The Ecological Imbalance

Any thing or factor that upsets the balance of nature leads to ecological imbalance.There are several factors contributing to this.These are interacting factors. On the top is the interaction between inorganic and organic factors, also called abiotic and biotic factors: Interaction between living and nonliving.
Among the living beings are producers(plants), decomposers(bacteria etc) and consumers(humans etc).Then there are food chains and food webs that constitute a relationship among the living beings.When they die, they are decomposed into nonliving matter. In the entire gamut of things man alone is capable of manipulating the environment by certain activities of which he is capable.Man's greed and propensity for sexual life lead to depletion of natural resources and these two are the most potent factors for ecological imbalance. Most of the times we dont even realise how a small action done on our part can lead to environmental imbalance and can cause many things that can actually destroy the balance that the nature restores by itself.
for eg. Using a plastic carry bag is such a normal and usuall thing for us that it has become an inherant part in our life but we never realise that this small action of ours can lead to the plastic bag being right there in our environment for something around 10000 - 15000 years. so what we are in a sense crearting is a world full of wastes and full of hazardous things.

Electronic waste the present scenario

There is an estimate that the total obsolete computers originating from government offices, business houses, industries and household is of the order of 2 million nos. Manufactures and assemblers in a single calendar year, estimated to produce around 1200 tons of electronic scrap. It should be noted that obsolence rate of personal computers (PC) is one in every two years. The consumers finds it convenient to buy a new computer rather than upgrade the old one due to the changing configuration, technology and the attractive offers of the manufacturers. Due to the lack of governmental legislations on e-waste, standards for disposal, proper mechanism for handling these toxic hi-tech products, mostly end up in landfills or partly recycled in a unhygienic conditions and partly thrown into waste streams. Computer waste is generated from the individual households; the government, public and private sectors; computer retailers; manufacturers; foreign embassies; secondary markets of old PCs. Of these, the biggest source of PC scrap are foreign countries that export huge computer waste in the form of reusable components.

Electronic waste or e-waste is one of the rapidly growing environmental problems of the world. In India, the electronic waste management assumes greater significance not only due to the generation of our own waste but also dumping of e-waste particularly computer waste from the developed countries.

With extensively using computers and electronic equipments and people dumping old electronic goods for new ones, the amount of E-Waste generated has been steadily increasing. At present Bangalore alone generates about 8000 tonnes of computer waste annually and in the absence of proper disposal, they find their way to scrap dealers.

Electronic Waste - the next big thing (threat i suppose)

hi all,
we must've talked and heard a lot about the tons of plastic waste that we create every day, we are still not concerned about that to a great extent. The hazards of the plastic waste is not even known to everyone despite we being talking about it from such a long time. I was recently going through the web when i read about the hazards of the electronic waste that is affecting life of people seriously. People in the USA have started getting worried about it but the here in India not many people are even aware of this thong. Wipro being the only company in this field. we need to take a serious look into this and find out the ways to reduce it or dispose it properly.
