Question

Find the flaws within the sentance/s

Extinction is the complete disappearance of a species from Earth. A mass extinction is when more than half of all extant species disappear from the fossil record and there have been at least five of them.

In order to prevent the extinction current species, some areas of earth are preserved while others are conserved. Conservation seeks to prohibit human activity in an area. Preservation seeks the sustainable use and management of natural resources.

An endemic species is only found in one location. A biodiversity hotspot has over 1500 species of endemic insects and 70% of the area has been disturbed. There are 34 biodiversity hotspots on Earth.

Many sustainable practices are used in agriculture. Crop rotation is the practice of growing different kinds of crops in the same area in sequenced seasons. Conservation tillage is any method of soil cultivation that completely tills under the soil to prepare for the next crop. Genetically modified crops are crops that have been modified to be more nutrient dense, grow larger fruits, be herbicide resistant, or pest resistant.

Abiotic factors of habitat restoration include soil chemistry, water content, and general disturbance. For example, restoring stream flow or modifying elevation. Biotic factors of habitat restoration include returning species to improve species composition and interactions among species. For example, planting native plants or releasing native animals.
