every plant-based meal raises life expectancy and quality
less meat- higher life expectancy? vegans live healthier and longer
Less meat – less CO2
To see how much our diets can contribute to protecting the climate, you just have to do some simple math. Animal products such as meat or milk meet 17% of the world population’s calorie requirements – but in order to do so, they need 77% of arable land globally: two thirds as grazing pastures and the rest for cultivating animal feed. This regrettable state of affairs could be changed if these areas were to be used for the cultivation of products (crops, cereals) which are consumed by humans directly.
When demand for animal products increases, the arable land has to be used very intensively; something which is only possible by using fertilizers and pesticides. The consequences of this are leaching, stress on local conditions, a reduction in biodiversity, and more water scarcity. Decreasing biodiversity in regions where most of the arable and grazing lands are used intensively also means that carbon dioxide stored in the ground is more likely to be released, thus constituting an additional burden for the climate.
The animals themselves also produce great quantities of CO2. Ruminant animals such as cattle also contribute to the greenhouse effect by emitting methane, the negative effect of which is 25 times that of carbon dioxide.
