The cells present in the tail of the tadpole undergo a programme cell death. This is made possible when the organelles called lysosomes present in the cells break open to cause the breakdown and digestion of all the components of the cells. The lysosomes are break open only when the cells receive a signal from their neighbouring cells to undergo apoptosis, a process where the cell kills itself.
The world has become very dependent on carbon-rich fossil fuels over time because of its high calorific value. This means that it produces a big amount of energy when it undergoes combustion. However, the by-product of combustion of carbon is carbon dioxide. It is a known greenhouse gas and pollutant. This is the risk the scientists fear that might affect the environment in the long run.
So, the answer is: <span>Scientists are not sure if the atmosphere can handle all of the excess carbon.</span>
