Today, many countries are facing an approaching crisis in the management of solid waste as many waste disposal sites are nearing their capacity and the contents are continually degrading the environment. However, new and advanced solid waste management systems can help to reduce solid waste disposal, and subsequently minimize environmental and health impacts.

Most widely referred to as nuisances, open dump sites can be found on both private and public property; sides of the road, ditches, river/creek beds, secluded forest/woods, back yards, and empty lots.

Introduction: Thesis statement: Therefore, even though there may be some concerns in terms of safety and waste disposal, it could be an advisable option for countries to focus more on developing nuclear energy because it is environmental friendly and cost-effective. II. Body 1. Concerns A. Safety 1. Nuclear radiation on residents (e.g. Chernobyl & Fukushima disaster) → threat health and lives of residents 2. Nuclear radiation on workers→ cancer A. Waste disposal 1. Deep Geologic Disposal (difficult to build, 30-60 years) → few constructed storages for nuclear waste 2. Difficult to safely transport (e.g. Goiania) 2. Benefits C. Environmental friendly 1. Less carbon dioxide → mitigate greenhouse effect 2. No polluting gases → mitigate air pollution D. Cost-effective 1. Little nuclear fuel → much energy → effective 2. Lower unit price of nuclear power → economic III. Conclusion Benefits ( environmental friendly & cost-effective) ＞ concerns ( safety & waste disposal) → develop nuclear energy （1157 words） With the rapidly increasing population, human being’s demand for energy has become more urgent.

Nowadays, whether or not the trade-driven globalisation conflicts with preservation of the environment and natural resources environmental is a controversial topic (Heywood, 2014).

From an economic point of view, both world trade and environmental protection are important because they are the essential for promoting sustainable development, due to this reason it is possible to reconcile their continued levels. Hence, addressing the conflicting aspects and maximising the opportunities between them are necessary.

...Artwork about Environmental Education Essay: Importance of Environmental Education There are many challenges faced by our government and ourselves in protecting our environment. Such challenges are caused by lack of discipline, greediness etc. The challenges that we are facing today to protect our natural resources are illegal loggers, deforestation projects, irresponsible disposal of wastes, careless use of products from natural resources, and other over produced products from natural resources. Hopefully if we will be able to stop this challenges we could be able to help preserve our environment. For me as a youth of this community, the importance of environmental education is that you will be able to learn about the things that can happen in an environment. You will learn about the cause and effect of such things in the environment when such people do certain activities. Also through environmental education, we will be able to know the importance of our environment. This will show how humans manage their behaviour and interaction with our environment. As a normal citizen of our country I could help protecting our environment in my own simple ways like : proper segregation of garbages, recycling things, help in community services, using paper instead of plastics for containers, and lastly by conserving energy. With proper disposal of garbage we can minimize the volume of wastes in our community thus helps us prevent air and water pollution. If we recycle things we...

...Super Freakonomics: Short Essay questions Chapter 1: Describe the evidence that suggests that Chicago prostitutes engage in price discrimination. In addition, explain why it is possible for this particular instance of price discrimination to be successful. There is a couple of different things that directly show how Chicago prostitutes engage in price discrimination, the first is by skin color. The book directly says “Prostitutes do not charge all customers the same price. Black customers, for instance, pay on average about $9 less per trick than white customers, while Hispanic customers are in the middle” (p 35.) Another big one is giving police officers “freebies”. Some of the more high class prostitutes were able to discriminate even further by raising their rates on people they didn’t like, while still offering the previous rate to favorite customers, this is represented in the book by the statement “She grandfathered in her favorite clients at the old rate but told her less-favorite clients that an hour now cost $400” (p 54.) The last big one to mention is price discrimination for drug dealers, or price negotiations for drugs. Prostitutes are savvy businesswomen who know how to price discriminate very successfully to get what they want. Many factors contribute to why prostitutes are able to pull off such successful price discrimination. The book outlines the two major conditions that must be met to allow price discrimination to be possible in business, customers...
