1. Changes in ecosystems have a more direct and brutal influence on human well-being among poor populations mostly in developing countries than among wealthy populations.
It has become a matter of urgency to balance the issues of development and environment so that the current generation hands over the earth to their future generation without any further damage to the environment. The development process of any kind should always be sustainable.
Sustainable development is a recent concept that has become important for a wide range of people and industries. Sustainable Development involves maintaining the current rate of development leaving suitable resources behind for later generations to continue to develop.
Sustainable development includes both the issues of environment and society and tries to strike the balance between the human being and the environment. Sustainable development means the integration of social, economic and environmental factors into planning, implementation and decision-making so as to ensure that development serves present and future generations;
2. In one page discuss the earth as an open and closed system
The Oxford dictionary defines a system as an “interrelated interacting artifacts that can work as a coherent entity.” A system consists of three basic elements:
a functioning set of components,
a flow of energy which powers them, and
a process for the internal regulation of their functioning called feedback
Ecosystem - is a system that models relationships and interactions between the various biotic and abiotic components making up a community or organisms and their surrounding physical environment.
An example of a system is a car with its many parts which functions as unit. Processes that ...

Toxicology is the investigation of the unfavourable impacts of chemicals on living creatures. Forensic toxicology takes it above and beyond, including various related controls to aid in the location and elucidation of pills and harms poisons and drugs in medico legitimate passing examinations, human execution issues; e.g.,
Katrina Fox’s article, “The Human Cost of Animal Experiments” talks about how some of these tests are not always correct or accurate. About two million Americans become ill from drugs and these drugs were deemed good to release to the public. Out of those two million people, one hundred thousand people die from these drugs being released. The U.S. Food and Drug Administration approved two-hundred nine new drugs from 1976 to 1985 and those drugs caused severe side-effects. Some of these side effects were heart attacks, kidney failure, liver failure, and stroke (Fox 1). Drugs do fail and some of the tests can be harmful or even fatal to humans. This is what a textbook on animal experimentation states, “Uncritical reliance on the results of animal tests can be dangerously misleading and has cost the health and lives of tens of thousands of humans” (Fox 2). This states even medical professionals do not even believe in animal testing and it has cost humans a lot of lives. In the next section, questionable accuracy of toxicity tests is discussed. The inaccuracy of toxicity tests is the main reason why the drugs cause adverse reactions. For example, the LD50 Draize test is when animals are fed harmful chemicals and half of them are killed (Fox 3). This test can be very unreliable because the different variables such as the weight, age, and gender of the animals. This test can make the results inaccurate for the
Animal testing is also dangerous. Animals and humans can react differently or indifferently to chemicals, because humans are different from animals in anatomy, phycology, and metabolism. One study conducted by the pharmace...
Hello, in this speech I want to talk about the term "sustainable development" and what it means for me and for the world. For me, sustainable development is a new way for the world to improve its present and have more options for a good future. This method, which most countries have begun to use to fight against the ecological problems on the planet, is of great importance to maintain many things that exist on the planet today, like many animals or plants. In addition, this plan will improve people's living standards, in addition to helping with social problems and the daily lives of many people, such as education and work, also help poor people with better living conditions. Now I want to explain, from my point of view and based on the information
The word sustainable Development beginning first with sustainable means conserving an ecological balance by avoiding depletion of natural resources and the word development a progress of quality and quantity from lower level to more advance, mature and complex of stage. If we compared these two word together sustainable development makes a complex global meaning which is ambiguity to define with easy terminology, meaning our fundamental commitment of the future balancing and avoiding and trying to eliminate the negative impact using the word sustain to compromise and meet the future generations needs and expectation depend on nature. The ambiguity definition of Sustainable Development it operationally and according to Roger approved definition by UN General Assembly 1983”Meeting the needs of the present without compromising the ability of future generations to meet their own needs’ (Brundtland Commission, 1987; cited Rogers et al, 2008: p. 48)”
The ecosystem services provide stream of goods and services which are very much important in the maintaining the economic prosperity and other aspects of human welfare. Goods typically refers the natural harvest such
The three pillars of sustainable development are environment, economy, and social justice. If our environment isn’t happy, then the economy isn’t happy because maybe plants aren’t growing as well as usual because the environment isn’t happy. Then, if the economy isn’t good that means more people get worried, stressed, and unhappy. This can lead to problems with social justice. In order to have a sustainable development, these three pillars need to be balanced and working together. A lot of things sort of rely on the environment and how we are taking care of it in the long

Sustainability simply defined to me as balancing act between the development of sustainability is necessary for both planet Earth and humans to survive. This is reinforced in the World Commission on Environment and Development report (1987) that sustainable development must meet the needs of the present without compromising the well-being of future generations”. The Earth Charter Organization widened the idea of sustainability to respect for a culture of peace, universal human rights, nature, and economic justice (What is sustainability?, n.d.).
Economic growth and social development are complementary and close relationship constraints. However, with economic growth, it is clear that there are many environmental concerns in today’s society. Air, water, and land pollution have been worsening; the environment of wild animals and plants have been seriously damaged, many species are threatened with extinction, deforestation and over-exploitation of mineral resources give human survival and development a real and more serious potential threat.
Then what is an ecosystem? An ecosystem is a concept constructed by human society that aids us in perceiving an amazingly complex structure of interactions. This construction is rooted fundamentally in our language and the discourse that surrounds environmental issues. As such, the concept of discourse and the practice of discourse analysis are vital to understanding what an ecosystem might be.
Sustainability or sustainable living is development that satisfies the demands of the present without compromising the competence of future generations to satisfy their own needs.
