Do you know how many trees are cut down every day of the year? Neither do we, but over 1000 acres are deforested every day which the people at File Dropper, like many others, think is an obscene amount.

FileDropper want to help people store and share their documents electronically. We don’t want you to waste paper printing, so are offering 250GB file hosting accounts for free.

Take recycling to a new level with a “Keep Calm and Carry On” poster. Millions of copies were printed on the eve of World War II, but never displayed. And now the message has taken on a new lease with a different meaning in our credit crunched troubled times.

The simple five-word message is the very model of British restraint and stiff upper lip. Keep calm and carry on. Two-and-a-half million copies of “Keep Calm” were printed, to be distributed should a national catastrophe occur, but thankfully they remained in storage throughout the war.

Recent demand has seen 1000’s of orders being placed every month, and customers include 10 Downing Street and assorted embassies. The design has now been reproduced on T-shirts and coffee mugs, shopping bags and cufflinks.

You can’t beat the British Stiff Upper Lip

Any product with a name like Firewinder needs to be pretty darn cool. Thankfully, this decorative outdoor light is positively sub-zero as it actually visualises the wind’s energy. And that’s not dreamy hippy-speak, it’s a fact.

100% wind powered light!

100% wind-powered, Firewinder is unlike anything we’ve ever seen. By day it’s a relatively unobtrusive dangling corkscrew doodah that spins in the wind. But when night falls and the wind blows, it lights up, creating a beautiful spiralling effect.

The faster the blow the greater the glow, so in a real gust Firewinder becomes a pulsating pillar of light. It’s truly spellbinding and eco-friendly to boot.

Chester Zoo unveiled an ambitious plan that will see it transformed into the largest conservation, animal and leisure attraction of its kind in Europe.

The project – given the working title Natural Vision – will involve a £90 million first phase which will include the only domed ecosystem in the UK.

Called ‘Heart of Africa’, the bio-dome will be an African rainforest-themed sanctuary for a band of Gorillas, a large troop of chimpanzees, Okapi (rare giraffe-like creatures), and a wide variety of tropical birds, amphibians, reptiles, fishes and invertebrates, moving freely among lush vegetation.

The first phase will also include a 90-bed hotel, a Conservation College and a ‘Futures’ education centre. The rest of the Natural Vision project will be completed by 2018, thus creating one of the largest wildlife attractions in the world and support the zoo’s national and international conservation work, which already spans 50 countries.

Bikes are one of the best and cheapest ways to get around. Not only does the exercise keep you fit, the trip does very little damage to the environment.

As Bikes are powered by legs, there’s no chemicals, polution or waste resulting from their use. Bikes nowadays are made from mainly recyclable materials so they can be reused for years and when they are no longer able to be used they can be recycled rather than thrown away.

Children should be taught the many benefits of bike riding early in life and trained in personal and road safety while bicycling. Only then can they truly do the least harm possible - to themselves and the earth.

Wiggle is officially the UK’s number one online bike and cycle shop boasting nearly 10 years online, and have a huge January sale on, meaning you could save even more money on a new bike.

Remember it’s also possible claim taxable benefits if you cycle to work!
