Assoli18 [71]

Agriculture is an activity that requires a lot of fresh water.

  • This is because agricultural crops need large amounts of water to grow and remain productive.
  • In a situation of large-scale agricultural production, this need for water is even greater, causing producers to use large quantities of water that is necessary for the consumption of the population.

<h3>Give the detailed explanation?</h3>

In order to conserve fresh water and keep it at high quality levels to be used both in agriculture and for human consumption, it is necessary that agricultural producers allow the maintenance of riparian forests, use more biodegradable pesticides or with low impact on nature and pay attention to irrigation equipment to avoid waste.

In addition, many producers waste water and pollute it with an excess of pesticides and deforestation.
