across the globe have already released over 5 million tonnes of toxic chemicals. These chemicals are production-related wastes and pollutants. Many industries also emit high amount of carbon dioxide gas. Other gaseous pollutants produced by industries across the globe include carbon monoxide‚ sulfur dioxide‚ chlorofluorocarbons (CFCs)‚ nitrogen oxides‚ etc. Organise a group activity to prepare a poster or model to list the most polluting industries in the world.

(NaturalNews) These days it seems you can`t even go two hours without seeing or hearing something about "being green‚" whether it`s an advertisement for an Earth-friendly product‚ news about an environmentally-sound investment‚ a report about a business or community that`s taking steps to be more eco-conscious‚ or just general advice on how to save the planet. "Going green" isn`t just the latest trend though; it`s something we all must do to conserve resources‚ combat climate change‚ and preserve

The main contribution of the air pollution is automobiles releasing the gases like carbon dioxide‚ unburned hydrocarbons etc. In order to avoid this type of gases by introducing this aqua silencer. It is fitted to the exhaust pipe of the engine‚ Sound produced under water is less hearable than it produced in atmosphere. This mainly because of

the Earth due to the use of fossil fuels and industrial processes that build up to the emission of greenhouse gasses‚ mostly carbon dioxide and methane (“Global Warming Threatens”). As energy from the sun strikes the surface of the earth‚ it turns into heat which‚ in turn‚ releases the heat as long-wave infrared radiation (Crowe). Gasses in the air‚ such as carbon dioxide‚ methane‚ nitrous oxide‚ chlorofluorocarbons‚ and water vapor‚ trap some of this radiation as it tries to make its way back out to

because plants absorb energy from the sun through the process of photosynthesis. When biomass is burned‚ this stored energy is released as heat. Burning biomass releases carbon dioxide. However‚ plants also take carbon dioxide out of the atmosphere and use it to grow their leaves‚ flowers‚ branches‚ and stems. That same carbon dioxide is returned to the air when the plants are burned. Many different kinds of biomass‚ such as wood chips‚ corn‚ and some types of garbage‚ are used to produce electricity

its generation and the surface is less than that of the surrounding and overlying rocks‚ the magma reaches the surface and erupts. Magmas of so-called andesitic and rhyolitic compositions also contain dissolved volatiles such as water‚ sulfur dioxide and carbon dioxide. Experiments have shown that the amount of a dissolved gas in magma (its solubility) at atmospheric pressure is zero‚ but rises with increasing pressure. For example‚ in an andesitic magma saturated with water and six kilometres below

global warming. [7] Smog is one of the forms of air pollution and one of its main components is sulfur dioxide. Although it causes acid rain it also is able to keep sunlight out of the Earth maintaining it cool. Thus reducing smog is actually helping even more the global warming as it lets more sunlight go through and gets trapped thanks to the pollution. [7] Some of the other greenhouse gases are carbon dioxide‚ methane‚ nitrous oxide‚ HFC’s‚ PFC’s and SF6. If these gases continue to rise‚ the ozone layer

pollution has a direct connection with urban environments all over the world. With an increase in industrialized countries ‚the of use of cars‚ factories and also the use of fuels such as fossil fuels that emit greenhouse gasses‚ like carbon dioxide and sulfur dioxide‚ into the air‚ there has been a definite rise in air pollution over the world (Mayer‚ 1999). There are many short term effects that air pollution causes to the urban areas and to the people who are living in those areas. The first short

CAUSES AND EFFECTS OF ENVIRONMENTAL PROBLEMS Environmental problem is the biggest menace to the human race on the planet nowadays. Although environmental problems cannot be coped hundred percent‚ we should contribute our efforts to minimize the environmental problems. This essay attempts to examine the causes and effects of environmental problems that happened in Malaysia. Firstly‚ let me look at deforestation that is the main cause of environmental problems. Deforestation is an activity of

Svante Arrhenius was the first scientist to describe the greenhouse effect‚ and is believed to have coined the term‚ predicting that rising levels of carbon dioxide (CO2) would cause the earth’s temperature to rise. The equation showing the effect of temperature on reaction rates is still called the Arrhenius Law. He was also a supporter of "racial biology"‚ part of the then-accepted science of eugenics.
