Many dream of travelling in a spaceship. A few have experienced it. Projects are underway that would make public space travel a reality if you have lots of money.
A spaceship is a closed vehicle that travels through space. It must have systems to provide air, food and water, waste management and temperature control so the crew can survive.
Each person on the space ship must follow all the rules to ensure the systems continue to work for everyone. If one person eats too much food or puts waste in the wrong place the results could be disastrous for everyone.
In reality, we all are traveling on a space ship. The earth is a closed vehicle traveling around the sun. Aside from the energy from the sun, the Earth is the only source of what we need to survive.
It has complex systems that provide us with the food, water, air and climate we need to live.
Everything we do has an impact on the earth. We take the materials for everything we have from the earth. We need to be careful so our actions do not destroy these life support systems.
Laws to protect the environment have been made which has reduced or prevented damage. However, as scientists learn more it is clear these life support systems are being strained by human activity.
Everyone needs to form habits that reduce our harm to the environment.
Recycling uses less energy and resources than making things from scratch.
We need to make do with what we have and reuse what we can.
Reducing or using less is the most important thing to do to protect the life support systems on our spaceship.
