There are realistic things that you can do about climate change. You do not need to try to hide from it.
Climate change can be overwhelming because it is such a big problem. It is a vast relief to find things that give one hope about fixing the problem of climate change. We do not need to give in to despair over the size of the problem compared to our abilities.
I treasure any glimmer of light in our polluted darkness. One of these is a free online class. The awesome respectability of the class and its teachers is in itself a little overwhelming to me.
The class is given at Harvard University, one of the finest colleges in the world. They have other classes available on many other subjects, of course. Some of the other classes are interesting, but none has the importance of this one. It is, "Human Health and Global Environmental Change". It starts today. It is not too late to be included in this ray of light.

One of the professors of the class is an MD, a pediatrician at a famous hospital. The other professor has been studying the "quality" of our air for many years.
A book by one of the professors of the course, "Sustaining Life, How Human Health Depends on Biodiversity", is optional reading for students taking the course. The book is offered on Amazon, in both a hard copy and a digital, Kindle version. You can read these without even taking the course.
There are plenty of links to strong, useful information. There are lots of graphs and charts to make this information easier to understand and be able to explain to others.
The lectures are broken down into short video segments. You can use the materials at your own speed with a few exceptions. The course is broken down into sections and access is restricted to the current and past sections covered, to keep the eager beavers with the rest of the class.
There is a lot of information to be covered in the course. I am definitely glad that I refrained from taking other courses simultaneously. This is all information that I want to understand very well, and it is clear that this will require a lot of time.
I hope that some of my readers will join this class, now or later on, as it is repeated. The Earth and the people and the rest of the life on the Earth, need your attention, interest and actions.
We can not continue to exist in the face of indifference to climate change, and we need everyone who is willing, to get busy learning and acting to stop climate change.
