The global climate has always fluctuated. Millions of years ago, some parts of the world that are now quite warn, were covered with ice, and over recent centuries, average temperature have risen and fallen in cycles. What is new, however, is that current and future climate change will be caused not just by natural events but also by activities of human beings. Suggest three simple ways to help save our planet.

Explanation

(1) Derive less. Walk, Carpool or take Public Transpot. You will save emission of `1.5 kg` of `CO_2` for every `5 km` you do not drive.
(2) Use renewable energy. Use 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 by sunlight. A solar cooker cooks food without losing its essential nutrients.
(3) Check your tyres. Keeping your tyres proprely inflated improves the fuel efficiency of your vehicle. Every litre of petrol saved, keeps `2.5 kg CO_2` out of atmosphere. Using radial tyres will help you save `3 %` to `7 %` of fuel.
