At present‚ approximately 60% of the study area (Jafarabad region of Golestan Province‚ Iran) has changed in recent years from forest to agricultural land and subsequently runoff and soil erosion have increased. However‚ the impact of this conversion on parameters of soil quality is unknown. The present study evaluated the influence of different land-use types on soil physicochemical properties in loess soils

Whether it is from precipitation‚ water washing over the land‚ car washing or watering crops or lawns‚ it picks up an array of contaminants including oil‚ sand and salt from roadways‚ agricultural chemicals‚ as well as nutrients and toxic chemicals from both rural and urban areas. Those are a few major contributing

The different types of pollution that affects our oceans are oil spills‚ dumping‚ sewage‚ agricultural runoffs and sunscreens worn by beach goers and swimmers. Pollution in the ocean is

As per U.S. EPA estimates‚ every year in the U.S‚ 1.2 trillion gallons of sewage from households‚ industries‚ and restaurants is dumped into U.S. waterways. Urbanization‚ agriculture‚ and sewage discharge are major contributors in the loss and degradation of North American wetlands‚ resulting in an increasing amount of pollutants in the waterways. A wetland is an area of land where the surface is partially or entirely covered by water‚ and is especially important in maintaining an ecological balance

My plan for sustaining cleaner fresh water in our lakes‚ streams‚ and rivers is to start by educating our community. In order to accurately educate the community to the issue at hand‚ I will first start by performing in-depth research on the pollution to the local waterways. Of the waterway pollution problems in our area‚ our largest concern is with wastewater and surface runoff issue. Due to all of the various

reefs. One of the major factors that cause coral reefs to decay is pollution. In coastal areas new development and landscape can cause runoff. The runoff can include excess nutrients‚ sewage outflows‚ and other pesticides from agricultural areas. These pollutants can reduce the oxygen levels of the water which leads to a decline in coral growth and reproduction. The runoff can also cause different types of coral diseases. Another type of ocean pollution is marine debris. Marine debris is trash that is

Water covers about 71% of the entire earth surface‚ yet despite its abundant deposit it is not readily available for use because of pollution especially due to human activities such as industrial‚ domestic and agricultural activities.

With an annual growth rate of 1.8%‚ three people are added to the Earth every second (Agriculture and Agri-Food Canada). This depicts the constant substantial population growth‚ which creates a deficit in the supply of nourishment annually. Accordingly‚ agricultural methods such as slash-and-burn‚ the aid of chemicals‚ and monocultures have followed as to increase

Phosphates are present in fertilizers and laundry detergents and can enter the water from agricultural runoff‚ industrial waste‚ and sewage discharge (Outwater‚1996) . Phosphates‚ like nitrates‚ are plant nutrients (Phosphates‚ 1997). When too much phosphate enters a water‚ plant growth flourishes (Phosphates). Phosphates also stimulate the growth
