The Philadelphia Zoo: the story of endangered species

Through the use of amazing LEGO brick sculptures, set designs created to tell each story and informative interactions with Zoo staff, Creatures of Habitat highlights the Philadelphia Zoo’s global role in protecting wildlife. Kenney, one of only six LEGO certified professional artisans in the world, crafted more than 30 life-size animal sculptures from hundreds of thousands of tiny LEGO bricks. Fragile in the wild, some on the brink of extinction, the species represented in these sculptures range from Borneo to Brazil and the Arctic Circle to Africa, and in size from a 500-pound polar bear to the delicate golden lion tamarin, which usually weighs less than one pound. A truly international collaboration, the intricate Creatures of Habitat set designs are the work of the Zoo’s creative team with illustrations provide by Jo Tronc, the famed New Zealand illustrator."

Be aware of what goes into making a pair of blue jeans
Honestly speaking Denim jeans are fashionable and worn by almost everybody, but be aware of the environmental impacts on
China’s Pearl River Delta.
Known as the blue jean capital of the world, China’s manufacturing industry is one of the largest polluters on the planet.
Watch the following video:
CNN's Emily Chang comes across piles of trash, many of which contain scraps of blue denim.
The Pearl River Delta is at the center of much of China's manufacturing industry. Its banks are lined with thousands of factories that produce huge amounts of waste, much of which gets funneled into the delta, Chang reported from Guangzhou.

Germany's First Offshore Wind Farm
Germany's energy supply is on the verge of an important turning point. Over the coming months and years, German utility giants plan to build massive offshore wind farms that are expected to produce huge amounts of green energy.


In 2007, Germany made a commitment to the European Union to substantially reduce its CO2 emissions. Chancellor Angela Merkel promised that her country would play a "pioneering role" in European and global climate protection. The goals were no less ambitious.
By 2020, Germany intends to reduce its emissions of the greenhouse gas carbon dioxide by 30 percent over the base year of 1990. In its bid to reach this goal, the German government is taking an unorthodox approach within the EU. While its European neighbors plan to reduce their CO2 emissions through a mixture of energy conservation programs, the expansion of renewable energy and nuclear power, which has low CO2 emissions, Germany is standing by its plans to phase out nuclear power, which were announced by the administration of former Chancellor Gerhard Schröder.

Wind energy reduces electricity prices, says independent study
Wind power reduces electricity prices and CO2 emissions, a study published today by the European Wind Energy Association (EWEA) reveals.
The review ‘Wind Energy and Electricity Prices’, a comprehensive assessment of studies of the impact of wind energy on electricity prices, was carried out by the independent consultancy Pöyry AS on behalf of EWEA. It brings together, for the first time, the findings of case studies in Germany, Denmark and Belgium.
The report finds that in the studies reviewed by Pöyry, electricity prices were reduced by between 3 and 23 €/MWh depending on the amount of wind power. It concludes that the studies “essentially draw similar conclusions” and that “an increased penetration of wind power reduces wholesale spot prices.”
“It has already been well-established that wind reduces CO2 emissions,” said Christian Kjaer, EWEA’s Chief Executive. “But now we have stronger evidence than ever before that wind power also reduces electricity prices for consumers. The message is clear – if you want affordable CO2-free electricity, increase the amount of wind power in your electricity mix.”
Wind power replaces CO2 -intensive production technologies, the report finds. The technology that sets the price on the wholesale market is usually hard coal. Wind replaces hard coal power plants during hours of low demand and gas-fired power plants during hours of high demand in all the countries the report analysed.
Wind’s impact comes about because its low marginal costs pushes more expensive technologies, such as gas and thermal plants, out of the market.

Wind has the potential to supply the worlds electricity five times over while producing almost no greenhouse gas emissions. Yet the US currently gets less than two percent of our electricity from wind power.

