Mangrove Forest in India Mangrove forests are one of the most productive and bio diverse wetlands on earth. Yet‚ these unique coastal tropical forests are among the most threatened habitats in the world. They may be disappearing more quickly than inland tropical reinforests‚ and so far‚ with little public notice. Growing in the inter-tidal areas and estuary mouths between land and sea‚ mangroves provide critical habitat for a diverse marine and terrestrial flora and fauna. Healthy mangrove forests

process called photosynthesis. This converts light energy into the chemical bond energy of carbohydrate which is utilized as cellular energy‚ plant growth and development. Water‚ carbon dioxide‚ nutrients and minerals are also needed for survival. In wetlands‚ where stagnate water contains acidic compounds and chemicals from decaying organic matter many plants have a difficult time obtaining necessary nutrients. It is in these nutrient poor conditions that some plants evolved different ways of obtaining

Victoria Perez The Control of Nature Response Paper It is an extremely difficult task for engineers to design a “dam” like the Old River Control Structure in southern Louisiana so that they can be sure that it will prevent avulsion of the Mississippi into the Atchafalaya. The flood of 1973 that caused so much damage to the Old River Control Structure was the affect of many things. There were unusually heavy snows in the upper valley. The South of the state received an exceptional amount of rainfall

recycling protects wildlife habitat and biodiversity. Using recycled materials reduces the need to chop down‚ extract‚ process‚ refine and transport natural resources such as timber‚ crude petroleum and mineral ores. As a result‚ destruction of forests‚ wetlands‚ rivers and other places essential to wildlife is also reduced. One more fact‚ that recycling lowers the use of toxic chemicals. Making products from already refined waste materials reduces -- and often avoids altogether -- the need for

Today’s modern world has led to the biggest problem faced in history: global warming. Today’s fast-growing industrialized economy is causing serious environmental issues such as extinction of much of the life on this planet‚ temperature changes‚ and sea level rise. One simple way of reducing the effects of global warming is changing our way of living. One benefit of reducing the industrialized economy of today is that natural habitats will last longer.

method of disposal of solid waste by compacting it and burying it under a shallow layer of soil. The location of a sanitary landfill must take into account the geology of the area‚ soil drainage properties‚ the proximity of surface waters and wetlands‚ and distance from population centers. Despite design features such as high-density plastic liners and leachate collection systems‚ most sanitary landfills have the potential to contaminate soil‚ surface water‚ and groundwater.
