increase int he use of fossil fuels

decrease in carbon dioxide emissions

decrease in the rate of deforestation

What leads to an increase in average global temperatures?

increase int he use of fossil fuels

All renewable energy sources are available 24 hrs/day.

What evidence could be used in an argument against planting the same crop in the same field year after year?

the same nutrients are taken from the soil resulting in nutrient depletion

pollution of the soil because the plants take the nutrients

the plants take the ethanol out of the soil depleting the health of the plant

farmers plant the same crops all the time and there is no harm to farming

How could pollution that i created in one state affect water and organisms in another bordering state?

Pollution can flow down the river to the ocean where it will impact other ecosystems

The bordering state is the point source
