In many countries practical solutions to protectwildlife do exist, but a recovery plan cannot beuseful without jointly enforcing legislation world-wide. Trade in endangered plants and animalsis now internationally prohibited, as is commercial exploitation, and so what? Penalties forviolations used to be too minimal to stop such destructive human activities as illegal huntingand deforestation and pollution, even though nobody should like to see the situationbecoming bad to worse.
To begin with, the habitat of flora and fauna has been losing ground, although it is not knownexactly how many species of animals and plants have been killed off or wiped out on earth sincethe Industrial Revolution. And how many more are disappearing at an alarming rate. Untilrecently few thought that human actions could affect the world's ecosystem on a globalscale. It is as if anything that humans touch is doomed. These days many are more sure thatsuch actions are occurring, and that this problem is so big that no government can tacklealone. Accordingly, the biodiversity—living things and relationships among them, demandinternational actions.
Gradually, the public is beginning to worry that the worse is yet to come. Some fear that if littleor nothing is done in time to prevent the disaster from happening , humankind as speciesmight be doomed as well. Such is at least the view held by quite a few scientists andenvironmentalists who call for severe sanctions, or else. Others, however, believe that the caseis not hopeless. The good news is that there is an increasing awareness of the great dangerhuman beings are in. An urgent global commitment has actually been reached to join forces tomaintain ecosystem, saving Nature for Nature's sake, despite the fact that in certain crucialfields apparently not enough has been done. As it is, protecting the natural mechanisms andpreventing pollution are hard tasks to deal with, nevertheless human beings ought to trustthemselves in meeting the challenges, by reason or by force.
Excessive logging, illegal hunting and fishing, and out-of-control pollution continue in manycorners of the planet on penalties of heavy fines and criminal charges, but concernedgovernments across the world are no longer turning a blind eye. It is a truth universallyacknowledged that, unless effective measures are taken altogether at once, mankind's road todoom is sure, although very slow. Fortunately human beings now know that harming the earthis easy like pulling bricks from a giant wall, and that they may keep doing it until the wallsuddenly collapses.
