Please help ! Much needed help

so with this I would chose pollution and for it the cause is pollutants and green house gases and then solution would be to find less pollutant versions of producing stuff and using renewable energy and you can research more about solution and cause and then for bill it can be a percentage to cut pollutants in the atmosphere to a legal limit or companies get fined or reprimanded
