Global Warming and Human Population - 2270 Words

Essay on Deforestation in India Forest loss is directly-associated with human population growth. In 1921 human population was 25. 13 crores and forests cover was 104.05 million hectares. By 1989, forests cover reduced to 64.01 m ha, while human population in 1991 reached to 84.39 crores. Deforestation is due to diversion of forest land to agricultural land, river valley projects, roads, industiy and urbanization, transmission lines and activities like shifting cultivation, fuelwood and timber collection overgrazing fires and acid rains (vide Rana, 2006). Green wealth index (GWI) is an indicator of green wealth possessed by a State or Union Territory and Green Protection index (GP1) is a qualitative calculation of protection accorded†¦show more content†¦Most scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue to increase at an increasing rate. As a result, the world is getting warmer. The year 1990 was the hottest year in the last century. Together with 1991, the years of 1983, 1987, 1988 and 1989 have been measured to be the warmest six years in the last hundred years. The year 1991 was the second warmest year of the past century. The consequences of the rise in temperature is being felt all over the globe the findings of scientific research done in this field reveal that the temperature of the earth is likely to rise from 1.4 °C to 5.8 °C within a period of 100 years. Unfortunately, the imbalance which we have created between our life and earth is already showing the signs disasters in the form of flood, cyclones, landslides, tsunami, drought, etc. If the imbalance continues to rise, one day this will pose a question mark on the existence of this planet. Carbon dioxide (C02) which is an important constituent of environment is causing a warming effect on the earth’s surface. It increases the evaporation of water into the atmosphere. Since water vapour itself is a greenhouse gas, this causes still more warming. The warming causes more water vapour to be evaporated. The C02 level is expected to rise in future due to ongoing burning of fossil fuels and landuse change. The rate of rise will depend largely on uncertain economic,Show MoreRelatedGlobal Warming And Its Effects On Human Population1458 Words   |  6 Pagespast 100 years, the population of the world has gone from about 2 million people to just over 7 million people. With this drastic change in population in such a short period of time compared to the total age of the earth, problems are no doubtable going to arise. From the demand of the ever rising human population on the earth, food accessibility, depletion of natural resources, and an increase in global warming affects all have detrimental consequences on our human population and our own earth thatRead MoreThe Effects Of Global Warming On The World1235 Words   |  5 Pagesmay not be feeling the effects of global warming at the moment, but in time it will become a more widespread issue. The effects of global warming are hard to refute, and there is endless evidence of this growing problem in our world today. The continuation of global warming is a serious threat to everyone and everything on Earth. Global warming has been a problem for over a hundred years, and it continues to grow every day. The first evidence of global warming was discovered in 1859 by John TyndallRead MoreEssay on Global Warming: Polar Bears are Endangered769 Words   |  4 PagesEssay Title: Polar bears are endangered Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in NortheastRead MoreGlobal Warming Is A Natural Phenomenon1218 Words   |  5 PagesGlobal Warming Global warming is a natural phenomenon. People produce greenhouse gases, like carbon dioxide, by burning fossil minerals, cutting down trees and stripping the land, often referred to as deforestation. These greenhouse gases have high permeability to the visible light from the sun radiation, but they are highly absorbent to the long wave radiation that is reflected from the earth. These gases have especially strong absorption to the infrared from ground radiation. This phenomenonRead MoreHow Are We Affected by Global Warming and How Can We Stop It?1259 Words   |  6 PagesHow are we effected by global warming and how can we stop it? Global warming directly effects everyone and everything on Earth. The concentration of greenhouse gasses is climbing at an alarming rate. Many negative issues will take place if nothing is done stop the destruction of the Earths atmosphere. Humans, plants, and animals contribute to the cycle of life on earth. The extinction of plants and animals caused by global warming can lead to worldwide panic. The future flooding of the EarthRead MoreDifferent Arguments and Theories on Global Warming and Why to Take Action1464 Words   |  6 PagesTheories on Global Warming and Why to Take Action Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gasses, carbon dioxide and methane primarily, in the earths upper atmosphere directly caused by human burningRead MoreEssay on The Threat of Global Warming1667 Words   |  7 PagesThreat of Global Warming Through the eyes of most scientists, global warming is seen as a very serious and severe threat.

It wasn’t until fifty years later that the real causes and effects of global warming would be discovered. A British scientist by the name of Calendar correlated the 10% increase of atmospheric Carbon Dioxide between 1850 and 1940 with the observed warming of northern Europe and North AmericaRead MoreGlobal Warming And Its Health Impacts1573 Words   |  7 Pagestheory of global warming, the idea that the increasing amount of greenhouse gases in the atmosphere are trapping enormous amounts of heat and causing the earth to become warmer and warmer.

Although not everyone agrees on the cause of global w arming, something all can agree on is the fact that global warming is altering
