The scale of the challenge across Africa is enormous.After all, it's a huge continent.The United Kingdom, China,the United States of America, India,Japan and most of the rest of Europewould all fit within its borders.Africa still retains 45% of the Earth's uncultivated land.It's still the greatest wilderness on Earthand that is why it's important.Human beings have lived alongside wildlife herelonger than anywhere else.But now in the 21st century,animal numbers are at a critical level.Like it or not, this generation is responsiblefor handing on the world's wildlife to the next.That means taking care of the animals and lands where they live,so there is still space for us all to coexist.
