Correlation between the PLANTING OF TREES & reduce GLOBAL WARMING.

"Planting trees is an initial effort to reduce global warming"

Global warming is the increase in average air temperatures across the earth's surface. Air temperature rise occurred because more and more greenhouse gases in the earth's atmosphere. 

These gases include water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4), along with other gases surrounding the earth which is called the air. 

These gases have a greenhouse effect, so that sunlight can enter through the glass, but heat from the greenhouse can not go out because it was blocked by glass, so that the air inside the greenhouse gradually became hotter. 

Things like this do farmers in temperate regions to enhance and maintain stable temperatures in the region's agriculture. 

Similarly, the greenhouse gases in the earth's atmosphere. Sunlight is able to break through the layer of gas that reaches the earth's surface. Some light is absorbed by the earth, other re-emitted into the atmosphere (air) in the form of heat. 

This heat will be absorbed by greenhouse gases, then re-emitted in all directions directions, including most of the direction of the earth. Heat emitted back toward Earth that causes the air temperature at Earth's surface would be higher. 

Indeed the existence of greenhouse gases is very rudimentary so that the earth could be inhabited by living creatures, including humans, because if these gases did not exist then the earth's surface temperature will be very cold and did not allow living things to survive. 

Increasing the concentration (amount) of greenhouse gases in the atmosphere by itself will increase the amount of heat trapped in the earth's surface air layer. In the long term this is what causes global warming. 

Among greenhouse gases, the amount of carbon dioxide gas is increasing significantly, activity associated with an increased use of fossil fuels (gas, oil and coal) for various purposes such as transportation, industry and households, from pre-industrial era to era today's modern. 

The amount of methane gas also increased due to agricultural activities, but far fewer in number than carbon dioxide gas. 

Any burning of fossil fuels will release CO2 into the air as the rest of the combustion in a comparable amount. 

Monitoring at Mauna Loa Observatory, Hawaii, consistently increasing CO2 concentration of about 318 ppm in 1957 to about 387 ppm in the year 2010. 

Meanwhile, the intergovernmental panel of experts on climate change (IPCC) revealed that the Earth's surface temperature increased 0.6 degrees Celsius from year 1861 till the year 2001, and currently estimated Earth's surface temperature increased about 0.74 degrees Celsius. 

Negative impacts of global warming has been voiced many circles since several decades ago, but the world community, especially among the industry realized in recent years after the polar ice began to melt. 

It was feared that melting ice will raise sea level, which could drown some islands and coastal cities, and all community activities in coastal areas. 

Another impact of the interruption in the pattern of global warming climate. Irregular weather patterns make agricultural cropping patterns become chaotic, and even can result in crop failure could lead to starvation for humans. 

For example, during the rainy season in Indonesia was known in the period September to February, and the dry season (heat) in March until August. With this pattern, usually farmers plant rice in December (peak season) and plans to harvest in March or April (early dry season). 

Because of climate change, the rainy season lasts until March, then the rice will be destroyed and can not be harvested. 

In addition, rising temperatures could lead to new diseases are difficult to treat, because it had not done the research. 

Experts estimate when the air temperature increased by two degrees Celsius, the earth's ecosystem changes that occur can not be recovered (ir-reversible), many creatures will become extinct. 

Therefore, to avoid a catastrophe because of the temperature rise of the world's nations agreed to reduce carbon emissions into the air starting in 2020. 

There are several ways to reduce the amount of CO2 in the air, among others, reduce use of fossil fuels and planting trees / plants / plants to absorb CO2 from the air. 

Reduce use of fossil fuels can be done with efficiency and energy use or use other energy sources like nuclear energy, solar, hydropower and others. 

Meanwhile, the absorption of CO2 from the air do plants (trees) through the process of photosynthesis in the leaves. Over energy aid from the sun, the water is absorbed from the soil plants will be mixed with the CO2 is absorbed from the air to produce sugars, organic material that is needed to grow and develop. 

More and more plants (trees) will be more and more also leaves that absorb CO2, so the concentration of CO2 in the air can be reduced. Thus the process of planting trees could reduce global warming. 

Actual photosynthetic process is one natural mechanism for maintaining the equilibrium concentration of CO2 in the atmosphere, in addition to dissolution of CO2 in the ocean due to wind and rain, and because the process of cooling the air. This is where the forest becomes important. 

Reduced forest area due to clearing and conversion to other purposes such as residential and industrial areas, a factor that accelerates the increased concentration of CO2 in the atmosphere in recent decades. 

Therefore, tree planting and reforestation of critical areas is an important step to reduce global warming. 

Incessant publicity about the phenomenon of global warming and its impact has raised awareness in the various circles of society in the world to participate against the rise in temperature of the earth. 

The Indonesian government held a one billion tree planting programs to achieve the target of reducing CO2 emissions by 26 percent in 2020. 

In Mississippi, United States, communities are competing to plant bamboo, in addition to reducing global warming is also to produce building materials and handicrafts. Even these groups perform a variety of research that produces bamboo species with a shorter harvest age. 

At the corporate level, environment-friendly production activities become as much competitive advantage by producing products labeled as environmentally friendly (eco-labeling). 

Surely not just planting trees make the air became cooler, but more than that, are not we realize that action contribute to the fight against global warming sehigga earth with all creatures in it spared from extinction.
