lithosphere

Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air).

Humans can have major impacts on all the spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere.

We live because there are people who love us, and people we love back. We live because we want to find out things, and learn, and become able to do things that we would like to do. We live because others want us to, and we want them to live along with us. We live because we have hope, and want to see what happens next.

Human beings have certain basic needs. We must have food, water, air, and shelter to survive. If any one of these basic needs is not met, then humans cannot survive.

In order to survive, animals need air, water, food, and shelter (protection from predators and the environment); plants need air, water, nutrients, and light. Every organism has its own way of making sure its basic needs are met.

An article in Archiv Fur Kriminologie states the body can survive for 8 to 21 days without food and water and up to two months if there’s access to an adequate water intake. Modern-day hunger strikes have provided insight into starvation.

In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal’s home (habitat) must provide these basic needs (air, water and food) along with shelter from bad weather and predators.

Most living things need food, water, light, temperatures within certain limits, and air. Living things have a variety of characteristics that are displayed to different degrees: they respire, move, respond to stimuli, reproduce and grow, and are dependent on their environment.

These are humans’ six basic needs in the 21st century

• Food. Food is the basic source of energy and one of the most immediate requirements for day to day survival.
• Drinking Water and Sanitation.
• Healthcare.
• Shelter.
• Education.
• Access to Information.
