Many orthopteran populations are currently in decline due to several significant environmental threats. According to research on the ecology of this insect group, the primary drivers of these population losses include:

Global warming: Changing climate patterns disrupt the environmental conditions necessary for the survival and development of many species.1
Habitat loss: The destruction and fragmentation of natural environments reduce the availability of essential shelter and resources for these insects.1
Broad use of insecticides: The widespread application of chemical pesticides poses a direct threat to orthopterans, as these substances can contaminate their environments and negatively impact their health and survival.1

Protecting these insects is an ethical imperative, as they are vital to the health and functioning of their ecosystems, serving as key herbivores, food sources for various predators, and, in some cases, important pollinators.1
