1. Introduction Scientific evidence of the world’s changing climate is unequivocal. The expected impacts of the changing climate are likely to adversely affect the well being of all countries and particularly the poorest countries‚ some of which are in Africa. The changing climate has been manifested in the form of: increased severity and frequency of droughts; floods and storms; water stress‚ coastal erosion‚ and higher incidence of vector borne diseases among others. The resulting declines in

Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius

Soil‚ which is one of the most important natural resources‚ is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved.

Over the decades‚ Invasive species have shown a significant negative impact upon the fabric of the ecosystem. Whether they are endangered or not‚ in-habitat species are making their presence known throughout the ecosystem‚ and such‚ throughout the United States. In fact‚ Invasive species have posed as a problem within society as around the early colonies of the 1800’s. The uncommon native-species are able to enter through different routes. Some are transported intentionally and others are able

Misconceptions of the Endangered Sharks “Strong jaws‚ teeth-like scales covering the body‚ gills‚ dorsal fins‚ pectoral fins‚ and a powerful tail‚ along with fantastic camouflage…”(Kraus 91)‚ sharks have been able to remain the top predator of the ocean waters for the past 400 millions years. They belong in the family known as the Chondrichthyes which distinguishes them from other of aquatic life in which they have evolved to have special skeletons made up of cartilage and connective tissues. These

Australia There are three major biomes in Australia: Tropical Savanna Desert Human Interactions Climate change impacts are expected to have significant social‚ economic and environmental consequences worldwide. Ongoing population growth and development in highly urbanized coastal areas will make worse the predicted impacts on the coasts. Climate The southern part of the state has a Mediterranean climate. South Australia ’s main temperature range is 29 °C (84 °F) in January and 15 °C

There are two types of rainforest biomes: tropical and temperate. Tropical rainforests are found near the equator and are moist and hot all year round. The climate in this biome is very humid‚ maintaining a high humidity of 77% to 88% all year round‚ due to the frequent rainfall. The rainfall is all year round and receive annual precipitation amounts from 60 to 160 inches. There is little to no seasonal changes in weather. The average temperature in tropical rainforests range from 70 to 85°F (21
