Slide1:

Tropical Savanna Ecological Problem

Slide2:

Since the Savannas are so dry there are many wildfires. These fires burn the little bit of vegetation that is in the savannas. Humans have made the soil worse by over farming it. If the biome is too dry, there won't be any water for the animals to drink, they will die of dehydration, and eventually become extinct. Grevy's Zebra, the African Elephant , the African wild dog, the Black Rhino, and the Cheetah are all endangered species in the African Savanna.   Animals

Slide3:

Human There are many threats which assail the grassland biome of Savanna, most of which are caused first and foremost by humans and their actions towards this place (most of which are explained in Effects and impact of human progress), although there are still several threats which are caused without any (or with little) human involvement. 

Slide4:

EXTINCT AND ENDANGERED ANIMALS OF THE AFRICAN SAVANNA.  ANIMALS HUNTED FOR PLACE IN THE FOOD CHAIN STATUS Elephant Tusks Herbivores Vulnerable C.D Leopard Skin Carnivores Vulnerable / Endangered White Lion Skin Carnivores Critically endangered Giraffe Skin Herbivores Lower risk C.D Lion Skin Carnivores Lower risk Tiger Skin Carnivores Extinct in Africa Tigers: Some people believe that tigers lived in Africa; others argue against that. These are just some of the extinct or endangered animals of the savanna. As you can see most of the animals hunted are carnivores and nearly all of them are hunted for their skins. The elephants however are hunted for their tusks, because of the money that is made.  The white lion is hardly heard of because it’s so rare otherwise the lions are at a lower risk. 

PROBLEMS AND POLLUTION IN THE SAVANNA :

PROBLEMS AND POLLUTION IN THE SAVANNA   Over the years humans have hunted many African animals to extinction, or close to it. Many of these animals are not mentioned in websites or books mainly because they haven’t been discovered yet. Pollution is one of the main threats to Africa’s savannas. The air can be polluted by smoke and exhaust fumes. If the air does get polluted animals will find it increasingly hard to breath and since they can’t move out of the country they will eventually die out. Carbon dioxide (CO2) increases the heat of the biome, if too much carbon dioxide gets into the air the animals that have adapted to the plains may have to adapt again to fit into an almost desert-like biome. Seasons may have something to do with the savannas’ fate.

Slide6:

What if the seasons change their routine? What will happen to the savanna if they do? Well, if the seasons change their routine (by coming earlier or later than expected e.g. summer comes two months earlier) animals that hibernate in the winter will expect the wet season to arrive in June and may die out if the season arrives any earlier or later as their food would have gone back into hibernation (or may have already died out). Water is one of the most needed things in the world.

Slide7:

Again most of the water that is in the savanna today contains many chemicals, as it has been through polluted areas with starving people and large factories. All animals have to have water. If the water is polluted the chemicals will pollute the animal’s body and then the animal will die out. The food chain has a lot to do with this. If you take out the dung beetle you will have a lot of dung around and the animals could die from diseases. Right now there are some of these things happening and there is a possibility that these horrible things could happen. The dams hold in the germs and so when the waters released it carries the germs down through the country and into the bodies of the animals. Now the animals are being hunted and the water is being polluted. However there are people who try to preserve this ecosystem and its animals. 

CONCLUSION :

CONCLUSION The conclusion is that this ecosystem is delicate and it needs to be kept in balance. Although some people try to conserve the environment and the animals in it, the main thing that’s happening here is global warming. This problem is not helped locally by some mining, but the main problem comes down to bad land use.
