Recycle, Recycle, Recycle! Most of my projects are done with things you'd find around your home and done with basic equipment, sometimes with just a pair of Pliers. There are also projects for more advanced viewers, involving a bit of welding and wood work.
Recycling is also crucial because of how waste can impact animals (and consequently, humans because of food chain). Waste can cause loss of natural habitats and contributes to negative impacts like climate change and global warming, which can also destroy animals’ natural habitats. When animals — and other biological organisms — lose their habitats, they can die off or starve.
Please use your own common sense in doing projects. If something looks unsafe to you, don't do it.
