Timber and farming creates big profits for some people, so deforestation is hard to stop. The practice damages biodiversity in one of the most biodiverse ecosystems on Earth.

Explanation:

Deforestation is the process by which a large track of the Brazilian Amazon rainforest is getting depleted as form 1970 about more than 700,000 km square of the forestland have been destroyed and damaged by the malpractices of cutting trees and that is about 87% of the original forestland. Causes are cattle ranching and grazing of the wild animals. Making of the infrastructure and building constructions, mining activity, and the soybean plantation. Apart from all this, the large scale rise of global warming processes is also responsible for the destruction of the forests. These are both threatening to the biodiversity and the local inhabitant of the lands. Creating pollution and the land degradation, hence affecting the water supply.

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
