Geobiology is the study of how living things (like plants, animals, and humans) interact with the Earth (the ground, water, air, and other parts of the environment). But pseudoscience means that some people believe in things that haven't been proven to be true by science.
Some people who practice geobiology believe that the Earth gives off special energy that can affect people's health, happiness, and success. They think that there are good and bad energies in the Earth, and that certain places (like where lines cross in the ground) have more of the good or bad energy. They also think that wearing certain crystals or using certain tools can help protect you from the bad energy or bring you more good energy.
However, many scientists do not believe that there is any scientific evidence to support the claims that geobiology makes. They think that people who believe in it are simply looking for something that is not there. Instead, scientists believe that people's health and happiness are affected by things like their diet, exercise habits, and mental health, rather than by any supernatural energy from the Earth.
In short, geobiology is an idea that suggests that the Earth's energy can affect human health and well-being - but it is not supported by science and is often considered to be pseudoscience.
