Plants grown in northern greenhouses: Tomatoes Tomatoes originate in South-America. The Maya people of Central America were very fond of tomatoes, they cooked and ate tomatoes. Today the tomato is an important ingredient in our everyday live and culture, whether we live in South America or not. Most people living nowadays have tomatoes, and while tomato is a big favourite among most people, the occasional few find it disagreeable. Tomato is the fruit of the Tomato plant (Solanum lycopersicum), a member of the family Solanaceae. Most varieties of tomatoes are spherical in shape, while pear-shaped varieties are also cultivated. Organic tomatoes are also widely available in supermarkets. Perhaps, the best way to serve tomato is as fresh vegetable on its own or as an ingredient of tomato salad or mixed salad. However, tomato is also a favourite ingredient of many dishes, ranging from casseroles, tomato sauce, pickles and chutneys. Fresh tomato juice is healthy addition to your diet. Tomato plants are grown in heated greenhouses in Iceland, supplying the population of Iceland with a large percentage of the tomatoes they need. The greenhouses are heated geothermally, but the lamps in greenhouses use electric energy. At the end of December or in early January the tomatoes are sown and subsequently planted out inside the greenhouses. The plants are planted out on rock wool, sod or pumice and cultivated in limited space. These twining plants grow up along wires that support them. Bumblebees are used to fertilize the plants, using their natural instinct to gather nectar and pollen.
Fossil plants - what do they tell us? Plants are preserved in the Earth's crust in various ways. Often a compression is formed when a plant or its parts are buried or covered in sediments. Types of sediment matrices include shale, sandstone, volcanic ash and diatomaceous earth. Delicate leaf and other plant tissue material showing the anatomy of ancient plants are of great interest to paleobotanist. Coal is an important type of preserved plant material. Coal is formed under substantial pressure. Detailed investigation shows coal to be composed of spores, wood fragments, bark fragments, cuticles and resins. Plants growing in regions where sediments are accumulating could become future fossils. Water, whether fresh, brackish or marine also often provides conditions for fossil formation. The geological record in Iceland shows that birch forests were widely spread during two periods within last ten thousand years, while wetlands, with characteristic sedges were more widely spread during other periods.
Green tabloid: The concerned citizen Many people around the globe are already devoting efforts to improve the planet’s wildlife and natural environment. Your contribution may be as simple as planting a native tree or shrub in your backyard. If you choose this approach, please, choose your tree varieties with care. Also, make sure forests, orchards and old trees are not destroyed without a reason in your neighbourhood. Another simple step you can take is to be more active in the recycling efforts in your community. Work against the incineration of rubbish, known to produce poisonous fumes. Help put the small jewels of nature on the map, with signposts, environmental art and maps of important places and landmarks. Encourage open areas with natural and semi-natural vegetation to benefit wild animals, such as birds and butterflies. Educate yourself about the environment, by reading more and considering some active positive steps you can take to improve the environment. Look after you local waterways, riverbanks, and beaches and consider participating directly in clean up efforts where they are needed. Emphasize repairing, replacing and redecorating, as just buying new things has a higher environmental cost. Finally you can move to the next step of trying to influence the decisions of your local government.
