write a persuasive speech about (eating organic is good for your health) or (why airline tickets should be cheaper).

How your food is grown or raised can have a major impact on your mental and emotional health as well as the environment. Organic foods often have more beneficial nutrients, such as antioxidants, than their conventionally-grown counterparts and people with allergies to foods, chemicals, or preservatives often find their symptoms lessen or go away when they eat only organic foods.

Here are some key points for the first one:
-organic food is non GMO, meaning that the seeds and food itself has not been genetically modified to be bigger, pest resistant, etc
-there are few studies on the effects of pesticides on humans, there have been cases where pesticides had to be recalled
-levels of pesticides in your body go up when you eat non organic
-you know what you're putting in your body when you eat organic
