Good Morning Readers!!! I was just thinking, did people really know what's global warming? and what cause it? Maybe if they know some information, they will at least protect this world from global warming issues?
So lets talk about global warming, today hot issues that you must know guys!! enjoy read while drink your morning coffee.. Here we go :)

Our world is changing.
In fact earth has always been changing and will continue to do so for ages to come. But there is difference between the changes before and today's. And the cause of this is HUMAN ACTIVITY.
Humans have generated local polution ever since they first developed agricultural societies around 10,000 years ago.

Global Warming is the Effect of Greenhouse Effect.
What is Greenhouse effect?

The greenhouse effect is a natural physical process that operates in all planetary atmospheres. But somehow the normal temperature from greenhouse effect on earth is 15 degree of Celcius, now is getting higher and higher because Earth Greenhouse gases.
Here is the different between Normal Greenhouse Effect and the Enhanced Greenhouse Effect:

Greenhouse Gasses.
Greenhouse gases trap heat in the atmosphere, which makes the Earth warmer. The most abundant anthropogenic greenhouse gas on Earth is Carbon dioxide, which is produced by fossil fuels(such as coal, oil, natural gas) and deforestation. Greenhouse gases come from all sorts of everyday activities, such as using electricity, heating our homes, and driving around town.

The Greenhouse Effect - Possible Solutions:
1. Reducing use of fossil fuels would considerably reduce the amount of carbon dioxide produced, as well as reducing the levels of the pollutants which cause acid rain. This can be achieved by either using less energy altogether, or using alternative energy sources. You can help save energy in lots of ways:
        Turn off lights when you leave a room.
        If you have a car, don't use it for short journeys.
        Basically, anything at all that uses less energy. 
2. Eliminating the use of CFCs is something we can actually do. Chlorofluorocarbons (CFCs) were invented in the 1920s; they are a compound of carbon containing chlorine and fluorine. CFCs are man made chemicals, so we call them synthetic chemicals. Since their introduction CFCs have been used as:
        Refrigerants in refrigerators and air conditioning units.
        Propellants in aerosol cans.
        Foaming agents in the production of packaging.
        Cleaners used in the electronics industry.
        Fire extinguisher chemicals.
3. New refrigerants have been developed, and new aerosols use other propellants such as butane, so it is now actually quite difficult to get hold of CFCs (assuming you wanted to get some for something anyway).
4. Stopping deforestation by using renewable forests and planting a new tree whenever one is felled would help to raise the carbon dioxide absorbing ability of the planet.
