Agriculture negatively affects reef ecosystems because the soil and the sea have a direct interaction of substances and minerals that can be altered with the intensification of agriculture.
<h3>What is agriculture?</h3>
Agriculture is a human activity that is based on planting seeds in the ground so that they develop and form plants that have uses such as food or others.
This is one of the oldest activities of humanity and has allowed communities to develop and create trading systems, wooden constructions, navigation, among others.
<h3>What impact does agriculture have on the reefs?</h3>
Agriculture generally takes place in coastal areas or near rivers because the composition of the soil must have certain minerals necessary for plants to grow.
Additionally, the components of the soil go underground to the sea and provide the water with different substances that contribute to marine life. However, the use of pesticides and other agricultural chemicals could reach the sea through runoff and affect the reefs.

A saturated fatty acid is a basic unit of lipid that consists of only single carbon to carbon bonds.
Saturated fatty acids have been “saturated” with hydrogen ions and only have single carbon to carbon bonds, unlike unsaturated fatty acids that have both single and double bonds and have kinks and aren’t straight.
Saturated fatty acids are solid in room temperature(animal fats) and unsaturated fatty acids are liquid in room temperature(oils/plant fats).
