It is known that there are nuisance animals that live in dirty places and many people avoid cockroaches because they are disgusted or afraid of cockroach pee which can injure the skin because many people have experienced it.
Cockroaches are tough animals and can withstand nuclear radiation. This is evident during the tragedy of the Hiroshima and Nagasaki bombings in Japan during World War II, the only animals that can survive are cockroaches. This is because there are sensitive living cells in the cockroach's body that are dividing.
It is known, cockroaches are able to fart within 15 minutes. To make matters worse, the farts released by the cockroaches contain methane. If calculated on a global scale, methane from insects (especially cockroaches) can cause global warming. What is unique is that cockroaches can fart even though they are dead and survive until they fart for 18 hours.
In a year, it is estimated that a cockroach can produce 35 grams of methane gas from its body. It is quite small, but when compared to the small weight of a cockroach, this figure is roughly 43 times its body weight.
Methane gas is a component of greenhouse gases that causes climate change due to global warming. Compared to other greenhouse gases such as carbon dioxide, it has 23 times the power to make the earth warmer.
This fact places cockroaches as one of the biggest contributors to global warming. Other major contributors are termites and cattle.
