Afforestation

Earth Day 2009, April 22, will mark the beginning of The Green Generation CampaignTM which will also be the focus of the 40th Anniversary of Earth Day in 2010. With negotiations for a new global.

First a short bit on what polyethylene is:

Polyethylene is a long chained organic molecule that is formed from ethylene (H2C=CH2).It contains no other materials than Carbon and Hydrogen. The basic building block (ethylene) is a non toxic gas that can act as a hormone in plant growth, speeding ripening and the rowth of seedlings.

The harmful effects of polyethylene are more related to the forms that it is made into - films, ropes, six-pack holders, milk jugs etc. As trash it is refractory in the environment, lasting for many years without decomposition except if it is exposed to sunlight. As trash, due to its shapes it has been observed to trap animals legs and heads.

If collected it can be easiiy recycled reducing the need for consumption of fresh raw materials and energy. If burned, it is converted to carbon dioxide and water.

When you say historical, I am compelled to think of both document and event. So I shall provide an example in both situations. In the Congress of Vienna of 1815, where the Restoration of Europe began, the most important principle was legitimacy. Conservatives aimed to make legitimate both the monarchy's authority and a hierarchical social order. Conservatives wanted political stability after a period of turmoil with the French Revolution and other events of the time. And legitimacy seemed to be the best way to ensure that stability when restoring the government systems in European countries. As for the document, Edmund Burke's Reflections on the Revolution in France is a clear example of conservatism. He argued that the "conquering power of reason" was dangerous. He also saw enthusiasm for constitutions as misguided (as enthusiasm was in the French Revolution with the Reign of Terror). In his document, Burke defended experience, tradition and history.

The most important source of carbon entering atmosphere is industries. Living things, burning fossil fuels and automobiles are other sources of carbon dioxide.

A.

conserve water resources

B.

reduce air pollution

C.

increase fuel efficiency

D.

protect marine species from overfishing

Businesses can cut their energy use by ensuring that their equipment is up-to-date and efficient. They can educate their staff to turn off lights and heating when not needed. Businesses should get a proper energy consultant to evaluate their energy usage and make thorough and specific recommendations for their industry sector.

some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...

Are the rocks,boulders,stones ect. That has been weathered over a certain geological period of time ,breaking down the rocks,boulders ect into smaller rock particles and then into smaller rock particles until they become the soil

1. Educate children from the early age about earth nature and environment.
2. Join tree-planting clubs and other nature and ecology clubs.
3. Make them aware of the relationship of man and nature
4. Promote afforestation via tree plantations-involve parents and teachers along with children
5. Display banners explaining disadvantages of deforestation for e.g. land sliding, impact on wild life, global warming

