Environmental Impact: Waste, Soil, and Risks

Types of Waste and Environmental Impact

For developing countries, the materials that we generate can be very useful.

Classification of Waste Materials

• Types of waste: Solid waste shall refer to the trash from homes and businesses.
• Non-urban solid wastes include those from industry, agriculture, and mining. These are: industrial waste, inert debris, and remains of mining operations that can contain toxic elements.
• Hazardous waste: These have highly hazardous components for health.
• Agricultural wastes: These are generally from activities in agriculture, livestock farming, and fishing.
• Medical and laboratory wastes: Remnants of the material used in hospitals and laboratories.
• Radioactive waste: This means materials that emit radioactivity.

Soil as a Vital Ecological Substrate

Soil erosion and pollution play a vital ecological role by serving as a substrate for plants and incorporating the necessary mineral elements for development.

Erosion and Soil Contamination

It is called soil erosion when there is a loss of the surface layer, rich in organic matter, by the effect of wind or rain. The contamination of the soil is important in itself and because, from the soil, contaminants pass into aquifers, rivers, seas, and oceans, as well as into subsoil layers. Most pollutants were related to chemical compounds used in agriculture as fertilizers and pesticides.

The mineral salts used as fertilizers in agriculture have led to progressive soil salinization. Deposits of hazardous waste and heavy metals provide certain atmospheric pollutants, which have also caused soil acidification.

Desertification and Deforestation

Desertification: The transformation of fertile areas that are relatively wet into dry, unproductive areas, with the subsequent loss of soil and main vegetation. The immediate cause of desertification is caused by water erosion on land denuded of vegetation.

Deforestation: The loss of forest is one of the main causes of destruction of biodiversity and is responsible for part of the climate change. The causes of deforestation have been the consumerist habits of developed countries and the economic requirements of underdeveloped countries.

Understanding Environmental Risks

ITEM 7! Risk: Every circumstance or situation that would result in damage to persons or property that can lead to a success. The risks, therefore, are the result of nature and humanity.

Factors of Environmental Risk

• Danger: The probability of an incident.
• Value of the affected area or exposure: It expresses the number of people living in an area or the ecological, economic, or cultural value of an area.
• Vulnerability: This is the percentage of victims and foreseeable damages.
