Air pollution Air pollution is the introduction of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or cause damage to the natural environment or built environment‚ into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s

The subject of deforestation and the effects that it has on the environment have been heavily debated for a long time; particularly over the last few years. Governments and large lumber companies see large profits in the mass deforestation of forests and state that their actions are having few‚ if any‚ harmful effects on the environment. Most people disagree with this and think that the environmental effects are devastating and will become irreversibly disastrous in the very near future. Whether

My project was over the tropical rainforest biome. The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50-260 inches (125-660) cm of rain falls yearly. A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100-300 species in one 2 ½ acre area in South America. Seventy percent of the plants in the rainforest are trees. There are a couple of topics that can be discussed within this biome such as

Mediterranean Scrub Introduction: Regions of Mediterranean-type climate occur roughly between 30° and 40° latitude on the west coasts of continents‚ where offshore there are cold ocean currents. Each region in which the Mediterranean shrublands and woodlands occur is island-like in character and thus there is frequently a high degree of endemism. Comparative studies of the several regional expressions of this biome reveal interesting examples of convergent evolution in plant families and birds (but

HISTORY AND CLASSIFICATION OF BIRDS The problems of classification of birds Has gained the attention of ornithologist and many systems have been proposed in order to establish their lineage until the beginning of the 19th century. The problem was solved in a rather over simplified way by using only significant characters especially external life forms and way of life and diet. Thus these birds whose toes are joined by welds where grouped in the natatoes. Those with long legs in the gralatories‚

Earth’s forests. Each year‚ strips of forest equivalent to the size of Panama are cut down and cleared. If these mass clearings continue at the rate they have been‚ all of the rain forests across the globe could cease to exist within one century. One major cause of deforestation is agriculture. When farmers need more room to plant crops‚ or more space to graze their livestock‚ they cut acres of forests down to accommodate themselves. Sometimes‚ small farmers clear away trees in the forest to feed

World’s Biggest Trees Are Dying Many of the world’s oldest trees‚ that are 100-300 years old‚ are dying. This is a trend happening worldwide. It’s happening in forests‚ savannahs‚ woods‚ mountains‚ cities‚ etc. The cause is human domination. We’ve been killing off these trees with pollution‚ deforestation‚ and other causes. This could really affect the world because other plants and animals depend on these trees for life‚ whether it be for food‚ shelter‚ or other needs. Large‚ old trees provide

emergent layer which has giant trees growing from 100 to 240 feet tall. These trees have umbrella-shaped crowns that grow high above the rest of the forest. They have their own distinct plant and animal life. The next layer is called the canopy. These trees grow up to 130 feet tall‚ and they form a tight canopy‚ or covering‚ over the rest of the forest which allows very little sunlight to come down. The branches and trunks of these trees are covered with smaller plants and appear to be tied together
