When animals are used, humans make choices for animals. Animals that are used are thus not free to make their own choices. Animal use is a violation of animal rights. Veganism is a way of living in which people do not use animals. It is thus an ethical choice to no longer violate animal rights by choosing a vegan way of live. By going vegan, you avoid a lot of animal suffering. Besides avoiding animal rights violations, veganism offers other benefits.
The livestock industry is responsible for a lot of damage to nature and the environment. This is because of greenhouse gas emissions, like methane and CO2, but also because of the pollution of air, water and soil with nitrogen. The industry is also responsible for large-scale deforestation. By going vegan, you no longer support this destructive industry.

Livestock farming uses more than 70% of all agricultural lands, but also supplies 17% of all food for humans. Eating animals is an inefficient way of food use. By choosing a plant-based diet you can contribute to diminishing world food inequalities.
