Eight of Earth’s Most Unusual Plants

Rafflesia arnoldii: this parasitic plant develops the world's largest bloom

Rafflesia arnoldii: this parasitic plant develops the world’s largest bloom that can grow over 0ne metre across. It produces a foul odor and has a hole in the center that holds six or seven litres of water. The plant has no leaves, stems, or roots.

Why nuclear power is not the answer to climate change

TOO MANY REACTORS AND NOT ENOUGH CARBON REDUCTION

Studies performed by MIT, Commission on Energy, and International Atomic Energy Agency all agree that approximately 1500 to 2000 new atomic reactors would have to be built to reduce greenhouse gas emissions by enough to make a meaningful difference.

There are currently 449 nuclear power stations (approx), If we were running around 2000 reactors in total we would exhaust our main uranium reserves in a few decades. We would then need to mine lower grade uranium, this would itself cause more greenhouse emissions. If the potential 2000 reactors were used to replace the coal stations, we would have a 20% reduction in greenhouse emissions. If used as a new capacity to replace true renewable sources, then our emissions would actually increase.

TOO MUCH MONEY

1500 more reactors would cost trillions of dollars. New reactors going online in the US in the 1980s and 90s cost on average 4 billion dollars each. Reactors to recently come online in Japan in the last few years were in the order of $2000 / KW.

Taking an average larger power plant of 1200MW and an average conservative cost of $1250 / KW, this gives a construction cost of 1.5 billion.

Yearly costs per 1000kg of avoided CO2 emmisions are $68.9 for wind and $132.5 for nuclear power.

TOO MUCH TIME

Construction of 1500 new reactors means that we will need to open a new reactor every 2 weeks beginning today, for the next 60 years. This is impossible as the current nuclear manufacturers are only capable of doing half this amount if they are pushed to their absolute capacity. Climate change cannot wait for Nukes.

TOO MUCH WASTE

Operating another 1500 or more new reactors would create the need for a new Yucca Mountain sized radioactive dump site somewhere in the world every 3 to 4 years. Yucca Mountain has been in progress for almost 20 years and still is at least 10 years from being finished. The state of Nevada has also vigorously opposed the construction of the Yucca facility.

Due to the opposition to radioactive dump sites many countries including the US are attempting to reprocess the nuclear waste, as a means of managing the waste. This is a dangerous technology, linked with increased Leukemia rates amongst children living nearby reprocessing plants as a result of increased radiation being released into the surrounding environment.

Purchase green computers using “EPEAT”

EPEAT is a system which allows buyers to make informed decisions regarding the environmental impact of computer desktops, laptops and monitors before they go ahead and purchase them.

“EPEAT evaluates electronic products in relation to 51 total environmental criteria, 23 required criteria and 28 optional criteria. To qualify for registration as an EPEAT product, the product must conform to all the required criteria.”

“Products are also ranked in EPEAT according to three tiers of environmental performance – Bronze, Silver, and Gold. All registered products must meet the required criteria, and achieve Bronze status. Manufacturers may then achieve a higher level EPEAT “rating” for products by meeting additional optional criteria, as follows”:
