Plants are living organisms belonging to the kingdom Plantae. They include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The scientific study of plants, known as botany, has identified about 350,000 extant species of plants, defined as seed plants, bryophytes, ferns and fern allies. As of 2004, some 287,655 species had been identified, of which 258,650 are flowering and 18,000 bryophytes (see table below). Green plants, sometimes called Viridiplantae, obtain most of their energy from sunlight via a process called photosynthesis.

The good news for us all: there are solutions to minimize global warming, and now we still have a chance to do so. All we need is a strong willingness to change!
Basically, we have to do is to reduce as much as possible all the activities that produce greenhouse gas emissions. There are five main things we can do to save the planet earth:
1. Stop or reduce eating meat!
In his report entitled Livestock’s Long Shadow: Environmental Issues and Options (released November 2006), the UN noted that 18% of global warming is happening right now was donated by the farming industry, which is greater than the effects of global warming generated by the entire world transportation combined! The UN also added that the emissions are calculated only on the basis of the resulting CO2 emissions, but other than CO2 as a great contributor, farming industry is also one of the major sources of pollution of soil and water sources clean.
A report from Earth Institute affirms that plant-based diet requires only 25% of the energy needed by the meat-based diet. Research carried out Professor Gidon Eshel and Pamela Martin from the University of Chicago also gave the same conclusion: changing patterns of eating a vegetarian diet with 50% more effective in preventing global warming instead of replacing an SUV with a hybrid car. A vegetarian with a standard American diet will save 1.5 tonnes of greenhouse emissions every year! A vegetarian driving a Hummer SUV is more environmentally friendly than a meat eater riding a bicycle!
2. Limit emissions of carbon dioxide!
If possible, look for sources of alternative energy sources that do not produce CO2 emissions such as solar energy, water, wind, nuclear, and others. When forced to use fossil fuels (which will result in CO2 emissions), use it wisely and efficiently. Matikanlah peralatan listrik ketika tidak digunakan, gunakanlah lampu hemat energi, dan gunakanlah panel surya sebagai energi alternatif. This includes electricity and energy saving, especially Indonesia, including many countries that use fossil fuels (oil, coal) for generating electricity. Turn off electrical appliances when not in use, use energy efficient lighting, and use solar panels as alternative energy.
3. Plant more trees!
Green plants absorb CO2 from the atmosphere and store it in the network. But after death they will release CO2 into the air again. Environment with lots of CO2 plants will bind well, and should be maintained by future generations. If not, then the carbon already stored in the plant will re-released into the air as CO2.
Researchers from Louisiana Tech University found that each acre of green trees can capture enough carbon to offset emissions resulting from driving a car for a year. A study conducted by the forestry service in the United States also showed that planting 95,000 trees in two dlakukan small town in Chicago provides cleaner air and save costs associated with heating and cooling air for more than U.S. $ 38 million in 30 years to front.

Control of global warming
Total consumption of fossil fuels in the world increased by 1 percent per year.The steps being taken or are being discussed right now no one can
prevent global warming in the future. The challenge today is to overcome the effects while taking steps to prevent further climate changes in the future.
Damage can be overcome in various ways. Coastal areas can be protected by walls and barriers to prevent entry of sea water. Alternatively, governments can help the population in coastal areas to move to higher ground. Some countries, such as the United States, could save plants and animals while maintaining the corridor (line) habitat, clearing land that has not been built from south to north. The species can gradually move along this corridor to go to a cooler habitat.
There are two main approaches to slow the increasing greenhouse gases. First, to keep carbon dioxide into the atmosphere by storing the gas or its carbon component somewhere else. This is called carbon sequestration (removing carbon). Second, to reduce production of greenhouse gases.
Removing carbon
The easiest way to remove carbon dioxide in the air is to maintain trees and plant trees more. Trees, especially young and fast growing, absorb carbon dioxide very much, breaking through photosynthesis and store carbon in the wood. Around the world, clearing the forest has reached alarming levels. In many areas, plants that grow back a bit because the soil loses its fertility when modified for other uses, such as for agriculture or housing development. Steps to overcome this is to reforestation that play a role in reducing the increase in greenhouse gases. Read more…
Impact of global warming
Scientists use computer models of temperature, precipitation patterns, and atmosphere circulation to study global warming. Based on these models, scientists have made some predictions about how global warming will affect weather, sea levels, coastal, agricultural, wildlife and the health of humans.
