Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate.Colostrum is the first stage of breast milk.

Any natural substance that humans use can be considered a natural resource. Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water.Inorganic Contaminants and Wastes
Inorganic Contaminants and WastesInorganic compounds may consist of heavy metals and toxic elements (e.g., lead, mercury, chromium, arsenic, etc.) in pure form or combined with other elements. These compounds exist primarily in the solid phase, but can also exist at ambient temperatures in the gas phase if finely divided or have a high vapor pressure (e.g., mercury, hydrogen sulfide) or the liquid phase if water soluble. In general the undesirable (e.g., toxic or hazardous) nature of these compounds stems from the element(s) they contain rather than their structure. Therefore, the undesirable in most inorganic compounds cannot be eliminated by oxidation or thermal decomposition of those compounds. Notable exceptions include compounds such as hydrogen sulfide (H2S) and ammonia (NH3), which when oxidized become far less toxic.
