Disadvantages of Using Natural Predators:
Using natural predators takes a lot more planning, and requires a great
deal of patience. People in charge of it need to be more educated, which makes salaries of staff have to increase. In some
cases it can also be more expensive. Introducing natural predators also takes time, and is not an instant fix like pesticides.
Disadvantages of Using Pesticides:
Many plants and animals are affected by chemicals used
as pesticides that we use in our everyday lives. Although we may be decreasing pests devouring our plants and crops, but we
are also putting them in danger. . For example DDT can affect rare existing animals such as eagles, causing them to inhale
the harmful chemical or feed off the plants and water. Eventially , it can cause the birds eggs to lose calcium causing them
to weaken and break, therefor decreasing the eagles population. Harmful chemicals can also affect humans, through inhalation
and through the food we eat, which contains the pesticides we used in the first place to “protect” them.
