and North America) is crucial to slash emissions and fight the climate crisis.
Looking after the land means looking after wildlife and plant species…
It’s no secret that forests, grasslands and other natural areas are havens for wildlife and plant species. These hotspots of natural richness contain thousands upon thousands of species, many of which have yet to be studied or even discovered by scientists.
As these natural landscapes are converted into industrial agricultural land, this richness is being replaced by huge areas dominated by only a few species – domesticated livestock and plantation crops like palm oil and soya. Many wild species are being pushed to the brink of extinction, and the recent report from the UN’s IPBES warns that up to one million species face extinction because of human activity.
To prevent this, the relentless expansion of industrial agriculture needs to be halted and natural areas restored so they can continue to support the bewildering variety of life found on our planet. Not only that, adopting ecological farming practices will reduce the use of chemicals like pesticides – good news for the bees and other insects which are in serious decline.
…and ensures the survival of Indigenous Peoples
All over the world, Indigenous Peoples’ rights have been disrespected, resulting in the destruction of their lands and genocide. Not only that, but Indigenous Peoples are subject to intimidation, violence, and even murder as they come into conflict with companies and governments trying to exploit their land, whether for mining, logging or industrial agriculture.
Indigenous Peoples represent less than 5% of the world’s population. Yet collectively, their lands hold over a third of all remaining natural areas and they are on the frontlines fighting to defend forests and other natural areas. Studies have shown that areas governed by Indigenous Peoples contain more biodiversity than elsewhere. The new IPCC land report is clear that respecting and supporting Indigenous Peoples is vital to make sure forests and other natural areas are healthy and well-managed.
Healthy land means fertile soils
Stripping away the natural vegetation to farm intensively is bad news for the soil. Using the same land to produce multiple harvests each year and the extensive use of agrochemicals have caused considerable damage to soil fertility. According to the UN, a third of all land has been degraded and we’re losing 24 billion tonnes of fertile soil every year. Clearly, this will have an impact on our ability to produce food.
Cutting back on meat-heavy diets and replacing intensive farming with a more ecological approach will reduce pressure on the land and maintain soil fertility. And soil is another major carbon storage space, so keeping soils in good condition is another natural solution to the climate crisis.
It will even improve our own health
One in nine people on the planet suffer from hunger because they haven’t got enough to eat, so it doesn’t make sense to use so much land growing crops to feed animals or produce bioenergy. Using that land to grow food for people instead means providing enough food for everyone. But for that, we need to reduce the amount of meat and dairy we produce and eat.
Growing crops for people to eat is a much more efficient use of land. Shifting to largely plant-based diets with more vegetables, fruit, nuts and pulses will mean less land is needed for agriculture and more can be given back to the forests. Cutting back on meat can also reduce the risk of medical conditions such as heart disease and type 2 diabetes and can ultimately add up to three and a half years to people’s lives.
Making these changes is not only good for our health, but the health of the planet.
