WHY COMPUTER GRAVEYARDS ARE IMPORTAN:-
COMPIUTER GRAVEYARD is one of the best ways for you to have a positive impact on the world in which we live. In comuter graveyard we recycle the old computers so it is important to both the natural environment and us. We must act fast as the amount of waste we create is increasing all the time.
The amount of rubbish we create is constantly increasing because:
Increasing wealth means that people are buying more computer products and ultimately creating more waste.
Increasing population means that there are more people on the planet to create waste. Environmental Importance
Recycling is very important as waste has a huge negative impact on the natural environment.
Harmful chemicals and greenhouse gasses are released from rubbish in landfill sites. Recycling helps to reduce the pollution caused by waste.
Habitat destruction and global warming are some the affects caused by deforestation. Recycling reduces the need for raw materials so that the rainforests can be preserved.
Huge amounts of energy are used when making products from raw materials. Recycling requires much less energy and therefore helps to preserve natural resources. Importance To People
Recycling is essential to cities around the world and to the people living in them.
No space for waste. Our landfill sites are filling up fast, by 2010, almost all landfills in the UK will be full.
Reduce financial expenditure in the economy. Making products from raw materials costs much more than if they were made from recycled products.
Preserve natural resources for future generations. Recycling reduces the need for raw materials; it also uses less energy, therefore preserving natural resources for the future.
