problem solution Day 5

A problem we have is heat from global warming. some of my possible solutions are:
1. burn more fossil fuels because it creates a bunch of greenhouse gasses like the volcanoes in 1991 that cooled the earths tempratures about 1 degree centigrade.
2. Plant more tree's and increase farming productivity to absorb some CO2
3. Kill more herbavor animals that eat the plants such as deer, ducks and geese.
4.I read this in a book, even if we increase in our emissions by 100% each year, by 100 years the earths tempature wil only increase about 1 degree celsius.
