Birds, Human Population Growth, and Climate Change


Slowing Population Growth Would Help Climate Crisis, Too

Climate change and human overpopulation are tightly linked. The Intergovernmental Panel on Climate Change says the rapid growth of the world's population is one of two primary factors driving global warming.

Now a new study by Dr. Philip Cafaro makes the case that slowing human population growth through voluntary programs should be on the list of solutions for tackling climate change. The discussion comes at an opportune moment, with the world population topping 7 billion and the climate crisis worsening. The Center for Biological Diversity has been working for years to highlight the effects overpopulation is having on plants and animals around the world; we think slowing human population growth by empowering women and improving access to family planning will have benefits for everyone and be a crucial part of easing the global climate crisis.

Study: Climate Change Means Bleak Future for Birds

Imagine a world without birds -- or at least without many of the birds that brighten our lives today. According to an analysis of more than 200 individual studies of climate change's effects on birds, 600 to 900 land bird species (out of 8,500 worldwide) could disappear by 2100 -- and that's if the Intergovernmental Panel on Climate Change's middle-range projection of a 6.3-degree temperature rise occurs. The extinction toll rises by another 100 to 500 birds by each degree of warming above that projection.

It's yet another wake-up call on what we stand to lose if we let the climate crisis go unchecked.

Read more on the study in The New York Times and check out the Center for Biological Diversity's Web page about the alarming climate changes already underway. It features an amazing video showing 131 years of warming in 26 seconds -- and making it even clearer that birds don't have much time.
