     Today I listened to "Veganism Even for Christmas?". I will make sentences using these words.

     Because of increasing deforestation, we have many environmental problems such as water shortage and increasing emission of greenhouse gas. So we have to cut back on water consumption. If many people vegan, it is ethically good and contribute to environmental problems.
