Whether you believe Global warming or not, changing environment doe shave local impact. If your country is passing through so called “Development” bandwagon, you are prone local rapid environmental changes. Rising temperature is one such outcome.
Reading two research papers back to back gives enough future predictions. Rising temperature does not only cause damage to insects! We are equally affected! Read two researches and connect the dots!

GLOBAL WARMING DAMAGES SYMBIOTIC ORGANISMS
The collaborative work is described in a recent study published online in the journal mBio, a journal of the American Society for Microbiology. Experiments showed that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted. The research illustrates another way global warming will wreak havoc on life as we know it, setting off deleterious chain reactions among organisms living in symbiosis.
Specifically, the investigators demonstrated that when the southern green stinkbug was reared inside an incubator, in which temperature was controlled at 2.5 °C higher than outside, there was a significant reduction in the symbiont bacteria that sparked severe fitness defects in the insect (ie. retarded growth, reduced size). At higher temperatures, no nymphs were able to reach the adult stage. Global warming is predicted to raise the average temperature by 2.5 °C by 2100.
“Considering that many microbial symbionts are vulnerable to high temperature stress, such symbionts can be the Achilles’ heel of symbiont-dependent organisms in this warming world,” said Dr. Fukatsu. He said that people should keep in mind that global warming might impact diverse organisms, not necessarily directly, but possibly indirectly via affecting unseen microbial associates. “Coral breaching, in which symbiotic photosynthetic algae of corals are killed by high temperature and coral reefs are severely damaged, is regarded as a serious environmental issue, but plausibly, similar phenomena may be ubiquitously found in the ecosystem,” said Dr. Fukatsu.
