The island is also home to around 170 palm species, three times as many as are found on mainland Africa; 165 of these are endemic. Many native plant species are used as effective herbal remedies for a variety of afflictions, including the Madagascar periwinkle, which has recently been established as the most effective treatment for leukemia and Hodgkin's disease. [16] The traveler's palm, endemic to the eastern rain forests,[21] is highly iconic of Madagascar and is featured in the national emblem as well as the Air Madagascar logo. [22] Like its flora, Madagascar's fauna is likewise diverse and exhibits a high rate of endemism. Lemurs have been characterized as "Madagascar's flagship mammal species" by Conservation International.
The IRL serves as both a spawning ground as well as a nursery for many species found in both lagoon and ocean settings. The IRL contains in excess of 4000 animal as well as plant species, including manatees, dolphins, coastal birds, sea turtles, mangroves, and many species of sea grass. Approximately 35% of the country’s population of manatees resides in or regularly migrates through the lagoon. The IRL’s bird populations are among the largest in North America (Dybas, 2002). The IRL is both a unique, and diverse, shallow-water estuary of national significance and makes up approximately 40% of Florida’s east coast.
Companies and poachers are largely destroying Rainforests. Rainforests are not only beneficial to humans but also to the numerous animal and plants species. They supply much of the oxygen humans need to survive. In addition, some of the trees and plant species within the forest provide essential components in producing medicine. In the 1970s, environmental ethics emerged.
Geography Midterm Study Guide Key Concepts& Definitions (Make sure to use Case Study and Examples to Backup Argument) Political versus Apolitical Ecology Political Ecology: The study of the relationships between political, economic and social factors with environmental issues and changes. Political ecology differs from apolitical ecological studies by politicizing environmental issues and phenomena. Apolitical Ecology: Four Main Theses of Political Ecology: • Degradation and Marginalization Thesis The thesis is basically this: because of state intervention and development of land in various different cases, systems of land and farming undergo radical changes that usually result in an exploitation of resources. Communities become marginalized as the same forces challenge the existing structures of governance and operation in each community. The two standout case studies in Robbins were deforestation in the Amazon and banana farming in the Caribbean.
Aldo Leopold’s “The Land Ethic” is an article addressing concerns on the liberties we have taken with the biotic community and our lack of obligation to the land. It is an attempt to awaken society to their role as conquerors of the land and a step in making us citizens of it instead. He begins by describing to us the actions of the Greek Hero Odysseus to slave girls and how our current ethics have evolved to protect individuals in our Community. Leopold states: the complexity of Co-Cooperative mechanisms has increased with population density. That is to say that the more members we have in our community (people) the more complex our ethics and tools become as a way to cope with the increase in population in a way that keeps the individuals happy For instance; the golden rule or Democracy’s integration of social organization to the individual.
Tropical rainforests are some of the most diverse places on earth. Tropical rainforests house more than fifty percent of the earth’s animal species (Michael). This biome is also the home to a wide variety of plant species, and many insects flourish in this type of environment. The tropical rainforest is the epitome of a utopia for equatorial species. The great diversity of the tropical rainforest provides great services to the earth’s human population.
An ecosystem can range from a mere backyard garden to a vast land under rainforest. Animal body is sometimes considered as an ecosystem since it can support life. The words "environment" and "ecology" have been increasingly in the news. Man is beginning to fear that his daily activities may be limiting the future use of resources. Pesticide use and drift can affect air quality; pesticides in the food chain can threaten wildlife populations; and soil may no longer be suitable for optimal crop production.
One possible approach is to regulate agricultural and industrial activity so that pollution and disruption to natural habitats is kept to a minimum. People argue that economic prosperity must be curtailed if it comes at the expense of the environment. However, businesses affected are unlikely to comply with such a strategy. It may even generate hostility to conservation efforts generally if the economic costs are perceived to be too high. An alternative approach would be to protect and expand nature reserves so that complete ecosystems can be kept intact.
Introduction: Soil inhabiting microbes play chief role in damaging juvenile plants under nursery. Pre-emergence or post-emergence nature of damage may leads to complete damage. However, many serious diseases are associated with soil-borne plant pathogens, which results in damping off, root rot, crown rot and wilts in various field and horticultural crops especially in nursery stage. Soil borne diseases are a common problem in nursery production which leads to sustainable economic loss by attacking the juvenile plants at early stage of life. Practical application of this knowledge will lead to healthier plants and improved plant growth with greater uniformity.
Traditionally, EJ originates from the sociological issues, such as the ethnic discrimination of local communities and specific ethnic groups2; however, from Latin America’s perspective3, EJ refers to economic issues, such as criticism against the “Capitalistic-dominated” development model. To some extent, the Latin America’s perspective refers the root of Environmental Injustice. In developing country, economic considerations will indirectly generate the environmental problem, when different groups only care about the economic merit, but ignore the consequence of environmental damage after exploitation. In this article, part I will explain that Economic Development is the root of environmental injustice in Developing Country. Part II is going to talk about the obstacles in pursuing environmental justice and finally, How to promote environmental justice will be illustrated in Part III.
