Manusia membongkar tumpukan CO2 yg tersimpan berkatfotosintesis (pembakaran Bahan Bakar Fosil -bensin, gas, -batubara)

Manusia melubangi lapisan ozone (O3), yg bahanpenyusunnya (O2) dihasilkan dari fotosintesis

sehingga mengakibatkan “rumah kaca”

sehingga bumi kurang terlindungi dari sengatan UV matahari

Bagaimana hal tersebut terjadi ?

Because greenhouse gas emissions are tied very closely to ourenergy consumption, using less fossil fuel based energy puts fewergreenhouse gases into the atmosphere.

This will help slow global warming.

Three 60 Watt Bulbs


We can make some simple substitutions

Replacing just 1 incandescent light bulb with 1 compactflorescent bulb saves about 150 pounds of carbondioxide per year!

If every American household replaced just 5 high-useincandescent bulbs with compact florescent lights we'dcollectively save more than $8 billion each year in energy costsand we would prevent the greenhouse gases equivalent to theemissions from nearly 10 million cars.
