Final answer:
Global engineering proposals to reduce Earth's greenhouse effect include removing greenhouse gases, reducing sunlight, and addressing plastic pollution.
Step-by-step explanation:
Global engineering proposals to reduce Earth's greenhouse effect include:
- Removing human-caused greenhouse gases from the atmosphere and disposing of them somewhere else. This can be achieved by implementing sustainable practices, such as reducing carbon emissions, protecting forests, and promoting renewable energy sources.
- Reducing the amount of sunlight reaching Earth. This can be done through geoengineering techniques like installing reflective panels in space or cloud seeding to create more cloud cover.
- Taking all the plastic pieces floating in the ocean and blasting them off into outer space. While this idea may sound drastic, it is not a viable solution as it does not address the root causes of greenhouse gas emissions and climate change.
