In the wild, rampant population growth of prey species often causes growth in the populations of predators. The environmental impact of transport is significant because transport is a major user of energy, and burns most of the world's petroleum.This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide. Introduction. Living things live in their environment. Regarding the human population, end-targets for an optimum population include ecological sustainability, economic output, and philosophical or ethical ends-in-themselves. As the population gets older it gets more affluent too, thereby demanding higher living standards to satisfy their ‘wants’. They constantly interact with it and adapt themselves to conditions in their environment.

Some commentators disagree with the concept of "optimum population", believing that the human population will always, in the long-term, be able to adapt to the requirements of a larger population.[4]. The trajectory undergone by such a population has been called 'overshoot-and-collapse'. This lessens the risk of environmental impacts and enhances the potential for societal resilience to climate change, water scarcity, food insecurity, the loss of biological diversity, and related threats. The term human overpopulation also refers to the relationship between the entire human population and its environment: the Earth, or to smaller geographical areas such as countries. An Increased population intensifies impact on the environment as more individuals take up space, use resources, and generate waste. After the prey population crashes, the overpopulation of predators causes the entire … The current population of the Earth is over 7.6 billion people and growing. Human beings get all the basic needs such as shelter, food, clothing etc. Some deep ecologists, such as the radical thinker and polemicist Pentti Linkola, see human overpopulation as a threat to the entire biosphere.
