Did you know that the global population is set to increase from 7.8 billion to 9.7 billion by 2050? Right now, we are consuming resources faster than the Earth can replenish them. By 2050, we would need three planets’ worth of resources to meet our current needs!
The livestock industry plays a key role in supplying these needs, but also has a harmful impact on the environment. It makes up to 51% of greenhouse gases globally in the form of carbon dioxide (CO2), nitrous oxide, ammonia and methane. These are all significant contributors to global warming. These gases are not only naturally emitted from the animals themselves, but also through the manure they produce, the fuel burned to transport the meat, electricity for storage and to gases used to cook them. All these results in more emissions than cars, planes and all other forms of transport combined.
Additionally, the livestock industry requires extensive use of land, with up to a third of the world’s total land is used up for rearing livestock. The limited availability of land results in forests being cleared to be converted to pastures. This, along with overgrazing by livestock animal leads to soil erosion and desertification. The waste produced by the industry often ends up in our water, polluting and harming both aquatic and human life.
With demand for meat expected to more than double by 2050, these negative impacts will only worsen.
By moving away from a meat-based diet to a vegetarian one, we could great reduce the stress on our planet’s environment and resources. It takes less land and resources to grow food for vegetarian diet, up to 20 times less than the livestock industry, meaning more people could be fed with far less land and resources consumed. As it takes less land to grow edible vegetables and fruits, this greatly reduces the need for land clearing and thus, reduce soil erosion and halt desertification.
A vegetarian diet also produces far less greenhouse gases. According to a study by Oxford University, vegetarians produce 2 times less greenhouse gases compared to people who consume meat. The same study also found that vegetarians generate only 3.8kg of carbon dioxide daily, while people who consume meat generate 7.2kg daily. Going vegetarian makes a big difference to the environment.
Adopting a vegetarian diet means we could dramatically reduce the amount of land, water and oil resources we consume and the amount of pollution we might cause. It is a snowball effect that begins with what we decide to put on our plate.
