Excess nitrogen in the environment is a big problem. The most visible aspect of the problem is the spread of toxic algae blooms in oceans, lakes and other bodies of water. But there are other effects as well such as unwanted alterations to ecosystems.
Poor air quality is a major problem worldwide. 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, trailing only high blood pressure, dietary risks, and smoking.
Waste due to excess packaging of the products we buy is a real problem. It is one that most of us are conscious of and more and more businesses are making efforts toward eco-friendly packaging. There is increased use of cardboard, which is recyclable. Most of us try to reduce our waste through recycling. But as we buy more things online and have a growing variety of things delivered to our homes, it is a struggle to receive the things we order in good condition and not end up with piles of packaging materials.
