Resources disasters

Limited resources in economic growth is constrained. Resources for economic growth has played an important role.

Resources for the pessimists Thomas Malthus 1865. Stanley Jevons Britain would soon run out of coal, with disastrous results. H.G.wells The fixed supply of phosphorus (necessary of agriculture) as the factor limiting future growth.

The limits to growth Economic growth, fertility, mortality, prime minister available resources, renewable resources and pollution. Date from the period 1900-1970 to establish a baseline of past behavior and then used their model to forecast what would happen over the period 1970-2100. World population, food production per capita, per capita industrial production, renewable resources and the inability to represent trends on pollution

The limits to growth Food and industrial output per capita both peak around the year 2000, after which they fall due to shortages of nonrenewable resources. Population continues to rise for several decades after the peak of income because of demographic momentum, but sometime in the middle of the 21st century, the death rate is driven upward by lack of food and health services.

these doomsday scenarios have been utterly wrong. Improving agricultural productivity faster than population growth Underestimated the quantity of available coal, the ability of engineers to mine the coal and the role that oil would play in the 20th century. Food production, output per capita and stocks of nonrenewable resources thus far show no evidence of the ‘overshoot and collapse’ predictions of The Limits to Growth.

The story of Easter island Its closest inhabited neighbour is Pitcairn Island, 2,075 km (1,289 mi) to the west, with fewer than 100 inhabitants. Easter Island's latitude is similar to that of Caldera, Chile, and it lies 3,510 km (2,180 mi) west of continental Chile at its nearest point .

the island was settled by about 40 Polynesian migrants around a. d 400 the island was settled by about 40 Polynesian migrants around a.d 400. at the time of its settlement, Easter Island was covered with a forest of palm trees.

Easter Island they cut down trees to build boasts, caught fish in the rich waters off the island, hunted birds that lived in the forest, and farmed the fertile soil. with food so abundant, the population naturally grew. at its peek, from A.D 1100 to 1400, the island supported a population of 10,000. During this period, the island’s society was wealthy enough to maintain a special class of artisans, who carved the giant statues that to this day ring the island.

but, the rise in population was more than the island’s resources could sustain. trees were cut down faster than they could regenerate, and the size of the forest declined. The birds that the settlers had hunted disappeared, and eventually no good trees were left for making fishing boats.

Easter Island the Europeans who arrived at the island in 1722 found a population of only 3,000. a level of civilization far below that had been required to build the giant statues. the island was devoid of tree, and no one could figure out how, without wooden rollers, the giant statues could have been moved to their location. There are no trees.

conclusion the development of sustainable resources. development of technology Or… there is another way…

we should go out the earth and acquire the resources which is from the another planet.
