Everyone should become a vegetarian because they do not need to eat meat to have a healthy diet. Do you agree or disagree?

There are 2 body paragraphs in my essay. Please help me correct them!! Thank you so much.

The primary reason why people should become vegetarians is that a plant-based diet might do wonders for your health. If people have dietary meals with solely fruits and vegetables, they are bound to less suffer from some chronic diseases such as heart disease, obesity, hypertension, diabetes and some types of cancer. They meet the requirement of vitamins, stimulate the digestive system by intaking plant foods which are high in fiber. In contrast, a person would face a deterioration in health status if he lived on meat products which are rich in cholesterol and saturated fat. For example, meat-eaters stand a higher chance of gaining weight, increasing blood pressure and risking their health.

Another significant reason is that if people eat healthy vegetarian diets, the environment will be more ecologically sustainable. Firstly, people have to grow more plants to produce more vegetables and fruits to consume. The vegetarian planting can considerably reduce the negative effects of climate change by generating a great deal of oxygen. Secondly, the more people becoming vegetarians, the fewer animals killed for meat-based meals. It is such an inhumane activity that people have the right to deprive the animals' existence.
