Answer 2

first of all as you can hear from the name there are chemicals in them. and majority of the time, the chemicals are extremely harmful to our envoronment. as been heard lately, we are already having problems with the environment... so why add to the problem?

secondly, the pesticides leave toxic residue... in other words they leave toxic materials on wherever or whatever they are applied on. this means that if the pesticides are applied on a field that is growing crops... the toxic materials will be left back on the crops...imagine eating toxic materials!!!!

it is harmful to animals and humans when taken in....

overall, they are very bad...why use these pesticides when there is a safer alternative... biological pesticides!!!!

be smart... do not use chemical pesticides....use biological pesticides!!!!!!!!!!!

Please note that this is just a basic answer.

Chemical fertilisers are advantageous as they encourage growth in the intended plants. However, they are detrimental as they also stimulate growth in plants which they are not intended for and may also be toxic to other life including humans.

Answer 4

There's advantages and disadvantages of the use of natural pesticides

The use of natural biological control can have an a positive outcome on our world. When we use everyday species that exist in the world today, we eliminate the need for using hazardous chemicals on our crops. This in turn, can prevent chemicals from damaging the environment and organisms. It helps to preserve the environment for generations to come. On the overhand, 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. Eventually , it can cause the birds eggs to lose calcium causing them to weaken and break, therefor decreasing the eagles population.
