When talking about pollution in general people usually refer to air and water pollution neglecting the global threat of noise pollution. They seem to forget or are not aware of the fact that noise pollution is disturbing life of all biota present in ecosystem.

***Generically, the term 'noise' is used to refer to any unwanted sound. This may range from the sound created when you hammer a nail into a wall, to the sound created by an aircraft overflying your house. Noise pollution describes any sound created by people, animals, and machines that disturbs the environment.

Urbanization, economic growth and motorized transport are some of the driving forces for environmental noise exposure and health effects. Environmental noise is defined as noise emitted from all sources except industrial workplaces.

The response of the human ear to sound depends both on the sound frequency (measure in Hertz, Hz) and sound pressure, measure in decibels (dB). The WHO guidelines for

In the course of growing concerns about unstable oil supplies and the impact of fossil fuels on global warming, bio fuels are receiving increased attention. Putting ethanol instead of gasoline in your tank saves oil and is probably no worse for the environment than burning gasoline.

Bio fuels, which are made from corn, palm oil, sugar cane and other agricultural products, have been seen by many as a cleaner and cheaper way to meet the world's soaring energy needs than with greenhouse-gas emitting fossil fuels. Ethanol is considered as major bio fuel.

Ethanol is an alcohol-based fuel made by fermenting and distilling crops that have been broken down into simple sugars. Ethanol can be used as a fuel for non-diesel engines ( spark ignition ) or as an additive to gasoline engines In the U.S., ethanol is mostly manufactured from starchy crops like corn.

There are two types of ethanol fuel that are commonly referred to- e85 and e10. E85 is a blend of 85 percent ethanol and 15

November 13-19 is the National Geographic Society's Geography Awareness Week. This year's theme is The Adventure in Your Community. Geography is all around us and varies from region to region in the Pakistan. Did you know that geography and weather are very closely linked? Mountains and Rivers can influence an area's climate by affecting both temperature and precipitation. As elevation increases, the Atmosphere becomes less dense. When it is less dense, its ability to absorb and hold thermal energy is reduced and temperature gets lower. Rivers and seas also help the climate in cooling and absorption of heat waves. Climate change is likely to have a profound effect on human societies around the World. Over the past decades much effort has concentrated on the physical science behind climate change. With the general acceptance of anthropogenic climate change, emphasis has recently shifted towards climate change impacts, adaptation and mitigation.Explore some of the connections below.

According to the U.N. FAO, 2.2% or about 1,687,000 ha of Pakistan is forested, according to FAO. Pakistan had 340,000 ha of planted forest.

Change in Forest Cover: Between 1990 and 2010, Pakistan lost an average of 42,000 ha or 1.66% per year. In total, between 1990 and 2010, Pakistan lost 33.2% of its forest cover or around 840,000 ha.

Pakistan's forests contain 213 million metric tons of carbon in living forest biomass. Biodiversity and Protected Areas: Pakistan has some 1027 known species of amphibians, birds, mammals and reptiles according to figures from the World Conservation Monitoring Centre. Of these, 3.5% are endemic, meaning they exist in no other country, and 5.5% are threatened. Pakistan is home to at least 4950 species of vascular plants, of which 7.5% are endemic. 4.0% of Pakistan is protected under IUCN categories I-V.

Khurshid Ahmed, an environmentalist from Peshawar University, says most of the logs illegally cut from Pakistan's forests have been

With barely a month left for the global climate change negotiations in Durban, China is been hosting the ninth BASIC (Brazil, South Africa, India and China) ministerial meet Oct 31-Nov 1. Representatives of the countries of Group 77, island countries and the Arab League also attended the meeting.

A meeting of experts will be held alongside this meeting to carve out a strategy for the United Nations Framework Convention on Climate Change (UNFCCC) Conference of Parties 17 (COP 17) to be held in Durban, South Africa, Nov 28-Dec 9. Politics of Green and climate change issues are been discussing in this Beijing meeting, Forest as major source of climate play important role in climate change and have great significance.

Forests have four major roles in climate change: they currently contribute about one-sixth of global carbon emissions when cleared, overused or degraded; they react sensitively to a changing climate; when managed sustainably, they produce wood fuels as a benign

As earth is considered to be 4600 million years old and we as major living creatures harming it badly by different types of pollution production. The Earth's temperature is rising. We can argue about whether it is a short-term or long-term trend, or whether it is natural variation or man-induced, but it is warming. Its greatness of nature which, correct our mistakes by itself, but we don't give too much harm that it in return give us just punishment (as few we are facing in form of floods, lava eruption, drought and famines etc.) But now it's our duty to pay something to cure our mother earth, a normal person helps it by just planting a tree in its surrounding because trees are co2 absorber. Scientist and other experts of their own field working much more to form the substitute of trees which can sink co2 an in return decrease global warming and it drastic effects.

The idea for formation of synthetic tress was given by many geoscientist and environmental experts but mainly
