We should switch over to energy sources like the sun and the wind. Why ❓ Hint : think about the renewable and non - renewable sources of energy.

Answer:
Explanation:I think the emphasis on just renewable energy is not enough. For one thing, in practice, that takes a long time. More importantly, it may eventually not even be enough to solve the problem! A global and concerted effort at reforestation is needed. It makes the planet look better, and creates a more robust, self regulating system, where we would not rely only on our collective ability to hold our breaths (so to speak).
The numbers are not hard to find. Humans generate approximately 3% of the total daily output of CO2. If we had as much forest as there was before the industrial era, there would be no need to worry over our small extra contribution. The problem is that we are simultaneously (still) deforesting and dumping more CO2 into the ecosystem.
I did some back of the envelope estimates not too long ago. If we could restore at least half of the forest we have destroyed, that would be just enough to process the CO2 we are generating today. Combined with renewable energy, I think this is the more credible long term solution. Because if we continue to deforest, nothing will stop CO2 concentrations from increasing.
Forest restoration is taking place in the US and other parts. Unfortunately, although the net is positive forest growth in the US and some other countries, the net is still negative, globally. That has to change. Sooner or later, you know, you do have to take another breath. We can't allow just that act to cause a calamity.
