Some people decide not to eat meat or fish, because they believe that a vegetarian diet is better for their health and also good for the world. In this essay, I will discuss this view and give my opinion.
Firstly, many people believe that a vegetarian diet is healthier. Vegetables, fruits, beans and whole grains contain a lot of vitamins, minerals and fibre, and they have less fat than meat. Some studies show that vegetarians have a lower risk of heart disease, high blood pressure and some types of cancer. In addition, people who eat less red meat and processed meat, such as sausages and bacon, may live longer.
Secondly, a vegetarian diet can be good for the world. Raising animals for food needs a lot of land, water and food for the animals. Many forests are cut down to make space for farms, and cows produce a lot of methane, which is a greenhouse gas that causes global warming. Moreover, catching too many fish is reducing the number of fish in the oceans. If more people stop eating meat and fish, the environment will be better protected.
However, a vegetarian diet also has some problems. Meat and fish are good sources of protein, iron and vitamin B12, so vegetarians must plan their diet carefully to get enough nutrients. In addition, in some poor countries, people cannot choose their food freely.
In my opinion, it is not necessary for everyone to become vegetarian, but people should eat less meat and more vegetables. This is good for both their health and the environment.
In conclusion, I agree that not eating meat and fish can be good for people's health and the world, but I think eating less meat is a more realistic choice for most people.
