Which two actions can people most reasonably take to decrease the amount of air pollution?

create filters to clean all the air in the atmosphere
research ways to decrease pollution in car gas waste
build ships that remove plastic from the ocean
filter waste gases from factories
shut down all factories

Answer 1

To reasonably decrease the amount of air pollution, the two actions people can most effectively take are:

1. **Research ways to decrease pollution in car gas waste** - This action focuses on improving the emissions from vehicles, which are a significant source of air pollution. By developing cleaner technologies and alternative fuels, the overall pollution from cars can be reduced.

2. **Filter waste gases from factories** - Implementing filtration systems in factories can directly reduce the amount of harmful pollutants released into the air, thus improving air quality.

The other options, while beneficial in different contexts, are less practical for directly addressing air pollution in urban environments.
