It is a serious environmental concern since it harbours many health hazards.

- Solvay proposes solutions for reducing air, water and soil pollution.
- Air, water and soil pollution have already caused substantial modifications of the climate and in the natural environment of the planet.
- In the industrialised countries, the wooded area has remained relatively stable, but forests are slowly dying from air, oil and soil pollution.]]> 2022-09-08 19:46:19 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288794658 Soil degradation dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288799155 Soil degradation is the decline in soil condition caused by its improper use or poor management, usually for agricultural, industrial or urban purposes. It is a serious environmental problem. Soils are a fundamental natural resource, and are the basis for all terrestrial life.

- Erosion is probably the most common type of soil degradation in the world.
- The current rate of soil degradation threatens the capacity of future generations to meet their food needs.
- Companies follow guidelines to extract timber responsibly, reduce impact on forest ecosystems and help reduce land and soil degradation.]]> 2022-09-08 19:50:23 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288799155 Agriculture dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288802294 The science or practice of farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products.

- In agriculture, Viet Nam has promised not to subsidize exports.
- The property understands 24 hectares exploited in agriculture of conservation.
- Many countries have large populations that depend on agriculture.]]> 2022-09-08 19:53:20 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288802294 Primary salinity dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288804530 Primary salinity is caused by natural processes such the accumulation of salt from rainfall over many thousands of years or from the weathering of rocks.

- They can live in sandy soils, even with high salinity.
- It is sensitive to the salinity of irrigation water.
- It also resists quite well to the salinity of the soil.]]> 2022-09-08 19:55:28 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288804530 Secondary salinity dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288808505 Secondary salinity is salting that results from human activities, usually land development and agriculture.

- The density of water is affected by temperature and salinity.
- Until the 1970s the salinity had been almost constant.
- It automatically collects various ocean data, such as salinity and temperature.]]> 2022-09-08 19:59:08 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2288808505 Irrigation dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2308170930 The supply of water to land or crops to help growth, typically by means of channels.

- The land is flat with a pool, irrigation and lawn. 
- The garden will be landscaped with an automatic irrigation system.
- It is used for irrigation with a continuous and powerful flow.]]> 2022-09-22 06:19:30 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2308170930 Dryland salinity dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2308191632 Dryland salinity is a natural process for soil, just like other processes such as wind erosion. Salinity degrades land by an increase in soil salt concentration in the environment, watercourse or soil in unirrigated landscapes, being in excess of normal soil salt concentrations in dryland regions.

- The salinity of drylands damages the environment too much.
- Dryland salinity is a very interesting process in nature.
- The salinity of drylands, despite being a natural process, at the same time damages part of nature.]]> 2022-09-22 06:34:37 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2308191632 Desertification dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2308193658 The process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture.

- We cannot burn it without causing desertification and climate change.
- Djibouti recommended a systematic approach to combating desertification.
- Millions of trees were planted in an attempt to stop desertification.]]> 2022-09-22 06:36:14 UTC https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2308193658 Fertilizers dayana_ssaucedo https://padlet.com/vunidadinglestec/kyylp1ep5mc2qptp/wish/2309553019 A chemical or natural substance added to soil or land to increase its fertility.

- This crop requires high applications of chemical fertilizers, particularly nitrogen.
- Some children are especially sensitive to fertilizers, herbicides, or pesticides.
