What we need most - the plants

Det urgamla sättet att locka till sig något levande är att skylta med mat, då kommer även djuren ut ur skogen till soptippen.
Alla levande varelser är uppbyggda av grundämnena kol, väte, syre, kväve och även fosfor och svavel.
Our natural environment is the result of a long term evolutionary process and mankind is a part of it. Nature contributes in every possibe way to the making of life, whether it be of a plant, an animal or a human being. The conditions that sorround each individual, day and night, are the tests and challenges of life. All kinds of life need air, water, minerals, light and warmth but without homeostasis all contributions of nature remain useless to life. Homeostasis is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition.
Humans are noted for their desire to understand and influence their environment, seeking to explain and manipulate natural phenomena through science, philosophy, mythology, fables, tales, and sagas. This natural curiosity has led to the development of advanced tools and skills, which are passed down culturally; humans are the only animal species known to build fires, cook their food, clothe themselves, and use numerous other technologies.
