Some people think that parents should teach their children how to be good members of society. Others, however, believe that school is the best place to learn this. Discuss both views and give your own opinion

In some countries, it is becoming increasingly common for people to 
follow a vegetarian diet. Do the advantages of this outweigh the 
disadvantages?
There is an increasing trend for people in some nations to have vegetarian 
foods for their meals. This essay thinks that the benefits do not outweigh 
the drawbacks because although vegetarian diets can reduce carbon 
footprints, consuming vegetables only may lead to nutritional deficiencies. 
The main advantage of having a vegetarian diet is that carbon emissions 
can be reduced. Animal agriculture accounts for a significant portion of 
carbon footprints because animal feed has to be transported a long way to 
farmers, and animals release a large amount of carbon dioxide after they 
eat the feed. For example, a research by the University of Australia found 
that around 35% of carbon emissions around the world is from animal 
agriculture, and if everyone eats vegetables, carbon footprint in animal 
agriculture can be reduced by one third. However, this essay argues that 
people may not be able to get nutrients which is available only in meats if 
they solely consume vegetables. 
One disadvantage is that vegetarian diets may cause nutritional 
deficiencies. That is because vegetables do not contain nutrients or 
minerals that are available in meats, and in the long run vegetarian may 
suffer from diseases caused by nutritional deficiencies. For instance, meats

provide minerals such as iron to strengthen the red blood cells. If people 
do not gain enough iron, their immune systems will be weakened, and in 
most serious case, brain functions will be impaired. Therefore, this essay 
believes that a balanced diet with meats and vegetables should be 
followed. 
In conclusion, although eating vegetables solely can reduce carbon 
emissions, unbalanced diets with only vegetables may lead to nutritional 
deficiency.
