Green House effect.

<< < (4/6) > >>

Faizul Haque:
Greenhouse effect become  a great problem all over the world. So we should be aware about this.

Md. Mazedul Islam Mazed:
Greenhouse effect become  a great problem for the world. So we should be careful about it..

sethy:
What can you do to reduce the harmful effects of greenhouse gases
 We should
    *control the emission of pollutants from various automobiles.
    *try to use public transport instead of private vehicle.
    *factories and industries should control their pollution.
    *wastes should not be burned.
    * not to use aerosols.
    * not to burn fossil fuels
    *stop farting, smoking, driving

sethy:
We could try geoengineering techniques, however these methods are speculative, untested, and potentially dangerous in their own right, and the reduction of carbon emissions may still be additionally necessary.

Geoengineering methods include reducing global warming by reflecting the incident solar radiation, by emitting aerosols, increasing the reflectivity of the ground or clouds, or by using mirrors in space. The other geoengineering approach is to capture carbon from the atmosphere in artificial 'chemical trees' so it can be buried, or to encourage algae growth in the ocean which then fall to the deep ocean floor.

Our other alternative is to adapt human civilization and the biosphere to cope with the effects of climate change, through improved flood controls, a more flexible and expanded food supply, and the relocation or care of endangered species if possible.

We should however not become dependent on these methods, and try to reduce carbon emissions to the atmosphere by

    reducing carbon emissions by consuming less, or replacing consumables with alternatives which emit less carbon in their use and production.
    reducing the birth rate so the potential for future carbon emissions are reduced
    capture then contain or sequester (bury) carbon emissions to prevent them reaching the atmosphere. This includes artificial, and natural sinks such as forests.

sethy:
We can do lots of things, such as drive hybrid vehicles, use solar panels, and use alternative fuels.

The greenhouse effect cause, because of increase in heat trapping gases including Carbon dioxide CFCs & nitrogen. We can reduce greenhouse effect by stop or decrease in use of those instruments which emit these gases.
 

We can do many things to help, like;

Use less electricity, Ride your bike, and more.

But we don't want to eliminate the Greenhouse effect all in all, we have to have it. If we didn't have, or never did; the Earth's surface would be about 30 degrees Celsius colder. That would not work for our ecosystem that we are attained to now.


can help slow global warming by:

    Walking, riding your bicycle, or taking the bus instead of always going by car.
    Not wasting electricity (turn off the lights, the radio, the TV and the computer when you're not using them).
    Reducing, reusing or recycling all kinds of items, from soda pop cans to clothes, to save energy and raw materials.
    Planting trees to help absorb excess CO2, and to provide shade and windbreaks to keep buildings at more even temperatures so they will require less energy for heating or cooling.
