Solar energy, a natural source of energy from Sun, has been harnessed by our ancestors since ancient times by means of various technologies. This is one of the most available renewable energy on Earth. But only a minor percentage of this energy is used.
Heat engines and photovoltaics help in the generation of electricity. The uses of solar energy are limited only by human initiative. Solar hot water, solar cooking, daylighting, etc. include in the partial list of solar applications. Generation of energy from Sun is either direct or indirect. There are many technologies involved in each.
The use of renewable resources on energy like Sun, wind will bring a great solution to the existing power crisis in many of the remote places in the country.

Deforestation

Sat, 28 Nov 2009 08:50:05 +0000

Deforestation, the main cause for the devastation of our biodiversity, has been practising for many years. But today’s worrying factor is the massive destruction of rainforests.
Trees play a vital part in environment, animals, and humans. They act as filters of carbon dioxide. Trees and vegetation are being destroyed to make room for housing and businesses. Statistics says that more than 50 percent of the tree population has disappeared due to human activity.
The adverse effects of deforestation are erosion of soil, disruption of the water cycle, loss of biodiversity, flooding and drought, and climate change.
We citizens can try to prevent deforestation by many small simple ways. We can plant some saplings in our own garden. These will give oxygen and protect against soil erosion. Recycling of books, papers, bottles, cans, shopping bags also helps. Crop rotation also helps.
Trees are valuable resources. They provide food, oxygen, shade, and beauty.
Let us all join together and make some efforts to prevent their destruction to save a healthy environment for next generation!

‘Also go for fatty fish, which have dark flesh (muscle), as the depth of color reflects the amount of oil present in the flesh. Lean fish is pale, thus it’s fat in concentrated in the liver, instead of muscle. Usually, it’s the cold-water fish that is fatty, such as tuna, salmon and trout,’ she says. Common local varieties-include hilsa, singhara, katla, puruva, and seer.
