1/ How did modern insect problem come to alarmingly threaten the very existence of humanity? (300)

The relationship between insects and human-beings is always seeking a delicate balance. Though it’s admitted that there’s a large amount of insects bring benefits to human, such as pollinator species, resource insects and even coprophagous that is addressed as cleaner insect, the number of pest insect is not within the scope that human could either tolerant or neglect. Pest insect acts as the notable enemy of forests, wood and fields, and also should be responsible for the widely spread disease. Recent years, with the rising temperature by globe warming, there’s a large possibility that insects would break up former habitat and turn to the journey for new activity spaces. In this way, the underlying threat caused by insects is lying in front of human-beings. The great harm that pests throw to human is presented specifically in two aspects, including insects themselves and the pesticide that aims to eliminate the pests, while which works to cause the opposite effect, making human themselves ultimate victims.

First of all, pests are often introduced by human activities such as trade, travel or import. It comes to that the developed country have the ability to observe the invasive species while the developing country is under higher risk of preventing the pests and control the danger. Because of the delayed detection and insufficient technology, the modern insect problem evolve into critical trouble which greatly threat the existence of humanity.

Secondly, the abuse and misuse of pesticides also plays an important role. With the governmental permission or even encouragement, farmers sprayed the pesticides as much as they think it’s enough to kill the pests bu t without the consideration of environment, while ultimately causes the destruction of environment, water and air is contaminated and what’s worse, the crops and food would bring human body unimaginative harm.

In summary, on the surface, it’s the pest and unscientific use of pesticide that are to be blamed, while let’s get to the bottom of it, it’s human-being themselves to reap the fruits of their own action.（335）
