What are four concerns about global environment

One of the most important areas of environmental concern, according to the EPA, is a concern for our water. Air pollution isn't an issue that most people consider to be of primary environmental concern since it doesn't seem to pose an immediate pressing threat for a lot of us. However, air pollution causes serious health problems and threatens the natural environment of the planet which means that this is actually one of the most important areas of environmental concern that we can start working to change today. Another area of grave concern that impacts many different parts of this planet is the issue of waste. Toxic waste, such as the placement of electronics into landfills on a wide scale basis, is a major issue but all areas of waste are of concern. All of these different types of pollution and waste end up contributing to what is probably the biggest area of concern that we have for the planet - the changing climate. Climate change is a major environmental concern because of the fact that even small changes can cause significant problems for large portions of the world.
