Human and Wastes- View Slides and Video clips
Waste suppose the biggest problem and challenge for human, however for years, its managment and disposal has been given less attention. The problem of waste is closely linked with poluttants of air, water and soil that has caused so much damage to land and space we even pay too much attention to instead of waste. The exclusion from production of the external diseconomies of solid waste has loaded the land with mountains of garbage which impose unrecognized and unestimated costs on the community at large. The waste are by- product of the way human want to live and the things they want to do. This make it quite logical to be something we look at after problems of our new tendency, industrial work, this is also perhap a misleading objective because disposal issue should be given a thaught prior all these work. Have a look at the slides. Unfortunately modern man great contibution to polu tion is increasingly taking place on land- in urban , industrial , holiday areas, it all about problem of mounting load of solid wasts that must be disposed off. So is it in agriculture , the problem of polution include waste.Therefore, all the modern man metamorphoses - as industrial worker, city dweler,recreational seaker, as farmer- leave behind a thickness trail of soslid waste - not only this all the war we are fighting leave behind unimaginable loads of HAZARDOUS WASTE whose chemical reaction and transport process is even hard for us to know , because the knowledge is not there. Likewise the problem of strip mining and quarying after the extration of natural resouces leave lands with so much contamination from waste rock and mill trailing - leaving special problem, where acid steps out into undergorud wates. The land above abandoneed mines subsides leaving houses balancing on the edge of hundred -foot crates,waste of all mine dumps frequently catch fire and go on burining with a slow and enourmous expenses obstinacy. Land itself cover only 29 percent of the planet- And if care is not taken we can end loosing large part of this to environmental problem which is largely a consequence of human waste and human reckless activities. However the disposal of waste itself depends on the nature of the waste - cities in developed countries manage to get rid of human wastes through their sewage systems without reverting to the horors of 19th century sanitation. It is also true that a lot of other organic wastes from households - The outer leaves of lettuse, pot scouring, apple skins are now under better control in the cities than in the past, when they ued to be chucked on the town dumped or droped fron second floor window on the street below.he...he.., there to be eaten by disease - carrying rats or scavenging dogs - The problem today is not much of risk of urban epidemic, compare with reuse, the society has to deal with municipal systems to dispose both urban and insdustrial waste from wet sewage which could also be a potential material for compost and manure, to discard engines, electronics items after their lifetime, broken garden furniture, usable scraps of metal to the extravagant trow-away materirials of the modern consumers. It is so obvious , even if you go to the supermarket, for some items they will load you with packaging explosion . Everywhere, what you see is can, bottle, discarded junks and the process of discarding keep rising. If this fast riding tide not bury society in the way in which the seven cities of Ur of the Chaldees have been burried under detritus of seven levels of civilization - we must solve this problem!!- Ironically the sad part of the story is that the air , the water , the soil , are one, they make up our ecosystem, we cannot control their transport process and we can`t predict what they will turn to over time, if they are too much contaminated -What do u think we can be done about waste:Reguarding , daily scraping, material management, packaging, cans what can we do ..Do you have mines or quarry, or or abandone mines in your area- what is the condiion of the land.D0 you have chemical or hazardous plants or dunmp in your areas, what is your community doing about this, what is the condision of the air, do they comply with the air quality dosage.what do u know about the disposal.Do you think killing weapons cause a lot of waste.do yiu think waste contribute to climate change.Do you company has collection facility for disposable gas or HFC refrigerator gas container.
