nowadays, many people live in a home with small or no outdoor areas. is it positive or negative development?

Nowadays, majority of people live in accommodation with small or no outdoor areas in urban areas, with the increasing population rate in the world. Although there are numerous disadvantages of this, it is positive development, I think. From one angle, living in a home with the little space may lead several problems. Firstly, it is hard for people who live in such areas growing plants or keep pets because there is not enough place for crops and animals. This may cause those people who like plants and pets to feel bored on their holidays. Secondly, it can cause health problems of those people, because they cannot do tasks which are useful for health in home without outdoor areas. As a result, health problems such as obesity may arise with them in my view. From another angle, one advantage of living in such places is that the government can build more accommodation in comparison to other types in small areas. So providing with home more people cannot be impossible. As a result, deforestation and building many houses is not necessary and effects of people to the environment may decrease. Japan, for example, most people live in a home with small or no outdoor areas. That is why government do not need cut down forest and build many homes owing to providing with house their people. Similarly, it is more economical live these areas, because pay much money for tax is not required thanks to cost of tax is low. To conclude, despite small or no outdoor areas may lead few problems in modern life, but it makes chance for many people live in urban areas and this is positive progress, I think.
