Population growth and the environment

Population and environment relationship

Farming impacts A growing agricultural base to feed an expanding world population comes with its own complications. People in developed countries require substantially more resources to maintain their lifestyles compared with people in developing countries. It can result from a reduction in the carrying capacity of a region, such as reduced agricultural yield due to over farming or drought. Whether we have million people or one trillion, we still have only one planet, which has a finite level of resources. Perhaps we can feed 9. The IPAT equation, first devised in the s, is a way of determining environmental degradation based on a multiple of factors. For example, since conditions in the Middle East have seen population transfer also known as unplanned migration result in several million refugees fleeing countries including Syria, Iraq and Afghanistan. Population and Development Review, 21 4 , — Economic Affairs, 14 3 , 22— As well as bringing the link between population and environment to a wider audience, the IPAT equation encouraged people to see that environmental problems are caused by multiple factors that when combined produced a compounding effect. But with more generations living simultaneously, it puts our resources under pressure. Cited 9 March Global demographic trends and future carbon emissions. Developing countries should be supported by their more developed neighbours to reach their development goals in sustainable, practical ways. Population consumption While poverty and environmental degradation are closely interrelated, it is the unsustainable patterns of consumption and production, primarily in developed nations, that are of even greater concern.

Global demographic trends and future carbon emissions. Eurobarometer The condition of agricultural growth. According to the World Wildlife Fundthe land used and abandoned in the last 50 years globally may be equal to the amount of land used today. Our growth has been largely funded by rapidly depleting natural capital fossil fuels, minerals, groundwater, soil fertility, forests, fisheries and biodiversity rather than sustainable natural income.

Attitudes towards demographic trends and policy. The result of this depletion is deforestation and loss of biodiversity as humans strip the Earth of resources to accommodate rising population numbers. For most of our existence the human population has grown very slowly, kept in check by disease, climate fluctuations and other social factors.

The alternative is natural population growth control by mass starvation or disease, or control by crime and war.
