Paper Bags or Plastic Bags?

Paper Bags or Plastic Bags?

by Collin Dunn, Corvallis, OR, USA on 07. 9.08

Paper or plastic bags: which is better?
It's an age old question, when it comes time to check out when grocery shopping: paper bag or plastic bag? It seems like it should be an easy choice, but there's an incredible number of details and inputs hidden in each bag. From durability and reusability to life cycle costs, there's a lot more to each bag than meet the eye. Let's take a look behind the bags.

Where do brown paper bags come from?
Paper comes from trees -- lots and lots of trees. The logging industry, influenced by companies like Weyerhaeuser and Kimberly-Clark, is huge, and the process to get that paper bag to the grocery store is long, sordid and exacts a heavy toll on the planet. First, the trees are found, marked and felled in a process that all too often involves clear-cutting, resulting in massive habitat destruction and long-term ecological damage.

Mega-machinery comes in to remove the logs from what used to be forest, either by logging trucks or even helicopters in more remote areas. This machinery requires fossil fuel to operate and roads to drive on, and, when done unsustainably, logging even a small area has a large impact on the entire ecological chain in surrounding areas.

Once the trees are collected, they must dry at least three years before they can be used. More machinery is used to strip the bark, which is then chipped into one-inch squares and cooked under tremendous heat and pressure. This wood stew is then "digested," with a chemical mixture of limestone and acid, and after several hours of cooking, what was once wood becomes pulp. It takes approximately three tons of wood chips to make one ton of pulp.

The pulp is then washed and bleached; both stages require thousands of gallons of clean water. Coloring is added to more water, and is then combined in a ratio of 1 part pulp to 400 parts water, to make paper. The pulp/water mixture is dumped into a web of bronze wires, and the water showers through, leaving the pulp, which, in turn, is rolled into paper.

Whew! And that's just to make the paper; don't forget about the energy inputs -- chemical, electrical, and fossil fuel-based -- used to transport the raw material, turn the paper into a bag and then transport the finished paper bag all over the world.

UNEP: Global Green New Deal

UNEP: Global Green New Deal


unep_logoA major study by the United Nations Environment Programme (UNEP) concludes organic farming offers Africa the best chance of breaking the long inherent cycle of poverty and malnutrition.

Mobilizing and re-focusing the global economy towards investments in clean technologies and 'natural' infrastructure such as forests and soils is the best bet for real growth, combating climate change and triggering an employment boom in the 21st century. The new survey by the UN Conference on Trade and the Environment and UNEP in East Africa found that over 90 per cent of studies show that organic or near organic agriculture had benefits for soil fertility, water control, improved water tables, carbon sequestration and biodiversity.

Greenhouse gases may steal oxygen from the oceans

Greenhouse gases may steal oxygen from the oceans


oceansContinous emissions of greenhouse gases may slowly but dramatically impoverish the oceans of oxygen, with negative effects that could continue for thousands of years in life of fishes and other sea animals.
This is the scenery resulting from the simulations drawn in the web edition of the scientific journal Nature Geoscience and elaborated by Gary Shaffer's Danish team of Copenaghen University. In the scholars' opinion the oceans' impoverishment may be an effect of global warming. This could become a real fact in the next 100,000 years if a drastic reduction of fossil fuels is not implemented soon.
Shaffer's team took into account two situations related to emmissions of fossil fuels, and both simulations revealed a loss of oxygen in the oceans’ surface. As a consequence, the process that now rapidly brings in depth the superficial and oxygenised waters will be much slower.

Why Plastic Bag should be ban by us personally ?

Why We should ban personally plastic bags ? It's simple !

Just Simple to assign its feature and our reason to ban it in our daily life.

Plastic bags are not biodegradable. They clog waterways, spoil the landscape, and end up in landfills where they may take 1,000 years or more to break down into ever smaller particles that continue to pollute the soil and water.

Plastic bags also pose a serious danger to birds and marine mammals that often mistake them for food. Thousands die each year after swallowing or choking on discarded plastic bags.

Finally, producing plastic bags requires millions of gallons of petroleum that could be used for transportation or heating.

Renewablae Energy : We need it badly

Renewable energy resources are kind of those energy which are not destructing itself for producing energy for us, such as wind, solar and hydropower. This kind of energy offer clean alternatives to fossil fuels. They produce little or no pollution or greenhouse gases, and they will never run out.


Solar Energy

The best energy resources we have in this planet is The sun. Sunlight, or solar energy, can be used for heating, lighting and cooling homes and other buildings, generating electricity, water heating, and a variety of industrial processes.

Moreover, Most forms of renewable energy come either directly or indirectly from the sun. For example, heat from the sun causes the wind to blow, contributes to the growth of trees and other plants that are used for biomass energy, and plays an essential role in the cycle of evaporation and precipitation that makes hydropower possible.

So We can call The Solar Energy Resource as "Premio resource of Recyclable Energy".