Man and environment reciprocal relationship. The relationship between humans and environment has varied from the early periods of human settlement on the earth to the present day. The relationship between environment and human beings has also being varying from place to place at any given period of time. For example, early humans considered the environment to be dominant. They were afraid of lightning and thunder, dense forests, wild animals, vast oceans and large rivers, to name a few. The environment has considerably affected human beings right from his evolution. The environment affects humans in many ways. Population on the earth varies due to variation in the environment. The main factors which affect the distribution of population and human settlement are: 1) Relief of Land The populations in the high mountainous areas, such as the Himalayas in India, Andes in South America, Rocky in North America, etc., have very low settlement level. This is because the relief is rugged here which represents obstacles in the construction of roads, railways and communication. Due to steep slopes, agriculture is done with a great difficulty and industries also could not be established. These places having very less economic activity have less population and hence have small isolated settlements. Whereas the plain areas of the world are most suitable for human settlement. Fertile plains of Ganga in India, Indus in Pakistan, Hwang-Ho in China and plains of Europe have huge population concentration having compact or huge semi-compact type of settlement. 2) Climate Most of the areas of the earth having density less than two persons/sq. km are not favorable for settlement because of their unfavorable climate. Areas of cold climate-North Siberia, North Canada, Alaska etc. have low density of population. Hot and arid regions of -Sahara, Kalahari Desert in Africa, Great Australian Desert etc are not suitable for human settlement. In tropical regions due to heavy rain and temperature, the density of population is very low, example in Amazon basin population density is less than two persons/sq. km. But places with favorable climate and favorable terrain, have dense population and hence have compact settlement. 3) Soils Fertile alluvial soils encourage dense population which in turn gives rise to compact type of settlement. This is so because alluvial soils give rise to agricultural activities. Java Islands of Indonesia has fertile soil of young volcanic material and agriculture is an important activity, hence dense and compact settlements are found here. Whereas in Sumatra, due to infertile soil, the population density is very low. 4) Mineral Deposits Mineral wealth is yet another factor responsible for population distribution and density. The presence of coal and iron-ore in different parts of the world has attracted huge population. Coal mining regions have become regions of dense population for example, Jharkhand in India and gold mines in Australian desert. 5) Water supply Population distribution is very much affected by water supply. The earliest settlements or civilizations developed on the banks of major rivers, example-Nile, Indus, etc. Adequate water supply provides irrigation facilities to farmers and hence population increases due to increase in primary activities. In dry regions, population is concentrated in those areas where there is water, hence nucleated- circular settlements are found. Thus it can be said that the environment plays an important role in deciding population distribution, density, settlement type and pattern. The Industrial Revolution which provided mechanical power, invention of steam engine and other machinery, greater use of metals etc gave them opportunities to modify the environment. At the same time agriculture provided abundant food so that they could settle down permanently. The family grew in size and people migrated to different parts, via rail, road and sea, because of improvement in transport system, example the new lands in America and Australia were settled by people from Europe. Another development which enabled humans to survive was the use of preventive and cumulative steps taken to protect them from epidemics and diseases-it increased the span of human life and reduced death rate. With increase in the knowledge and skill and development of human economy there was a gradual increase in carbon dioxide content. It is estimated that carbon dioxide content has increased by 25% in last 100yrs and the global temperatures have risen between 0.3 degree Celsius to 0.7 degree Celsius. Increase in carbon dioxide is attributed to large scale deforestation and will lead to increase in sea level causing submergence of coastal regions. Burning of coal, oil and petroleum adds sulphur dioxide to the atmosphere. Lead, carbon monoxide and nitrogen dioxide are added to the atmosphere from automobile exhaust. These gases result in acid rain which affects aquatic life, example acid rain in industrial regions of Europe and North America. Even now substances which were not present previously, are introduced into the air, water and soils. The most dangerous one is radioactive substance spewed into the atmosphere by nuclear explosions. They have adverse effects on organisms including man and cause death, impairment of limbs, diseases and psychological disorders. The catastrophe of nuclear disaster at Chernobyl in Ukraine (1988) is a burning example of adverse environmental effects of use of minerals like uranium, thorium etc. through most advanced and sophisticated technology. The environment has already been degraded to such an extent in certain areas that people are forced to migrate. They are facing scarcity of resources like food and energy. Man's impact on environment has resulted in pollution of environment which not only affects air, water and land but also organisms of biosphere. The main points summing up the impact of man on environment are: Air pollution-burning of fossil fuels in large quantities from jet aircraft, CFCs used in aerosol spray cans, refrigerators and farm blowing are responsible for depletion of ozone to 3-4% in last 100 years. Water pollution-leakage of petroleum from huge ships and oil tankers into the sea, causes oil slicks which spread rapidly over water and spell disaster to marine life and to human depending on marine resources. The leakage of 100000tons of crude oil near Spanish coast in 1976, leakage of crude oil off Alaskan coast in 1989 are a few examples of the many such incidents which tell the impact of negligence and failure of technology on environment. The most widespread source of water pollution is disposal of sewage of urban centers into rivers. The Ganga and Yamuna are polluted in this way and the same rivers provide domestic water supply as well. Ocean waters are polluted by discharge of sewage from cities located along the coast. Land degradation-dumping of solid waste from urban centers and waste materials from mining centers renders the land unsuitable for any use. Surface run-off from such areas pollutes streams and ground water seepage. Saline encrustation of irrigated lands is another example of land degradation. In the semi-arid region, wind action causes deposition of sand on a large scale over cultivated land rendering them unfit for cultivation. This marks the beginning of the process of desertification. Depletion of resources-population growth in the recent past has resulted in rapid depletion of all kinds of resources. The most striking example of such resource depletion is the food deficit faced by about 100 countries of the world. Forest and soil resources are getting depleted at a fast rate owing to population pressure. Tropical forests are depleting at a rate of 2% per annum. It is estimated that the world is losing 7% of top soil per decade. Depletion of resources is most significant in respect of non renewable mineral and power resources. The world is facing energy crisis as existing oil resources may last for a few decades. Though coal reserves are adequate for a few centuries but it cannot replace oil, especially for transport. Humans have come to realize that their economic activities are threatening their survival on earth. Their survival depends on their realization that they have to live in harmony with the various elements of environment which are interconnected. An understanding of the components and processes which take place in environment, the relationship between biotic and abiotic components, and the assessment of resources with reference to need of people in a region is essential for their survival.

Afforestation means planting more trees. This helps by -

1) It prevents soil erosion.

2) Planting more trees (afforestation) increases the amt. of oxygen in the air.

3) Trees have medicinal properties and we get various products such as wood, food, flowers, paper, etc, so we should follow afforestation and not deforestation!

I hope u understand my explanation and u plant more trees! :)

if there are less tress that means there is less oxygen so our children's children's children may not live and it also mean loosing more and more animals that live in forests and also means as we run out of tress there is going to be less and less paper from trees being produced so in conclusion they should carry on doing for every 1 tree they chop down they should plant another 2 :)))))))))))))))))))))))))))))))))))))))))

Afforestation is almost always a good idea. Trees remove carbon dioxide from the atmosphere, really the only way we can reduce greenhouse gas levels there. Trees have many other positive effects on the environment, being good for birds and animals as well as soil retention and stability.

India is known for its forest resources. But due to rapid exploitation of forests they are going to be seen as endangered ones. To protect trees, van mahotsav the tree-planting festival, is celebrated throughout India.

objective of afforestation in abuja

Afforestation is the opposite of deforestation. It can create habitats for wildlife and it stabilises the ground to prevent surface run off.it prevents soil erosion and the fields do not get barren and infertile.

Lightning strikes are the Number Two cause of forest fires. Human error is Number One. At one time, it was thought that forest fires are ONLY detrimental. That theory has evolved to reveal that forest fires clear out the underbrush & fertilize the forest floor so that the big trees like Redwoods, Bristlecone Pines, Junipers, Pinyons and other conifers may flourish.

clearing land for agriculture

We breathe in oxygen, and breathe out carbon dioxide, wheras trees breathe in carbon dioxide, and breathe out oxygen. As you should know, carbon dioxide is a green house gas, which contributes to global warming. Trees essentially absorb it, taking some of it from the atmosphere, helping prevent global warming.

there are too many ways to count but for one, when dead are buried it nurishes soil and provides food for animals. just think of us as animals (which we are). how do they affect the enviornment?
