Utilization of waste as an effort to reduce global warming

Wednesday Nov 20, 2013

globalThe term waste would have been familiar to the ear. If you hear the term waste, certainly comes to mind is a pile of waste that cause the smell was overpowering stench. Waste is defined as unwanted waste material after the end process. Trash is a chemical, energy or beings that do not have a use value and tends to destroy. Waste is a man-made concept, in the processes of nature there is no waste, only products that are not moving.

Trash can be at any phase of matter that is solid phase, liquid, or gas. When released in two phases, namely liquid and gas, especially gas, can be regarded as waste emissions. Usual emissions associated with pollution. When the waste into the environment (water, air and into the ground) it will decrease the quality of the environment. Event is the inclusion of waste into the environment is known as environmental pollution events.

Based on the source waste bins are divided into natural, human waste, trash consumption, nuclear waste, industrial waste, and waste mining. While by its nature is divided into two bins :
1 ) organic waste or waste that can be parsed ( degradable ) for example, leaves, vegetables , kitchen scraps , etc. ,
2 ) inorganic waste or waste that is not biodegradable ( undegradable ) for example plastic , bottles , cans etc. .

Acid Rain: Causes, Impacts and Prevention

Thursday Oct 3, 2013

Acid rain is the rain process in which the pH value or potential of Hydrogen from rain water that fell below the 6 or about 5.6. PH value is below the normal pH of the 7. Means rainwater that fell to earth as acid mixed with certain compounds that dissolve in rain water causing increased acidity value. Carbon dioxide-soluble compounds with weakly acidic rainwater.

This condition is very beneficial for dissolving the minerals in the soil that are needed by plants and animals. However, the greater the acidity of the rain will cause adverse effects to the environment. Acid rain become a serious environmental problem, the higher acidity of rainwater, the greater the effect on the environment.

The cause of acid rain

Acid rain can occur naturally or by man-made actions, the following describes some of the causes of acid rain in general:

Source of Soil Contamination

Thursday Sep 12, 2013

soilSources of soil pollution, soil pollution is not much different or can be said to have a close relationship with air pollution and water pollution, the sources of air pollutants and sources of water pollution in general are also a source of soil contaminants. For example, carbon oxide gases, nitrogen oxides, sulfur oxides into the air pollutants that dissolve in rain water and fell to the ground can cause acid rain causing pollution in the soil.

Ground water containing pollutants such as contaminated radioactive substances, heavy metals in industrial waste, household waste, hospital waste, the remnants of fertilizers and pesticides from agricultural areas, waste detergent, eventually also can cause pollution in the area where the ground water surface or ground water surface area through which the contaminated soil.

Then ground source pollutants can be grouped also be a source of pollutants coming from, household waste, market waste, hospital waste, erupting volcano / motor vehicle and industrial waste.

Effects of Forests on Environmental

Thursday Aug 29, 2013


Forests also give effect to other natural resources, this influence through three interrelated environmental factors, like climate, soil, and water supply for the various areas, for example, agricultural areas. Interest questions concerning the causal relationship between climate and forests. Why the growth of trees in areas that lack very little rain? Does less rainfall, causing the growth of small trees? Or is it vice versa?

From the comparison of the state of the forests have been cut down by the still intact can be concluded, that the forest does have an influence on the local climate conditions (microclimate). In the logged forest rainfall is less. There information about forests and shrub influences on the microclimate as follows.

Trees can reduce wind velocity, so consequently reduce water evaporation (evaporation) of plants protected by it. If the plant crop, then clearly this plant will have more water supplies, due to less evaporation, so that the growth of both. Of course the influence of forests to agricultural crops is different from one species to another; also different according to the different circumstances and situations.
