Environment is affected by the interactions among humans, flora, fauna, and their physical surroundings. Intensive human intervention on earth has changed environmental conditions and caused environmental hazards such as: air pollution, water and ground pollution, damage to biodiversity, and accumulation of toxic waste.
Air pollution is a process in which matter generated by human activity and natural sources penetrates the atmosphere in concentrations that are hazardous to humans and the environment. The main sources of air pollution are: fuel combustion from motor vehicles and industries, industrial processes such as production of cement and landfills that emit gases produced by the decomposition of organic matter. These sources, among others, cause greenhouse gases to be emitted, which lead to global warming and to climate changes.
Israel faces difficult challenges related to the amount and quality of water that is suitable and available for use in agriculture, industry and households. There are various indices for testing water quality, including concentrations of nitrates, turbidity, and salinity (chlorides). In Israel, the permitted standard of chlorides in drinking water is 600 mg. per liter. By contrast, the standard permitted by the World Health Organization is only 250 mg. per liter. The main water sources in Israel are the Coastal Aquifer, the Mountain Aquifer, and the Sea of Galilee.
Recycling is a process of removing material from the waste flow and using it as raw material or to create new products. This process diminishes the use of natural resourses and contributes to saving energy and reducing pollution.
