What protects our eyes?

Our eyes are very delicate organs that need protection. Tears kill invading germs and our eyelids, eyelashes, and eyebrows help to keep out other harmful particles.

Our eyes’ first line of defence is eyelashes and eyelids. Our eyelashes form two rows of stiff hairs around each eye. They help to catch and remove any large particles that come too close to our eyes.

Our eyelids are equipped with muscles so that they can open and close. The reflex action that makes us close our eyes helps to protect them from being injured by objects or dazzled by the bright light.

Any dust or dirt that does reach our eyes is removed when we blink. Our eyelids close briefly, sweeping across the front of our eyeballs.

The eyebrows form two long patches of protective hairs above our eyes. They prevent moisture on our forehead from running down into our eyes.

Where do we find the Continental Climate and what are its main features ?

The Continental Climate is found in the interior part of the big continents between Taiga and the mid-latitude deserts. In Eurasia, it spreads from Poland and the Baltic States to the Central Russian plain. Beyond the Ural mountains, the belt is narrow and runs along the 55 degrees parallel.

In North America, this climate is found in the northern states of the USA and the southern parts of the central states of Canada. In continental climate summers are short and warm, the temperature being in between 10° C and 21° C.

Winter is long and temperature goes down below freezing point. Precipitation is variable and comes mostly in summer as rainfall. Winter precipitation is in the form of snow.

How does solar cooker functions?

By its very name, a Solar Cooker would mean cooking meals with solar energy without any conventional fuel. The cooker is so simple that after buying the required material from the market, any carpenter can fabricate it. Materials include mirror, cooking pots, glass sheets (two) with half distance in parallel, glass sheet frame and a blackened

aluminium tray, a wooden box, handle, thumb nut and lunged adjustor and guide. Besides the above, insulating material (glass wool) is filled in the space between a wooden box and aluminium tray all round. There is also a castor wheel fitted on one side for easy handling.

The sun’s rays enter through glass sheets inside the box. The black surface area absorbs solar radiation which is transformed into thermal radiation, and cannot be easily re-radiated out of the glass sheets. The loss of heat through conduction and convection is minimised by insulating space and making the box air tight. This is why the temperature inside the Solar Cooker can be as high % as 125° to 160° centigrade.

In Solar Cooker, food is cooked by the heat absorbed from solar rays; food is, therefore, cooked during daytime only when the whole place is drenched in sunlight.

Rio+20 Conference
The UN Conference on Sustainable Development, also known as Rio 2012 or Rio+20, was held during June 20-22, 2012 in Rio de Janeiro, Brazil. The conference was organised by the United Nations Department of Economic and Social Affairs. Rio+20 was a 20-year follow-up to the historic 1992 United Nations Conference on Environment and Development (UNCED) held in the same city. Rio+20 was a key milestone in a series of major UN conferences; the 1992 UNCED was the centrepiece of the series as it put sustainable development on top of the priority list in the agenda of the UN.

The 192 countries that participated in the summit agreed that poverty eradication should be given the highest priority, overriding all other concerns to achieve sustainable development. There were bitter arguments between the developed and the developing nations on this issue. The developing ones put a premium on eradicating poverty, while the developed ones wanted poverty eradication to be made subservient to creating a “green economy”. The proposal of giving priority to poverty eradication, first put forward by India, found unwavering backing from the G77 countries. The final draft of the Rio+20 stated, “Eradicating poverty is the greatest global challenge facing the world today and an indispensable requirement for sustainable development”.
The European nations had specifically pitched the Rio+20 summit as a “green” summit. They advocated that the participating heads of states should endorse a common green solution for the entire world. They also said that the leaders should force a time-bound road map for the countries to shift to costlier clean modes of production. The G77 developing countries bloc demanded a $30-billion fund for sustainable development starting 2013. The developed nations had stalled negotiations on how the world should fund the move towards sustainable development.
By way of this, the developed nations intended to reduce their existing obligations to provide money and technology to poor nations. However, the demand for funds compelled the EU and the US to take a middle ground and agree to setting up an inter-governmental process for determining where funds and technologies would come from to achieve the sustainable development goals. It was announced that the exact procedure would be elaborated through a negotiating process over the next few years.
