Overgrazing is the process by which domestic animals (such as sheep or cattle) degrade the land by eating more plant material than the land can sustain. That is to say the plants (such as grass) in a given area cannot regrow at the rate they are being eaten by the animals. This leads to problems with erosion, which can cause further problems for sustained plant growth if the topsoil washes away.
Current modern technologies could be wisely used to prevent ecological disasters, endangering of animal species, and to entire development of ecosystem, and all we have to do is to turn technologies in these directions. Humanity must become now more than ever before dedicated to preservation of their natural habitats. And we have only one natural habitat and this is our planet Earth. Earth has lately become surrounded with so many different ecological problems, of which some (like global warming) threaten with future catastrophic consequences.
Ecological problems also require appropriate legislative support that should ban modern technologies that have negative impact on environment, and only allow those technologies that do not have, or have only minimum of negative impact on the environment. Passive observation is not sufficient, especially now when we have become witnesses of so many ecological disasters.
It is really time for one global action, and who knows maybe this is our only chance to save Earth. So what are we waiting for?

When I make paper letters, I trace them using a stencil of the size I need and then cut them out with scissors. I usually use construction paper and often make the letters different colors. To make them last almost forever, I laminate them. If I have free access to a laminating machine, I use it, but clear contact paper does a good job, too. It just makes a softer finish than laminating material. An extra tip on the laminating part: cover one side of your letter/paper with clear tape, then cover the other side with clear tape too. Trim the tape down to match each other perfectly after its put on if you want. It makes a great seal, good for laminating, or mailbox signs- no water ever gets is!
