Harmful insects include aphids, whiteflies (eat our crops), mosquitos (carry disease), fleas and lice (suck blood). However, the insects that eat our crops mostly only do so because we practise too much monoculture and kill off their predators with insecticide. The herbivores such as aphids and whiteflies reproduce fast enough to build up resistance, whereas their predators such as ladybugs do not.
Useful insects include those ladybugs (eat aphids etc), parasitic wasps (kill many harmful insects), and bees (pollinate plants and make sure they can reproduce and bear fruit).

Soap can be harmful to insects because it can disrupt their outer protective layer, causing dehydration and ultimately leading to their death. Additionally, the chemicals in soap may interfere with insects' respiratory systems or digestive processes, further harming them. It is important to use soap products carefully and in moderation to minimize their impact on insect populations and the environment.

Natural gas is useful as a relatively clean-burning fossil fuel that can be used for heating, cooking, and electricity generation. However, its extraction and transportation can result in methane leaks, a potent greenhouse gas, contributing to global warming and climate change. It is important to balance the benefits of natural gas with its environmental impacts.
