The Sahara desert has many harsh conditions such as these thunderstorms and rain also make it very difficult to survive there. In the Sahara, the rain usually never falls however when the rain falls somethings it can come so hard and wash away cars and homes. There are many factors that make living in the Sahara and the Sahel challenging, however, there are some conditions such as animals that make living in the Sahara desert possible. Based on the text, “Tuaregs depend on their animals for eggs milk cheese”(pg 303). The food provided from animals is necessary for life in the Sahara because the is very little water so the most of the
Farmers have to pay for technology that helps them keep up the land, and they usually have to pay people to help them because not all farmers can keep up their land by themselves. Also, restrictions from fossil fuels is another major issues for farmers. Fossil fuels help create fertilizers. Without fertilizers, crops would be vulnerable to pesticides and other things that would damage the plants. Today, people waste plenty of food; we over order or eat, and then throw away what we don 't want.
The livestock also made the soil more compact causing the soil to carry less water, making the land a less inhabitable environment for plants. This resulted in the Native Americans losing their crops. They also eventually had to start raising livestock and doing other European agricultural practices because, “Hunting too became difficult. Adjacent colonial settlements eventually tried to restrict Indian hunting on English land, and such key food sources as deer became hard to obtain.” (Cronon 103). When the Europeans noticed the Native Americans starting to lack the resources that they relied on, they took advantage of it.
The bad aspects, of course, are the damage to the rest of our food supply, the possible effects on health, the environmental damage that may cause problems and ultimately increase the price of food down the road (for example, climate change restricting areas where crops will be grown; or spreading dead zones making fish and shellfish less available). The other crops, the fruits and vegetables, are still being grown, but in more limited space and in more limited areas, making them in their turn potentially more vulnerable to difficulties with weather and climate change, and even things like mold or insect threats. There will also be a tendency for their farmers to seek more pesticides and fertilizers and modifications of the plants, be they by hybridizing or genetically modifying, in order to grow more in a more limited space, contributing more of the same sorts of environmental damage. Also, of course, these foods have become relatively more expensive. Choosing the cheaper corn-centered foods also causes consumers to miss out on some excellent nutrition and some great foods that can get overlooked when purchasing processed foods.
They effect the animals, plants and even some natural resources. Modern day golf courses try to limit the deforestation and animal conservation and also try to recycle the natural resources, but they still have a big impact on the eco systems ranging from birds and squirrels to the trees and grass. There are a variety of different t animals that use the forests and land that has now been destroyed as a home. When humans come and destroy these areas, the animals either have to move or
The Case Study of the Declining Biodivesity between Coyote Species and Rodent Species. What is Biodiversity? Biodiversity can be referred to as a variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it (What is Biodiversity? n.d.). Biodiversity includes all living things such as rare, threatened, or endangered species, the microbes, fungi and invertebrates.
II. Restate Thesis: Botswana 's ecosystem is very unique and diverse. They have many different types of animals, plant life, and climate. Topic Sentence for first main point. There are many different types of animals in Botswana.
The enviropig has a big influence on agriculture. Thus, enviropigs should be evaluated upon their direct effect on human nutrition and health, animal welfare related to the transgene itself, and the environment. However, the breeders of the enviropig themselves argue that its market is the developing world.  Enviropigs are not able to survive on their own in the wild as they fully depend on humans. Enviropigs are not yet approved by the food and drug administrative of health Canada due to the discoveries made aware to them.
Invasive species This refers to the animal and plant species as well as pathogens, which are not native inhabitance of a given land. The introduction of these animals to a new land is not recommended because of the harm they cause to the existing living organisms in that place (USDA). The invasive species create a significant change in an ecosystem in terms of constituents and the need for food and production. Initially, we have an ecosystem that has been balanced in terms of food chain and food web as well as the population growth. The introduction of the invasive species will create a new demand in terms of food, shelter and reproduction.
Due to the fact that there is also a lot of desertification (especially in Botswana) in many of the southern African countries, it not only makes it difficult to farm produce there, but over such long distances, delivery to the stores become more expensive as well as more difficult. Pick ‘n pay also need to keep in mind the suitability of their product due to the physical influence on them, for example, it is known that in Southern African countries, there is mainly the wet season and the dry season and that products need to be sold accordingly. Strategies: in order for Pick ‘n Pay to get around these problems, they need to take out
