Trees for a greener earth
Every year on March 21st in the southern hemisphere and the vernal in the northern hemisphere is observed the world forestry day to improve public awareness about the importance of forests.. So we should save our forests to protect livelihood. While talking about economic growth we are moving from ‘need to greed’ and we do not take our fundamental resources air, water, soil and trees into consideration. It is time our younger generation to take initiatives to save trees with an approach to spread environmental awareness among the children o the country. To encourage the youth eco programs should be conducted. Creative eco activities to celebrate trees like tree planting, conducting tree quiz, skits based on conserving trees, taking out rallies, poster competitions.
Cutting down trees on a massive scale has greatly affected the environment around us and it has become imperative to do something about their conservation. The festival of trees (Van Mahotsav in India) is not just about forest and tree planting it is about our immediate surroundings. Trees are planted on railway lines, periphery of lakes, wastelands, in homes and balconies. It is heartening to see that almost everyone from old to young children are interested to plant a sapling. In schools and colleges saplings should be distributed to create enthusiasm of planting trees. Planting of trees is a symbolic gesture to celebrate our reverence for all things that grow in the forest. A step towards protecting the green cover and our environment.
Humankind has inadvertently declared war on the planet that gave us life. It is our duty to lend a healing hand to our beautiful planet. Planting trees is seen as one of the most important things the average man in the street can do, not because of its environmental impact, but instead because of its motivational power within communities. Can we just imagine, if all people planted one tree, our world would be greener and that would mean more trees would help in the raging battle against global warming.
Why should we plant a tree?
1)Trees provide oxygen
2)Trees clean the air: Trees help cleanse the air by intercepting airborne particles, reducing heat, and absorbing pollutants such as carbon monoxide, sulphur dioxide, and nitrogen dioxide, absorb the carcinogens.
3)Trees Shade and Cool : Trees provides shade to weary travelers, reduces the need for fan, coolers and air conditioning in summer.
4)Trees Become dustbins for harmful gases : a tree absorbs and locks away carbon dioxide, and other harmful gases which warm the environment. An urban forest is a carbon storage area that can lock up as much carbon.
5)Trees Act as Windbreaks: trees break the force of the wind. This protects houses, farmland and vegetation.
6)Trees Fight Soil Erosion: Trees fight soil erosion, conserve rainwater, and reduce water runoff and sediment deposit after storms
7)Trees help in lowering the dust levels and pollution levels in the cities.
8)Trees decrease respiratory problems; Children staying in areas and localites with trees have much less breathing problems that children staying in localities which have no trees.
9)Provide fuel and thus release cow dung for use as manure. Trees provide habitat for species of many kinds -- including endangered species.
10)Trees provide clean water and natural flood control. Forests act as natural reservoirs, and they protect watersheds, providing clean water for cities, bays and rivers.
Trees are a beautiful part of our lives. From striking individual trees that are of historic significance or are simply large and majestic, to a grove of trees in a city park, trees enrich our lives by simply being there. Trees are not just a key to the natural ecosystem -- trees are an essential part of community life.

-It is named for the olive (green) color of its heart-shaped shell.
-It is the smallest sea turtle, usually less than 100 pounds (45 kilograms).
-Male olive ridleys can be distinguished from females by their tails, which stick out beyond their carapace.
-Rough estimates put the worldwide population of nesting females at about 800,000, but its numbers, particularly in the western Atlantic have declined precipitously. The United States lists the western Atlantic population of olive ridleys as endangered and all other populations as threatened.
-The Olive Ridley is found in the tropical waters of the northern Indian Ocean, the eastern Pacific Ocean, and in the eastern Atlantic along the coast of Africa. Orissa is known the world over as the biggest nesting site for Olive Ridley turtles. It has three mass nesting sites
- Nasi Islands in Kendrapada district,
-mouth of Devi river in Puri district and
-mouth of Rushikulya river in Ganjam district.
-In addition, the turtle is an important symbol in the mythologies of many indigenous cultures, usually representing creation, longevity, and wisdom in these belief systems. Turtles are thus truly ancient beings-both in geological and mythological terms. Hindu mythology worships sea turtles as an incarnation of one of their gods. Thus, most fishing communities along the coast do not consume turtle eggs or meat.
-The olive ridley is small and lightly built for a sea turtle. It feeds on small shrimp, jellyfish, crabs, snails and fish, which it crushes with strong jaws. The olive ridley dines primarily on marine invertebrates including crabs, clams, shrimps and mussels. They crush and grind their food with their strong jaws. Sea urchins, squid and jellyfish are also part of the menu. When feeding, these turtles can dive up to 550 feet.- Marine turtles fulfill important roles in marine ecosystems. Olive Ridley turtles feed on invertebrates and may play important roles in both open ocean and coastal ecosystems.
-Genetic studies say that the species found in the Orissa coast is the most ancient of species.
-Olive ridleys have small heads and small, olive gray shells that measure around two feet in length. Their carapace color varies with geographic location. Western Atlantic animals are usually lighter than ones in the Eastern Pacific. They weigh between 70 to 100 pounds.
-Conservationists from across the world have been petitioning the Indian and state governments to protect the turtles.
-Estimations are that over 150,000 of these turtles have been killed in the last ten years.
-Olive Ridley turtles are endangered and protected under the Wildlife Protection Act of 1972. Trapping or killing an Olive Ridley turtle can lead to imprisonment for seven years.
-The decline of this species is primarily due to capture in commercial fisheries, loss of nesting habitat and the direct harvest of adults and eggs.
- According to the 1998 Orissa High Court Order, 'only' up to 50 trawlers and 300 country boats should be allowed per day into the sea in this region during Olive Ridley's nesting period. But in reality, there are about 250 trawlers and 35 trawlers, in Paradeep and Astarang respectively. A seasonal fishing ban is in place within a 20 km radius of the three major breeding grounds - Gahirmatha, Devi river mouth and the Rushikulya river mouth but apparently this is violated with impunity. It has been made mandatory for all trawlers to have TED (Turtle Excluder Device) before they are issued license, yet TEDs are not in use, primarily because of the misplaced apprehension that use of TED would lead to drastic reduction in fish catch, besides poor enforcement and monitoring.Olive Ridley turtles are endangered and protected under the Wildlife Protection Act of 1972. Though the laws have been made for a nobel cause, due to the uneffective implementation of the laws by the law-makers, the number of law-breakers and hence the no. of turtle deaths are very high

It is a very common and heart touching site to see carcasses of Olive Ridleys lying in the Paradeep beach, which is close to the breeding site of the Olive Ridleys. Hence we decided to address to the issue. We requested Amartya's mother who is the President of a local ladies club to call Mr Sudarshan Pattnaik for an Olive Ridley awareness campaign.Here we told the assembled gathering about the importance and protection of the Olive Ridley Turtles.

These are two paper cuttings taken from the "The Times Of India"
1) The first one highlights the uneffective implementation of laws related to protection of Olive Ridleys.
2) The second one shows the role of students in conservation of the creatures.
