why is life on Hills tough❓❓
Answers
Explanation:
Higher up, the air is thinner, making it more difficult to get enough oxygen to allow your body to work hard. Steep slopes mean that growing food and building houses is also much more difficult. Travel is tough in the mountains.
new transport and communications technologies are bringing goods, services, infrastructure and information to even the most remote parts of the mountains. The mountain communities are being forced to integrate with the larger global society.[7]
The Food and Agriculture Organization estimated in their 2003 report that around 720 million, or 12% of the world population, live in the mountains. Of these, no more than 10% are in developed countries.[21] About half of all mountain people are in Asia, and there are large and rapidly growing populations in South and Central America. 70% live below 1,500 metres (4,900 ft), and less than 10% above 2,500 metres (8,200 ft). A very small number of people in the Himalayas and the Andes live permanently at elevations over 4,500 metres (14,800 ft).[17] The countries with the highest percentages of mountain people are Bhutan (89%), Rwanda (75%), Lesotho (73%), Armenia (70%), Guatemala (64%), Costa Rica (63%) and Yemen (61%).[22]
About 70% of the mountain population is rural and relies on farming, fishing and extraction from local forests.[23] The permanent mountain population also includes itinerant mineral prospectors, miners, loggers, construction workers and others who move from place to place. Better roads and vehicles may allow these people to live permanently in a mountain community some distance from where they work.[24] Forestry and traditional agriculture is declining in the mountain areas of Japan, Europe and the eastern United States as government subsidies are withdrawn.[25] Outside Europe and Japan the human population in mountains is rising as they are used as refuges, sources of minerals, for tourism, and for commercial forestry, farming and animal husbandry.[25] Colonization and immigration in the last 400 years have been causing steady population growth in formerly less populated mountain areas in Africa, Australia, New Zealand, South America, Canada and the Western United States.[25]
