Aging populations are the most significant factor in population change in MEDCs. How valid is this view? (30) Throughout the world‚ MEDCs face the issue of an aging population and population change. This is due to the stage in which that county is according to the demographic transition model which indicates that as birth rates decline and death rate remain stagnant‚ an aging population is created. In the UK for example the baby boom of the 1950s due to increased confidence and the feeling of

The population of the world is slowly increasing. As this happens‚ we need to take great caution in making sure we don’t harm the environment. If we don’t be careful then it could lead to disastrous effects for us and nature. As cities grow larger and larger the natural land around them is being turned into homes and office buildings. We need to set up more parks inside cities to allow for the large amount of urbanization. These parks help to beautify the city while helping to preserve our environment

Against Population Control “Human population control is the practice of artificially altering the rate of growth of a human population. Historically‚ human population control has been implemented by limiting the population’s birth rate‚ usually by government mandate‚ and has been undertaken as a response to factors including high or increasing levels of poverty‚ environmental concerns‚ religious reasons‚ and overpopulation. While population control can involve measures that improve people’s lives
