Concept:Pests destroy crops and stored food, so pest control reduces the food losses that cause shortage.
Explanation:Pests are organisms such as insects, rodents, and birds that feed on agricultural produce.
They attack crops on the farm and stored food, reducing the quantity available to people.
Heavy pest damage lowers food supply and deepens the problem of food shortage.
Efficient pest control services protect crops and preserved produce from destruction.
As a result, much of the farm output is kept safe for feeding the population.
Natural hazards destroy farmlands, while illegal exportation takes food out of the country.
Hoarding also keeps food off the market and creates artificial scarcity.
Therefore, controlling pests effectively helps to minimize food shortage.