Climate Start Unstable
Scientists predict that during global warming, the northern part of the Northern hemisphere (Northern Hemisphere) will heat up more than other regions on Earth. As a result, icebergs will melt and the land will shrink. Will be less ice will float on northern oceans. Areas that previously experienced light snow, may not be there again. In the mountains in subtropical areas, snow-covered parts will be less and will melt faster. Growing seasons will be longer in some areas. Temperatures in the winter and at night would tend to increase.
Warmer regions will become more humid as more water evaporates from the ocean. Scientists are not sure whether the moisture is actually going to increase or decrease heating further. This is because water vapor is a greenhouse gas, so that its presence will increase the effect of insulation in the atmosphere. However, the more water vapor will also develop a lot more clouds, which would reflect sunlight back into space, where it will reduce the heating process (see the water cycle). High humidity will increase rainfall, on average, about 1 percent for each Fahrenheit degree of warming. The storm will become more frequent. In addition, the water will evaporate faster than the ground. Some regions will become drier than ever. Winds will blow harder and perhaps with a different pattern. Hurricane (hurricane) that obtain power from the evaporation of water, will become larger. Contrary to the warming is happening, some very cold periods will probably happen. Weather patterns become more unpredictable and extreme.
Increasing sea level
Changes of average height measured from sea-level areas with a stable environment in geology.
As the atmosphere warms, the ocean surface layer will be warmer, so the volume will grow and raise the sea level. Warming will also melt much glacier ice, especially around Greenland, further swelling the sea. Sea levels worldwide rose 10 – 25 cm (4 – 10 inches) over the 20th century, and IPCC scientists predict a further rise of 9 to 88 cm (4 to 35 inches) in the 21st century.
Sea-level changes will complicate life in the coastal region. Increase of 100 cm (40 inches) would sink 6 percent of the Netherlands, 17.5 percent of Bangladesh, and many islands. Erosion of cliffs, beaches, and dunes will increase. When the high seas to reach the mouth of the river, flooding caused by high water will rise on the mainland. Rich countries will spend huge amounts of money to protect the shorelines, while poor countries may simply evacuate from coastal areas. Read more…
Global Warming is the process of increasing temperatures average atmosphere, sea, and land Earth.
The average temperature at Earth’s surface globally has increased 0.74 ± 0:18 ° C (1:33 ± 0:32 ° F) during the last hundred years. Intergovernmental Panel on Climate Change (IPCC) concluded that, “most of the increase in average temperatures since the mid-century global the 20 most likely caused by increased concentrations of gas-greenhouse gases due to human activities ” via the greenhouse effect.These basic conclusions have been expressed by at least 30 scientific and academic bodies, including all the national science academies of the countries the G8. However, there are still some scientists who disagree with some of the IPCC conclusions are presented.
Climate models referenced by the IPCC project shows the global surface temperature will rise 1.1 C to 6.4 ° (2.0 to 11.5 ° F) between 1990 and 2100. The difference estimate was caused by using different scenarios of greenhouse gas emissions – greenhouse gases in the future, as well as models of different climate sensitivities. Although most research focuses on the period up to 2100, warming and sea level rise is expected to continue for more than a thousand years, although the level of greenhouse gas emissions have stabilized. This reflects the large heat capacity of the ocean.
Increasing global temperature is expected to cause changes such as sea level rise, increased intensity of extreme weather phenomena, and changes in the number and pattern of precipitation. The consequences of global warming is terpengaruhnya crops, loss of glaciers, and the extinction of various species of animals.
Some of the things that scientists still doubt is about the amount of warming predicted to occur in the future, and how warming and the changes that occur will vary from one region to another. Until now still going political and public debate in the world about what, if any, action should be taken to reduce or reverse further warming or to adapt to the consequences that exist. Most of the government of the countries in the world have signed and ratified the Kyoto Protocol, which leads to the reduction of gas emissions, greenhouse gases.
