Reduce, reuse, recycle, repair: This kid recycles her toys. She knows her 4 Rs!Remember your four Rs!

The four Rs help cut down the amount of trash that ends up in landfills like thisIf you can't do any of those things, the waste you generate ends up in huge landfills. Much of what you find in these stinking dumps is plastic waste. This is a special problem so I have written a guide to the problem of plastic which I hope you'll look at. You'll be shocked by what you find out just as I was when I was writing it!
Recycling
Recycling doesn't save much energy directly, but it means that less new stuff is needed (so less energy is needed too), and less trash ends up in landfills.
If something you have breaks, consider repairing it. After all, if it's broken and you were going to throw it out anyway, you've nothing to lose and everything to gain. Tip: Strong epoxy glues are good for most repairs. But some repairs need to be done by professionals: I'm thinking of computers, TVs and electrical stuff where high voltages could kill you if you don't know what you're doing.
