Tree shade also helps cool municipal buildings‚ lowering electricity bills. 3. Trees cool our cities. Urban "heat islands" are directly related to massive tree-cutting for development. 4. Trees clean our water and air. From low level ozone in our cities to pesticide and fertilizer runoff from our farms‚ trees absorb harmful pollutants. 5. Trees help community

Trees filter sewage and farm chemicals‚ reduce the effects of animal wastes‚ clean roadside spills and clean water runoff into streams. 3. Trees Control Noise Pollution Trees muffle urban noise almost as effectively as stone walls. Trees‚ planted at strategic points in a neighborhood or around your house‚ can abate major noises from freeways and airports. 4. Trees Slow Storm Water Runoff Flash flooding can be dramatically reduced by a forest or by planting trees. One Colorado blue spruce‚ either

The Consequences of Water Pollution Annually‚ 90 million people add to the current population of 6.5 billion. At this rate the global population will reach approximately 8.5 billion by 2025 (http://dieoff.org/page120.htm). As the global population grows exponentially‚ so does the demand for natural resources. Of all these natural resources‚ water‚ is the most vital for survival and expansion. Human’s dependency on water will never go away‚ making it a key part to any civilizations future. It

Unfortunately various forms of pollution‚ including runoff and erosion‚ can interfere with the health of the watershed. Therefore it is important to protect the quality of our watershed. It is important for the people to be aware of the events that happen around them‚ especially the information that concern

These may be collected by rainwater runoff and carried into steams‚ rivers‚ lakes‚ and even into the ocean. More than 14 million Americans drink water contaminated by with pesticides.
