Human impact on earth

University of Leicester The significant scale of human impact on our planet has changed the course of Earth history, an international team of scientists led by the University of Leicester has suggested. Rapid changes to the planet include acceleration of rates of erosion and sedimentation; large-scale chemical perturbations to the cycles of carbon, nitrogen, phosphorus and other elements; the inception of significant change to global climate and sea level; and biotic changes including unprecedented levels of species invasions across the Earth. This is a summary of the findings and interim recommendations of the international working group that has been studying the Anthropocene since Initially reported to the International Geological Congress at Cape Town, South Africa, the findings and recommendations have just been published online in the journal Anthropocene.

Based on the present growth rate of 1. Because population growth can not continue indefinitely, society can either voluntarily control its numbers or let natural forces such as disease, malnutrition, and other disasters limit human numbers Pimentel et al.

Hazy, yellow-brown blanket of smog found over cities that is formed with the pep of sunlight, contains ozone near the Earth's surface, and can damage lungs and plants. Volume of water that flows past a specific point per unit of time. Next Generation Science Standards Earth Science Disciplinary Core Idea 3C: Human Impacts on Earth Systems. In this video Paul Andersen explains how humans are impacting the Earth through farming, mining, pollution and climate change.

Increasing human numbers, especially in urban areas, and increasing food, water, air, and soil pollution by pathogenic organisms and chemicals, are causing a rapid increase in the prevalence of disease and number of human deaths WHO,; Murray and Lopez, ; Pimentel et al.

An estimated 40, children die each day due to malnutrition and other diseases WHO, In addition, we suggest appropriate policies and technologies that would improve the Human impact on earth of living and quality of life worldwide.

As human populations continue to expand and finite resources are divided among increasing numbers of people, it will become more and more difficult to maintain prosperity and a quality of life, and personal freedoms will decline UNFPA, ; RS and NAS, ; Rees, During recent decades there has been a dramatic worldwide population increase.

India has nearly 1 billion people living on approximately one-third of the land of either the United States or China.

Together, China and India constitute more than one-third of the total world population. Given the steady decline in per capita resources, it is unlikely that India, China, and the world population in total will double. In addition to limitations due to population increases, high per capita consumption levels in the United States and other developed nations also put pressure on natural resources.

For example, each American consumes about times more goods and services than the average Chinese citizen PRB, This does not imply that both developed and developing countries can not use their resources more efficiently than they are at present through the implementation of appropriate policies and technologies.

Accelerated declines in the U. Measurable shortages of fertile land, water, and fossil energy now exist in many regions of the world Worldwatch Institute, ; WRI, ; WRI, Globally, the annual loss of land to urbanization and highways ranges from 10 to 35 million hectares per year, with half of this lost land coming from cropland Doeoes, Inwhen the world population numbered about 3 billion, approximately 0.

The average per capita world cropland now is only 0. This shortage of productive cropland is one underlying cause of the current worldwide food shortages and poverty Leach, ; Pimentel and Pimentel, For example, in China, the amount of available cropland is only 0.

This minute amount of arable land forces the Chinese people to consume primarily a vegetarian diet Table 2. By all measurements, the Chinese have reached or exceeded the limits of their agricultural system Brown, Next Generation Science Standards Earth Science Disciplinary Core Idea 3C: Human Impacts on Earth Systems.
