In many countries around the world, rural people are moving to cities, so the population in the countryside is decreasing. Do you think this is a positive or a negative development Negative > 1- cities are overcrowded - air pollution - incidence of disease ( mental problems disconnection from nature) 2-decreasing in agricultural products -lack of food -work force Over the last decades people tend to emigrate to cities due to many personal, economical , social , etc. reasons. This trend associated with overcrowding urban areas and inversely lack of population in rural region. I personally believe that definitely it has a negative effects on our environment and human health. To begin, the more the cities become overcrowded the more danger might enter people’s life.To have a better explanation, individuals abounded their farms to acquire better quality of life in convenience way, whereas nowadays the air pollution estimation states at the highest point which definitely have negative impacts on cardiovascular and respiratory systems even if we do not see psychological aspects of disconnection from nature. Moreover, in terms of hygiene, people are gathering in crowded public areas which increase the level of disease incidence as we all experienced this terrible condition in 2020 with covid.However, people in rural area could managed this disease more easily. To respond this tendency for living in urban areas, human must expand the cities and their infrastructures which contributed to destroy our environment. For instance, cutting trees to build new roads or extract more minors to contract new towers and apartments. Furthermore , threatening our natural habitants and biodiversities. In conclusion, emigration to cities from rural areas will disadvantage human health and surrounded environment. The se two factors always should be prioritized by governments to protect human generations.
