Batteries often use potentially toxic chemicals such as nickel and cadmium to create electricity. It is estimated that around 94 per cent of dead batteries end up in landﬁll, which could lead to water pollution and damage soil microorganisms.
The National Solar Energy Centre (NSEC) in Newcastle is the only multi-collector facility of its type in Australia and home to the largest high-concentration solar array in the Southern Hemisphere.
Be aware of your water footprint. It can take as much as 16 000 litres of fresh water to produce one kilogram of beef.
Of all of the rubbish that makes it to the ocean, 15 per cent floats on the surface, 15 per cent remains near the shore and the rest sinks to the floor.
Of the 8000 animal-related insurance claims made to NRMA in NSW during 2008, over 6000 were caused by kangaroos. Motorists should drive carefully in country areas at dusk and dawn to reduce these casualties.

One in four Australians buys a new television each year. If current trends continue, by 2020 the energy used by televisions in this country will double that used by refrigerators.
Places on the Earth’s crust that conduct heat from below are called ‘hot rocks’. Australia has some of the richest sources of hot rocks in the world, in the form of high-heat producing granites. These could prove to be useful energy sources in the future.
Buy recycled paper. Every tonne of recycled paper can save 17 trees, 32 000 litres of water and enough electricity to heat a house for six months.
There is clear evidence that feral cats have had a heavy impact on the fauna of many Australian islands, and have probably contributed to the extinction of a number of native species.
Kangaroos use 5000 kilojoules per day while sheep require 15000 kilojoules. Lower energy requirements mean that kangaroos have less environmental impact and therefore may be better for human and pet food. Continue reading Did you know?
