medhrk. The greenhouse effect is caused by the burning of fossil fuels and deforestation-is true. The burning fossil fuels leads to emission of CO2 in the air which is green house gas. deforestation makes the number of CO2 consumer less in quantity so increase CO2 level.
Fossil fuels, even when burned perfectly (natural gas, or methane, burns the best) release carbon dioxide which is a greenhouse gas causing dangerous global warming. Most fossil fuels also release smoke (leading to smog), and they may also release sulfur oxides and nitrogen oxides which contribute to acid rain.
