The correct answer is D. Make it warmer
Explanation:
One of the most important factors that regulate temperature on Earth is the action of greenhouse gases such as carbon dioxide because these gases trap and reflect back part of the radiation from the sun, which creates a warm environment that is ideal for life. This implies, an increase of carbon dioxide due to the burning of fossil fuels, industries, etc. will lead to more radiation staying on Earth, and therefore there would be an increase in Earths' temperatures. Moreover, this situation might affect negatively life as many species cannot prosper in higher temperatures. According to this, burning fossil fuels will make Earth warmer.
