For Our Mother Earth

For over the past 200 years, the burning of fossil fuels, such as coal and oil, and deforestation have caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. These gases prevent heat from escaping to space, somewhat like the glass panels of a greenhouse. Greenhouse gases are necessary to life as we know it, because they keep the planet's surface warmer than it otherwise would be. But, as the concentrations of these gases continue to increase in the atmosphere, the Earth's temperature is climbing above past levels. Scientists are certain that human activities are changing the composition of the atmosphere, and that increasing the concentration of greenhouse gases will change the planet's climate.
As you can see, climate around the world has change. If we do not do anything now, by 2100, half of the world living species might be extinct and millions of people will suffer from drought and famine.
In order to prevent such catastrophe from happening, we have to start doing something from now. Time is running out and there is a few ways we can help our mother Earth.

Shopping: by making strategic consumer choices, one can reduce the production of greenhouse gases. Purchasing energy-efficient products helps reduce the release of greenhouse gases into the atmosphere. For example, aluminium packaging has a much more energy intensive production process than plastic packaging, and therefore higher greenhouse emission.
Recycling: Buying products that are reusable or recyclable, or contain reduced packaging, can save a significant part of the energy and resources required for manufacturing new goods. By recycling paper, cardboard, glass or metal, an average family could reduce their carbon dioxide emissions by up to one ton annually. Cutting down on products used around the home, especially power-intensive electric products such as desktops, can have a large effect on overall emissions.
Public transport: More frequent use of public transportation helps the environment by reducing the time spent in cars. Boats and ferries are the most efficient method of fossil fuel transport, followed by trains, then buses. Aeroplanes can be more than ten times less energy-efficient than cars. Walking is the least impactful mode of transportation, followed by the bicycle, whose usage produces no carbon emissions. (However, the manufacturing of bicycles can emit carbon dioxide and other pollutants.)
Trees: Protecting forests and planting new trees contributes to the absorption of carbon dioxide from the air. There are many opportunities to plant trees in the yard, along roads, in parks, and in public gardens. In addition, some charities plant fast-growing trees -- for as little as $US0.10 per tree -- to help people in tropical developing countries restore the productivity of their lands. Conversely, clearing old-growth forests adds to the carbon in the atmosphere, so buying non-old-growth paper is good for the climate as well as the forest.
Labels: The Energy Star label can be seen on many household appliances, home electronics, office equipment, heating and cooling equipment, windows, residential light fixtures, and other products. Energy Star products use less energy.
Cars: Buying a car can be a weighty decision. Purchasing an energy-efficient vehicle helps to reduce emissions of carbon dioxide.
Electricity: Minimise the use of electricity will help to reduce emission of carbon dioxide by power plants that run on fossil fuels.
Renewable energy: The use of alternative energy sources, such as solar, wind, geothermal, and hydro energy, is gaining increased support worldwide. The wind energy produced in Denmark, for example, provides about 10 percent of the country's total energy needs. These methods of energy production emit no greenhouse gases once they are up and running. Many energy suppliers in various countries worldwide have options to purchase part or pure "green energy."
Using less animal products: The United Nations' Food and Agriculture Organization reports that rearing livestock contributes more greenhouse gases than all fossil fuel burning combined. A 2006 study from the Department of Geophysical Sciences at the University of Chicago found the difference between a vegan diet and red meat diet is equivalent to driving a sedan compared to a sport utility vehicle

I hope the tips above will give everyone a guide into helping our Earth. For a better future, start preserving our planet Earth now!
