Despite their historical resilience, insect populations are now facing a severe decline due to human-induced factors such as habitat loss, pesticide use, and climate change.
This is the primary argument for why insect populations are collapsing. It is not something I will be arguing with as it is generally accepted as the reason across every professional paper I've read on the subject. But it is good information to have.
Insect conservation strategies include habitat conservation and restoration, sustainable land management, species-specific conservation, and policy and legislation. Habitat conservation involves identifying critical habitats, restoring damaged areas, creating insect-friendly spaces, and establishing protected areas.
Various theories on how to help solve the problem
Thus, as pollinators decline, the availability and variety of fruits, vegetables, and nuts could be significantly reduced. This not only affects our diets but also disrupts the livelihoods of farmers who depend on pollination services for their crops [07]. Aizen et al. [91] revealed that a complete loss of pollinators could reduce global agricultural production by 3–8%, requiring a significant increase in cultivated area to compensate, particularly in the developing world
The argument I specifically want to talk about is how their decreasing population impacts us. My main audience is going to be both people who may not believe in these issues and people who aren't educated on them. Or doesn't believe it matters because it doesn't impact them. So specifically arguing how it can and most likely will affect them will be my main goal.
insects have advanced numerous fields by serving as model organisms for scientific studies.
More information on why they are beneficial for us. Could maybe use this for more background information, or just information to help convince an audience.
Moreover, the diversity of insects is complicatedly linked to the diversity of plants [8, 13, 14]. Over time, insects and plants have coevolved, establishing complex relationships such as pollination and herbivory.
Good quote showing how certain insects and plants are linked in their ability to sustain.
Insects make up 75%–80% of all known animal species, with estimates ranging from 10 to 30 million, of which approximately 1.11–1.7 million are described.
Talking about just how large a percentage of all animals insects take up would be a nice piece of background information for those who may not know.
