Question

A speech on 'Save Our Planet'

Answer 1

Use efficient lighting

Replace incandescent bulbs with compact fluorescents (CFLs). These use four times less energy and they last eight times longer. So you not only cut your electricity bills dramatically, you also save a lot of money on buying bulbs.

Use energy efficient electric appliances

They use two to 10 times less electricity for the same functionality and are mostly higher quality products that last longer than the less efficient ones. In short, efficient appliances save you lots of energy and money.

Use an energy efficient computer

Buy a laptop instead of a desktop. It consumes five times less electricity. If you buy a desktop, get an LCD screen. Enable the power management function on your computer, the screensaver does not save energy. Check if your computer supports the more advanced speedstep power management. Switching off a computer extends its lifetime, contrary to some misconceptions. Minimise printing and print on both sides of the paper. Laser printers use more electricity than inkjet printers.

Drive less

Walk, bike, carpool or take public transport. A 2011 study carried out by the European Cycling Federation compared carbon emissions from a bicycle (including manufacturing) to motorised vehicles and found that for every passenger kilometre travelled by bike, 21 grams of carbon were released as opposed to 271 grams for someone riding or driving in a car and 101 grams for people taking the bus.

Check your tyres

Keeping your tyres inflated properly can improve the fuel efficiency of your car. Every litre of petrol saved keeps 2.5 kg of carbon dioxide out of the atmosphere. Using radial tyres will help you save three to seven percent of fuel.

Use water carefully

Don't waste water. Use a mug of water when brushing your teeth, shaving or washing your hands and face. Instead of a shower or tub bath, use a bucket. Try to harvest rainwater in your locality. It takes a lot of energy to heat water- use less hot water and use efficient heating appliances.

Say no to plastic

Take a cloth bag with you when shopping. Use recycled paper. Avoid products with a lot of packaging.

Move your air-conditioning thermostat up two degrees

You could save about 900kg of carbon dioxide a year with this simple adjustment. Set the thermostat of the room air conditioner at 25C to get the most comfort at the least cost.

Use renewable energy

Sunlight can be used in many different ways to save energy. Use a solar water heater instead of an electric geyser. A 100 litre solar water heater can save around 1500 units of electricity every year. For lighting, use batteries that can be charged with sunlight. A solar cooker cooks rice and vegetables without losing their essential nutrients. Just leave the solar cooker outside in the sun to cook your food. If you live in a village, you can use biogas from cow-dung to save energy.

Plant more trees

A single tree will absorb one tonne of carbon dioxide over its lifetime.

Turn off electronic devices

Simply turning off your television, stereo, computer, fans, lights when you are not using them will save thousands of kilograms of carbon dioxide emissions a year.

Reuse & recycle

Recycling and re-using products like paper and bottles will help protect the environment. Use recycled paper. Recycle your office and household waste.

Answer 2

  'Save Our Planet'
-----------------------------------------------------------------------------------------------------
Earth is the most beautiful planet in the entire solar system and its the only plant which has life in it and no other planet has an suitable atmosphere like earth for our survival  and trees are most essential for the survival of all the species living on earth.

These days the human greed has no end and they are just destroying the forests everywhere for development purpose and slowly it will cause destruction of life on earth as tress are most essential for life. Moreover humans are causing a lot of pollution through industries , vehicles etc which will cause green house effect , global warming etc.

We need to save our mother earth at least for our future generation for that we need to stop cutting trees , stop pollution etc and ozone hole is the major problem now , we can stop the increasing of ozone hole and save our planet from the harmful UV radiations. To save earth we need to stop pollution , start planting more and more trees and use our resources ina propper manner and should follow sustainable development
