Since rain may be exposed to contaminants in the air or in the method of collection, it may be too "dirty" to drink. Rainwater is not generally suitable for use as drinking water without testing and possible treatment.Know More
Pollution, such as soot, smoke and dust, may be incorporated into rainwater as it falls through the atmosphere. In agricultural areas, airborne fertilizer residues may contribute a higher concentration of nitrates in rainwater. The method of collecting rainwater can wash molds, algae, bacteria and other organic matter into storage containers. It can be difficult to harvest a significant amount of rainwater safely without risking at least some bird droppings winding up in the rain barrel.
Harvesting rainwater for potable use is possible, however, and the first step is to test the water to make sure it can be easily treated. Rainwater harvesting systems are available that provide guidelines and equipment for safe collection, filtration and treatment of rainwater for drinking.Learn more about Environmental Science
Rain is needed as a source of fresh water, which is essential for the survival of humans, plants and animals. Rain fills aquifers, lakes and rivers, maintaining the lives of living organisms. Rain maintains natural features, such as forests.Full Answer >
An animal that eats bamboo in the rain forest is the golden bamboo lemur. Although the Giant panda and Red panda both feed on bamboo as well, these animals live in temperate bamboo and broadleaf forests, not tropical rain forests.Full Answer >
The Virtual Chembook of Elmhurst College explains that acid rain considerably increases the rate of corrosion on marble, sandstone and limestone buildings. Sulfur dioxide and water forms sulfurous acid, and sulfur trioxide and water creates sulfuric acid, which reacts with limestone in a neutralization reaction. Limestone dissolves and crumbles as calcium sulfate is soluble in water.Full Answer >
Several chemicals cause acid rain, although sulfur dioxide and nitrogen oxide are the primary contributors. Sulfur dioxide and nitrogen oxide contribute largely to the development of acid rain, although several natural sources, such as volcanic eruptions and decaying vegetation, cause acid rain as well.Full Answer >