Wind Energy

After Solar power, we can assume Wind is secondary resources as recyclable energy generating factor. Wind is the movement of air that occurs when warm air rises and cooler air rushes in to replace it. The energy of the wind has been used for centuries to sail ships and drive windmills that grind grain.

At present, researchers are expressing their own view for wind energy which is captured by wind turbines and used to generate electricity.


Hydropower

This is also secondary resources of recyclable energy. Where Water flowing downstream powerfully there it is a powerful force.

As we know, Water is a renewable resource, constantly recharged by the global cycle of evaporation and precipitation. The heat of the sun causes water in lakes and oceans to evaporate and form clouds. The water then falls back to Earth as rain or snow, and drains into rivers and streams that flow back to the ocean. Flowing water can be used to power water wheels that drive mechanical processes. And captured by turbines and generators, like those housed at many dams around the world, the energy of flowing water can be used to generate electricity.


Biomass Energy

Now a days, Biomass has been an important source of energy.

With wood , people are promoting the most common source of biomass energy, but other sources of biomass energy include food crops, grasses and other plants, agricultural and forestry waste and residue, organic components from municipal and industrial wastes, even methane gas harvested from community landfills.

Biomass can be used to produce electricity and as fuel for transportation, or to manufacture products that would otherwise require the use of non-renewable fossil fuels.


Hydrogen

Primarily, we can say this is next-generation technology as recyclable energy resource. Hydrogen has tremendous potential as a fuel and energy source, but the technology needed to realize that potential is still in the early stages.

Hydrogen is the most common element on Earth—for example, water is two-thirds hydrogen—but in nature it is always found in combination with other elements. Once separated from other elements, hydrogen can be used to power vehicles, replace natural gas for heating and cooking, and to generate electricity.


Geothermal Energy

The heat inside the Earth produces steam and hot water that can be used to power generators and produce electricity, or for other applications such as home heating and power generation for industry.

Geothermal energy can be drawn from deep underground reservoirs by drilling, or from other geothermal reservoirs closer to the surface.


Ocean Energy

The ocean, the big ocean. As we know we are surroundings by these oceans and it has provides several forms of renewable energy, and each one is driven by different forces.

Energy from ocean waves and tides can be harnessed to generate electricity, and ocean thermal energy—from the heat stored in sea water—can also be converted to electricity. Using current technologies, most ocean energy is not cost-effective compared to other renewable energy sources, but the ocean remains and important potential energy source for the future.

All above, with some home and with some desire to make our planet alive.

To prevent Global Warming We need to maintain few steps

We know, Greenhouse effects just hampering our planets subsistence level. Global Warming Predictions are jumping like following picture :


To prevent Global Warming more, Researchers always trying to find some general methods to restrict this as;

1. Reduce, Reuse, Recycle products instead of disposables.

2. Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste.

3. Whenever you can, recycle paper, plastic, newspaper, glass and aluminum cans.
[
By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually.]

4. Use Less Heat and Air Conditioning can lower your heating costs more than 25 percent, by reducing the amount of energy we can reduce increase of carbon-di-oxide in our air.

5. Turn down the heat while you’re sleeping at night or away during the day, and keep temperatures moderate at all times. Setting your thermostat just 2 degrees lower in winter and higher in summer could save about 2,000 pounds of carbon dioxide each year.

6. Replace regular light bulbs with compact fluorescent light (CFL) bulbs. Replacing just one 60-watt incandescent light bulb with a CFL will save you $30 over the life of the bulb. CFLs also last 10 times longer than incandescent bulbs, use two-thirds less energy, and give off 70 percent less heat.

7. Less driving means fewer emissions. Besides saving fuel, walking and biking are great forms of exercise. Explore your community’s mass transit system, and check out options for carpooling to work or school. Less Driving means more walking also, which is a part of fitness and regular exercise. It can make your health fit too.


8. Home appliances are now in a range of energy-efficient models, and compact florescent bulbs are designed to provide more natural-looking light while using far less energy than standard light bulbs.

9. Avoid products that come with excess packaging, especially molded plastic and other packaging that can't be recycled. If you reduce your household garbage by 10 percent, you can save 1,200 pounds of carbon dioxide annually.

10. Use Less Water, save water for more usages.

It's also a good idea to turn off the water when you're not using it. While brushing your teeth, shampooing the dog or washing your car, turn off the water until you actually need it for rinsing. You'll reduce your water bill and help to conserve a vital resource.

11. Save electricity and reduce global warming by turning off lights when you leave a room, and using only as much light as you need. And remember to turn off your television, video player, stereo and computer when you're not using them.

12. Plant a tree, start digging. During photosynthesis, trees and other plants absorb carbon dioxide and give off oxygen. A single tree will absorb approximately one ton of carbon dioxide during its lifetime.

13. Share information about recycling and energy conservation with your friends, neighbors and co-workers, and take opportunities to encourage public officials to establish programs and policies that are good for the environment.

These few steps will take you a long way toward reducing your energy use and your monthly budget. And less energy use means less dependence on the fossil fuels that create greenhouse gases and contribute to global warming.
