Answer 1

Ans) 1) a. Crop rotation

Explaination:

- Crop rotation is also used to control pests and diseases that can become established in the soil over time. This principle is of particular use in organic farming, where pest control must be achieved without synthetic pesticides.

2) Agent orange

Explaination:

- In its production, it releases dioxins, phthalates, vinyl chloride, ethylene dichloride, lead, cadmium and other toxic chemicals. It can leech many of these harmful chemicals into the water or food it's being used to contain, which is how those chemicals get into our bodies.

- The chemical dioxin in Agent Orange can remain toxic in the soil for decades. . After its use in the 1960s, Agent Orange was banned by the U.S. in 1971 and remaining stocks were taken from Vietnam and the U.S. to Johnston Atoll, a U.S. controlled island about 700 miles SE of Hawaii, where it was destroyed in 1978.
