A healthy diet, good sanitation, exercise, fresh air, a sense of purpose and loving relationships are key for healthy humans.
Today, the world population uses approximately 50 percent of total habitable land for agriculture, yet with our lifestyles and ways of growing our food we are running out of healthy food sources rapidly, including the fish in our oceans and enough clean drinking water for everyone.
A healthy human body needs the right blend of 7 essential nutrients - Water, Carbohydrates, Protein-Amino acids, Fat, Vitamins, Minerals, Omega-3 fatty acids. Livestock takes up nearly 80% of global agricultural land, yet produces less than 20% of the world’s supply of calories.
As we get richer, our diets tend to diversify and per capita meat consumption rises; economic development unfortunately exerts an increasing impact on land resources. If we want per capita meat consumption to be able to rise sustainably at lower incomes, per capita meat consumption at high incomes must decrease.
