Switching to a plant-based diet is an effective way for an individual to reduce their eco-footprint. Vegan diets can produce fewer greenhouse gas emissions than meat-based diets. A University of Chicago study found that the ‘typical’ US diet generates the equivalent of nearly 1.5 tonnes more carbon dioxide per person per year than a vegan diet. The livestock industry is responsible for 18% of global greenhouse gas emissions, more than the entire transport sector (which produces 13.5%), including aviation.
Plant-based diets only require around one third of the land and water needed to produce a typical Western diet. Farmed animals consume much more protein, water and calories than they produce, so far greater quantities of crops and water are needed to produce animal ‘products’ to feed humans than are needed to feed people direct on a plant-based diet. With water and land becoming scarcer globally, world hunger increasing and the planet’s population rising, it is much more sustainable to eat plant foods direct than use up precious resources feeding farmed animals. Farming animals and growing their feed also contributes to other environmental problems such as deforestation, water pollution and land degradation.
A balanced vegan diet (also referred to as a ‘plant-based diet’) meets many current healthy eating recommendations such as eating more fruit, vegetables and whole-grains and consuming less cholesterol and saturated fat. Balanced vegan diets are often rich in vitamins, antioxidants and fibre and can decrease the chances of suffering from diseases such as diabetes, heart disease, stroke and some cancers. Well-planned plant-based diets are suitable for all age groups and stages of life.
Many people become vegan through concern at the way farmed animals are treated. Some object to the unnecessary ‘use’ and killing of animals – unnecessary as we do not need animal products in order to feed or clothe ourselves.
Public awareness of the conditions of factory-farmed animals is gradually increasing and it is becoming more and more difficult to claim not to have at least some knowledge of the treatment they endure. Sentient, intelligent animals are often kept in cramped and filthy conditions where they cannot move around or perform their natural behaviours. At the same time, many suffer serious health problems and even death because they are selectively bred to grow or produce milk or eggs at a far greater rate than their bodies are capable of coping with.
Regardless of how they were raised, all animals farmed for food meet the same fate at the slaughterhouse. This includes the millions of calves and male chicks who are killed every year as ‘waste products’ of milk and egg production and the animals farmed for their milk and eggs who are killed at a fraction of their natural lifespan. Choosing a vegan diet is a daily demonstration of compassion for all these creatures.
