Letter | Global warming threatens polar bears - and us

I read with interest your science article on the starvation of polar bears due to the disappearing Arctic sea ice. My only criticism is that the article said nothing about human starvation.

We must ask ourselves a question. If polar bears starve due to losing access to seals, their main food source, because the Arctic Ocean is warming up, what are the long-term prospects of feeding 8 billion humans in a warming world?

Many of us reside in regions where increasing temperatures threaten the crops we depend on. Maybe we should get serious about reducing the carbon emissions that are driving the warming process, including applying economic pressure to force China and India to reduce their emissions. Those carbon emissions in Asia are climbing steeply with those in the U.S. have declined slightly.

The bipartisan PROVE IT Act in the Senate is a first step towards a carbon tariff to punish nations that abuse our trade system with carbon intensive products. We should all ask Sens. Tim Kaine and Mark Warner to join the sponsors.
