Many of us like to have houseplants. They add a bit of nature to our homes and they look nice. It turns out that they have health advantages as well.

Our Air Is Killing Us
Poor air quality is a serious problem. Exposure to air pollution is linked to the premature deaths of an estimated 6.5 million people every year. This makes air pollution the fourth largest threat to human health. Only high blood pressure, dietary risks, and smoking are a bigger danger.
CO2 Air Capture
The level of carbon dioxide in the atmosphere has reached 400 parts per million and is still rising. Climate scientists say that 450 parts per million would be dangerously high. Many experts say that we really need to get back to 350 parts per million. We are trying to prevent global temperatures from rising more than 1.5 degrees Celsius.
Pulling Water From Air
As droughts have become more commonplace, researchers are looking at natural systems for effective ways to capture water from the air. A team from Harvard University has drawn inspiration from three different organisms to develop a better way to promote the condensation and transportation of water droplets.
Dangerous Air
Much of the public discourse about pollution is focused on the long-term consequences of greenhouse gases in the atmosphere. There are still some who doubt that such consequences are really in the offing or that our actions are responsible in any case.
Turning Air Into Fuel
There is a global effort underway to combat climate change. The carbon dioxide in the atmosphere is the primary culprit. As a result, there are two things to do about it: reduce the amount of CO2 we are dumping into the atmosphere and try to remove some of what is already there.
