Vegan Diet: Helping People, Saving The Planet

A vegan diet is widely believed to be better for the planet and for people than diets that include animal products. Research shows that meat and dairy products are fuelling the climate crisis, while plant-based diets—focused on fruits, vegetables, grains, and beans—help protect the planet and human health. A vegan diet can help reduce greenhouse gases, preserve water and land, and save lives.

A vegan diet can help reduce greenhouse gases

Secondly, animal agriculture is a highly inefficient use of resources. It requires a large amount of land, water, and energy to produce meat and dairy. For example, it takes about 11 times as much fossil fuel to produce a calorie of animal protein as it does to produce a calorie of plant protein. By contrast, plant-based diets focused on fruits, vegetables, grains, and beans are much more resource-efficient and have a lower environmental impact.

Thirdly, livestock farming contributes to deforestation, which further exacerbates climate change. Forests act as carbon sinks, absorbing greenhouse gases from the atmosphere. However, vast areas of forests, particularly in the Amazon rainforest, have been cleared to create pastureland and grow crops for livestock. This not only reduces the planet's ability to absorb carbon dioxide but also releases stored carbon into the atmosphere.

Additionally, livestock themselves produce significant amounts of greenhouse gases, particularly methane and nitrous oxide. Methane is released during the digestive process of ruminants, such as cows and sheep, and from the storage and management of animal manure. Nitrous oxide is released from manure and fertilizer use on farms. These gases have a much stronger warming effect on the atmosphere than carbon dioxide.

Finally, a global shift towards plant-based diets can help reduce greenhouse gas emissions by decreasing the demand for animal agriculture. This would lead to a reduction in the emissions associated with livestock farming and allow for the recovery of biomass in natural ecosystems. According to a study by Stanford University and the University of California, Berkeley, phasing out animal agriculture over 15 years could have the same effect as a 68% reduction in carbon dioxide emissions through the year 2100.

How a Vegan Diet Helps Starving People and the Planet

Agriculture accounts for about 70% of freshwater use, making it the world's largest water-consuming sector. Meat and dairy products lead the way in agricultural water use. Producing just one pound of beef requires 1,800 gallons of water—that's the equivalent of about 100 showers for the average American. A kilogram of mangoes requires 686 litres of water, while the same amount of plums needs 305 litres.

If the United States cut animal product consumption in half, its food production would require 37% less water.

Animal products have a large environmental footprint on our croplands. Agriculture occupies 40% of Earth's ice-free landmass, and more than three-quarters of this is used for livestock production, despite meat and dairy making up a much smaller share of the world's protein and calorie supply.

Another study projected that if Americans ate more beans and less beef, 42% of cropland could be freed up.

Other benefits of a vegan diet

• Reducing greenhouse gases: Food production is responsible for up to 30% of total greenhouse gas emissions, with animal products accounting for about three-quarters of these effects.
• Alleviating hunger: Animal agriculture uses resources inefficiently. More than 820 million people around the world lack sufficient food, and almost two-thirds of all soybeans, maize, barley, and about a third of all grains are used as feed for animals.
• Improving health: Eating more plants and fewer animal products could prevent 10.9 to 11.6 million premature deaths from heart disease, diabetes, and other chronic conditions every year.

It can help save lives

A vegan diet can help save lives in several ways. Firstly, it can reduce the number of premature deaths from heart disease, diabetes, and other chronic conditions. According to researchers, eating more plants and fewer animal products could prevent 10.9 to 11.6 million premature deaths each year.

Secondly, a vegan diet can help address world hunger by increasing the food supply. Animal agriculture is an inefficient use of resources, as it requires more water, land, and energy than plant-based alternatives. For example, the water footprint of beef is twenty times higher than that of cereals and starchy roots. By contrast, plant-based diets require significantly less land. If everyone in the world adopted a vegan diet, we could reduce land use for agriculture by 75%. This would free up resources and increase access to food, helping to address world hunger.

Additionally, a vegan diet can help mitigate climate change, which is a leading cause of global hunger. Animal agriculture is a significant contributor to climate change, accounting for up to 30% of total greenhouse gas emissions. By shifting to plant-based diets, we can substantially reduce these emissions and mitigate the impacts of climate change on food security.

Lastly, a vegan diet can improve human health by reducing the consumption of unhealthy animal products, which are linked to an increased risk of chronic diseases. By contrast, plant-based diets are rich in fruits, vegetables, grains, and beans, which provide essential nutrients and promote better health outcomes.

In conclusion, a vegan diet has the potential to save lives by reducing premature deaths, addressing world hunger, mitigating climate change, and improving human health.

It can help fight climate change

A vegan diet can help fight climate change by reducing the amount of greenhouse gas emissions associated with food production. According to a report by the United Nations' Intergovernmental Panel on Climate Change, shifting from meat and animal products to a plant-based diet can significantly reduce an individual's carbon footprint and mitigate climate change.

Food production is responsible for up to 30% of total greenhouse gas emissions, with animal products accounting for about three-quarters of these emissions. Beef, in particular, has an outsized impact, contributing the most global greenhouse gas emissions among all meat and dairy products. This is because farming livestock uses 83% of all farmland, and an estimated 33% of all croplands are used to grow livestock feed.

By contrast, plant-based diets focused on fruits, vegetables, grains, and beans help protect the planet. A global shift to a plant-based diet could reduce mortality and greenhouse gases caused by food production by 10% and 70% respectively by 2050. This is because vegan and vegetarian diets have been associated with the greatest reductions in greenhouse gas emissions. For example, one study found that swapping beef for beans could help a country like the United States reach its greenhouse gas reduction targets.

In addition to reducing emissions, a vegan diet can also help fight climate change by preserving water and land resources. Agriculture accounts for about 70% of freshwater use, with meat and dairy products leading the way in agricultural water use. Producing just one pound of beef requires 1,800 gallons of water. Similarly, animal agriculture occupies a large amount of land, with 40% of Earth's ice-free landmass used for agriculture.

Overall, a vegan diet can help fight climate change by reducing greenhouse gas emissions, preserving water and land resources, and lowering an individual's carbon footprint.

It can help reduce water scarcity

Water scarcity is a pressing issue, with agriculture accounting for about 70% of freshwater use globally. This makes it the world's largest water-consuming sector. Meat and dairy products are the most significant contributors to this, with animal agriculture requiring more water than plant crops.

The water footprint of beef is particularly high, with one source stating that producing just one pound of beef requires 1,800 gallons of water. This is the equivalent of about 100 showers for the average American! In contrast, plant-based foods have a much lower water footprint. For example, producing a pound of wheat requires only 550 gallons of water, and other crops such as potatoes and rice have even lower water requirements.

A shift towards veganism could, therefore, significantly reduce water consumption. It is estimated that if the United States cut its consumption of animal products by half, its food production would require 37% less water. This reduction in water usage would not only help to alleviate water scarcity but also have a positive impact on the environment, as less water is diverted from natural habitats and ecosystems.

In addition to reducing water consumption, a vegan diet can also help to address the issue of water pollution. Animal agriculture is a significant contributor to water pollution, as large amounts of water are required to wash away the waste produced by factory farms. The waste often contains high levels of nutrients and bacteria, which can contaminate water sources and harm aquatic ecosystems.

By reducing the demand for animal products, veganism can help to decrease water pollution and preserve water sources for future generations.