Wind: 50% of EU electricity in 2050
personalities told Europe’s largest wind energy conference and exhibition.
Topping the agenda at the opening day of the European Wind Energy Conference and Exhibition (EWEC 2010) in Warsaw was Europe’s long-term energy supply.
“2050 might seem like a long way off, but the decisions we take today will have a big impact on our energy supplies in 40 years’ time,” said Arthouros Zervos, President of the European Wind Energy Association (EWEA).
“A fully renewable power sector is the only solution to reaching 80-95% CO2 reductions by 2050,” he continued. “The remaining carbon emissions will be needed for other sectors, such as agriculture.”
However, we should be talking about a “renewable energy economy” not a low carbon one, Professor Zervos said. “Renewable energies can provide 100% of Europe’s power supplies by 2050 without any further contribution from any so-called low-carbon technologies.”
“Realistically, wind can provide 50% of power supplies by 2050 if the necessary changes to infrastructure and markets are made,” said Christian Kjaer, EWEA’s Chief Executive.

The United Nations Framework Convention on Climate Change (UNFCCC)
This work has deemed worth publishing
Human activities are releasing substantial amounts of gases, including carbon dioxide, that increase the natural greenhouse effect in the Earth’s atmosphere.
There is concern the addition of such gases will cause a further warming of the Earth’s surface and atmosphere, and this warming will have adverse effects on humans and natural ecosystems.
A number of regions are particularly vulnerable. They include: low-lying and other small island states; low-lying coastlines and flood-prone areas; areas liable to drought and desertification and fragile mountain ecosystems.
Countries should protect the world’s climate system for the benefit of present and future generations. Under the United Nations Charter, countries have the right to exploit their own resources, but they have the responsibility to ensure that activities under their control do not cause damage to the environment beyond their borders.
The global nature of climate change requires the widest possible cooperation by all countries and their participation in an effective and appropriate international response. Countries should enact effective environmental legislation to control greenhouse gas emissions and should ensure the functioning of natural processes that can remove some of the gases from the atmosphere.
The ultimate goal of the climate change Convention is to stabilize greenhouse gases in the atmosphere at levels that will not dangerously upset the global climate system. This should be done within a time frame that allows ecosystems to adapt naturally to climate change, ensures that food production is not threatened and enables economic development to proceed in a sustainable manner.
Most of the world’s greenhouse gas emissions have come and continue to come from developed countries, and they should take the lead in combating climate change and its adverse effects.
Developed nations, as well as a number of countries whose economies are in transition, such as in eastern Europe, shall adopt national policies and take measures to limit emissions of greenhouse gases. They shall also protect and improve forests and oceans, that act as sinks and reservoirs for greenhouse gases.
The aim for these nations is to reduce their emissions of carbon dioxide and other greenhouse gases to 1990 levels. (The emissions of some other greenhouse gases, which also damage the ozone layer, are being controlled under other international agreements.)
On a per person basis, greenhouse gas emissions from developing countries are still relatively low. For these countries, the first and overriding priorities are economic and social development, and eradication of poverty. The developing nations’ share of global emissions will grow as their economies expand, and they use more energy.
Some actions to address climate change can be justified economically, and can also help in solving other environmental problems. But a number of countries, particularly developing nations whose economies are dependent on fossil fuels, may have serious difficulties in switching to alternative fuels.
There are still many uncertainties about the timing, magnitude and regional impacts of climate change, but where there are threats of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing controls.
Developed countries shall help developing nations deal with requirements of Convention and the effects of climate change by:
- Providing money and technological assistance to help these nations measure flows of greenhouse gases.
- Assisting countries that are particularly vulnerable to harmful effects of climate change to meet the costs of adaptation.
- Providing environmentally sound technologies and know-how, as well as supporting the development of technologies within these nations.
- Provide information on quantities of greenhouse gases they release, and how much is absorbed by their sinks.
- Publish regular updates on programs to control emissions, and to adapt to climate change.
- Promote the sound management and conservation of such greenhouse gas sinks as plants, forests and oceans.
- Cooperate in planning for the impacts of climate change on coastal zones, water resources and agriculture.
- Cooperate in the protection of areas prone to floods or drought, particularly in Africa.
The convention sets up a specific group to help in the transfer of funds and technology to assist nations in controlling greenhouse gases and dealing with climate change. It will include the Global Environment Facility of the United Nations Development Programme, the United Nations Environment Programme and the International Bank for Reconstruction and Development.
For the convention to enter into force, it must be ratified by the national legislatures of at least 50 countries.
