You can help a lot of rescued animals by visiting this site daily and clicking. It's free. Will cost you only a few seconds of your time.
At the top of the page you will see tabs for other charities that work the same way, but for people. Click those, too. Less than a minute of your day. Don't give me excuses. There are none (as long as you have a working computer and internet connection).
Same sort of thing here. You can save land for free. Just click.
I have these on my "bookmarks toolbar" so I can visit them easily every day. I'm sure your browser has a similar feature.
