A closed ecological system is an ecosystem that sustains life by fully reusing all of the resources at hand, in particular through cycles wherein exhaled carbon dioxide, fuel, and other waste materials are transformed chemically or through photosynthesis into oxygen, water, and food.
Why ecosystem is considered an open system?An open system allows for the flow of both matter and energy with its surroundings. An open system can be found in any environment. Sunlight, for instance, can provide energy to the system and heat can be released.
It continues to be the biggest artificial closed ecosystem ever made. Biosphere 2, which was built between 1987 and 1991, was initially intended to show that closed biological systems could sustain and preserve human life in space in place of the biosphere on Earth.

Why might policymakers feel that the fight to stop pollution is Sisyphean
Answer:
Because if we stopped polluting, that would mean we have to cut back on non-renewable resources, which pollute the environment. But if we did that, energy would be harder to get, maintain and use because it will depend on the sun and wind. So if we outlawed any pollutants, many people would have too little energy and might starve or even be able to use the computer once every day. From the same perspective, if we keep polluting with non-renewable resources, then more people will die of deadly gases and more environments will be harmed. Therefore, the fight to stop pollution is Sisyphean.
