Are our zoos cruel to wild animals Humankind has a long history of relationship with animals. Many people believe that animals play a very important role in human life. They are living-organisms‚ we see around us every day and like we humans‚ they respire‚ they eat‚ they move and try to survive in this world. These creatures have always attracted us by their beauty‚ their way of living‚ their abilities or skills (running‚ jumping‚ attacking etc). People have always wanted to see these beautiful

Adaptations of Savanna vegetation. Savanna vegetation must adapt to survive. Many problems must be overcome‚ such as lack of water‚ very seasonal rainfall‚ poor soil quality‚ grazing animals‚ very high temperatures and fire. 1. Define the following terms: Xerophytic = A plant adapted to living in a dry arid habitat; a desert plant Pyrophytic = plants adapted to tolerate fire Deciduous = Loss of leaves seasonally Perennial = lives more than 2 years Dormant = A condition of significantly

Many species today are impacted by threats from changing environments. These threats can pose a great amount of harm to a specific species‚ which in turn‚ can ultimately cause it to be endangered. A species is considered endangered when a threat is relatively high and a population is rapidly declining in size. One of the most effective ways to identify an endangered species is through acknowledging habitat loss‚ introduced species‚ pollution‚ and overconsumption. This paper will investigate two endangered

1. How does a culture’s physical environment shape the type of subsistence pattern they practice? How does subsistence impact a culture’s degree of social stratification? How is the degree of social stratification mirrored in religious systems? The amount of sunlight and rainfall and the types of soil‚ forests‚ and mineral deposits all have an effect on the type of subsistence pattern a particular society develops. For example‚ In the U.S society people have different choices to obtain their

Cascading Trophic Effects in Response to Apex Predator Removal Introduction The seemingly simple interaction between predator and prey can create effects that disseminate throughout an entire ecosystem. These interactions‚ or lack thereof‚ specifically result in trophic cascades. Cascading trophic effects typically occur from a change in the population density of apex predators. Due to the ever increasing impact of humans on nature‚ this field of ecological study is gaining more popularity as ecologists

All economic activities affect the environment in some way whether it is done intentionally or unintentionally. These could be positive or negative effects. Most of the time‚ they are negative. Most activities usually end up harming ecosystems or just polluting the environment. Economic activities can range from mining all the way to farming. This essay will discuss different types of economic activities and how they effect the environment. The first effect on the environment is the over harvesting

Ans-Environmental Damages of Mining Open pit mining Open pit mining‚ where material is excavated from an open pit‚ is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations‚ which increases the amount of ore needed to be mined.
