Conservation of Grass

We grow crops or plants for many reasons. •Crops can be damaged which leads to reduced yields. •Therefore farmers need to protect crops against weeds, drought, veld fires and animals. 1.animals: •Plants need to be protected from animals like sheep, goats, donkeys and cattle. •These animals are grazers and browsers, so they destroy plants. •Therefore plants can be protected from the animals by using fences. •Barbed wire, or thorn bush wood can be used as fence. 2. Veld fires •Veld fire are usually experienced during the dry season. •These fires may destroy plants in fields and plantations. •Plants can be protected from veld fires by a fireguard. •A fireguard is a strip of land without grass on it. •A fire guard must be at least 9 metres wide. •The strip runs around the area planted to prevent the veld fires. 3. Drought •Drought is the shortage of rain water for a long time. •When plants do not enough water they wilt, resulting in poor growth and even death of plants. •Low rainfall also causes low yields and poor growth. •Drought can be protected by: ✓Plant drought resistant seeds. ✓Using irrigation ✓Practice water conservation methods such as mulching and terraces. 4. Weed control • Crops can be affected by weeds. •Weeds compete for nutrients with plants resulting in poor growth. • Some weeds provide shelter and food for pests that later attack the crop. •Weeds have to be removed from planting or transplanting until the end of the rainy season.

WHAT DOES THE WORLD GAIN WHEN WE PROTECT TIGERS? Tigers are one of the world’s most recognized animals. Throughout history they can be seen in cultural traditions across Asia, as well as in brand images and logos the world over. But while they might be omnipresent across our cultural landscape, their actual existence in the wild has been dramatically reduced to only a few pockets of their historical range. Wild tigers are now found in just 10 countries, their historical range shrunk by over 95%.er / WWF-US If tigers completely disappeared, we’d be losing so much more than an iconic species… Protecting water sources for millions of people Tiger habitats overlap nine of Asia’s most important watersheds which supply water to more than 800 million people. Protecting these tiger forests is the most cost-effective way to prevent droughts, reduce flooding, and limit the impacts of climate change. Protected Areas are proven to reduce deforestation and across Asia tigers are the driving force behind creating and effectively managing protected areas. For example, India recently declared its 51st Tiger Reserve, Srivilliputhur Megamalai, in southern India and this new protected area will safeguard more than 1,000km2 of key river habitat. Lose tigers, and lose entire forests Here in Cambodia, where I photographed the country’s last wild tiger in November 2007, tiger spirits were used by indigenous communities to help regulate the management of forests and wildlife. Harvesting of valuable plants was only permitted in certain times of the year and only after the tiger spirits had been appeased. Failure to adhere would result in wild tigers stalking you in the forest. However, with the extinction of the tiger the spirits have vanished, and the forests become an open free-for-all.aysia / Lau Ching Fong Protecting tigers also protects a multitude of other species Tiger-protected areas save much of Asia’s amazing wildlife. Take, for example, India’s Manas Tiger Reserve in Assam where tiger populations are increasing. In addition to tigers the grasslands and forests of Manas Tiger Reserve support the only viable global population of the world’s smallest, and rarest pig –pygmy hog – and, my personal favorite, the Bengal florican. This critically endangered gamebird, which I studied for my doctorate, finds a mate with an elaborate display involving males shooting themselves into the sky before plummeting down kicking their legs as if riding a bicycle. Without tigers, these and many more species would not be as well protected. A cultural and spiritual icon for millions There are plenty of examples of mythical animals, such as the unicorn, and extinct creatures, like the dodo and dinosaurs, which remain part of international consciousness. Tigers are a global phenomenon, but unless conservation is successful, they will only be known in zoos or in cultural media. A world without tigers would be economically and spiritually a much poorer place. Let us continue focusing our efforts towards doubling wild tigers and ensuring that this species does not become a vanished cultural icon.

Can you imagine what life would be if we run out of water? Very good! We can be very dirty as well as our environment! Do you know that water plays an important role n our lives? Yes, it is said that man can live for three days without food but not without water. OBJECTIVES: - States the importance of water in our lives - Practices ways to conserve water SCIENCE 2 – MODULE 8 SEIBO COLLEGE 16 Water is our life. It makes up the 50-90 percent of our body. Our cells will not be healthy if there’s no water. What do you feel when you are thirsty? Can you concentrate on the things that you are doing when you are thirsty? How about when you did not take a bath, how do you feel? Can you sleep at night comfortably without taking a bath? These are some things that remind us how important water is to us. So we need to learn to conserve it for us to enjoy it longer and for us to have enough supply of water for a long period of time. How can we participate in water conservation? Here’s how… Ways of Conserving Water 1. Turn off the faucet when not in use. Make sure it is tightly close. 2. When brushing teeth, use a glass to avoid wasting water. 3. When washing dishes, use enough water by using a basin. 4. When you observed that you water pipe is leaking, call a plumber immediately to fix it and avoid water from leaking. SCIENCE 2 – MODULE 8 SEIBO COLLEGE 17 5. Avoid frequent use of shower when taking a bath, use pail and dipper instead. 6. Never play with water. 7. Do not throw garbage or trash on the different sources of water. 8. Use watering can in watering plants to avoid excessive use of water. 9. Recycle used water. We can use water from the washing machine to clean our windows, comfort room and even our car. What are the things that you do at home that can help conserve water? Very good! You may now do the activities.

From both side of me i heard a gradual crescendo of excitement and laughter rippling along the trenches, interspersed with barked orders that everyone was to keep their heads down and no one was to shoot. From my vantage point on the mound I could see only an occasional glimpse of a steel helmet, my only evidence that the voices I was hearing did indeed belong to real people. There was the sweet smell of cooking food wafting towards me and I lifted my nose to savour it. It was sweeter than the sweetest bran-mash I had ever tasted and it had a tinge of salt about it. I was drawn first one way and then the other by this promise of warm food, but each time I neared the trenches on either side I met an impenetrable barrier of loosely coiled barbed wire. The soldiers cheered me on as I came closer, showing their heads fully now over the trenches and beckoning me towards them; and when I had to turn back at the wire and crossed no man’s land to the other side, I was welcomed again there by a chorus of whistling and clapping, but again I could find no way through the wire. I must have criss-crossed no man’s land for much of that morning, and found at long last in the middle of this blasted wilderness a small patch of coarse, dank grass growing on the lip of an old crater. I was busying myself at tearing the last of this away when I saw, out of the corner of my eye, a man in a grey uniform clamber up out of the trenches, waving a white flag above his head. I looked up as he began to clip his way methodically through the wire and then pull it aside. All this time there was much argument and noisy consternation from the other side; and soon a small, helmeted figure in a flapping khaki greatcoat climbed up into no man’s land. He too held up a white handkerchief in one hand and began also to work his way through the wire towards me.
